Description

The green road route selection layout of central city based on the green road route selection potentiality quantitative assessment of city road Method
Technical field
The present invention relates to a kind of planning and designing method, and in particular to one kind is quantitatively commented based on the green road route selection potentiality of city road The green road route selection layout method of the central city of valency.
Background technology
The green road function of central city is understood
Green road (Greenway) concept and Planning Practice come from the U.S., by Olmstead (Frederick before more than 100 years Law Olmsted) park road (Parkway) started often is considered the predecessor in green road, i.e., by excavating linear vert space Development potentiality, is extended to the difference in functionalitys such as park, community and is formed a team, and is set up contact in-between, is served urbanite.Should Practice achieves well positive effect, and Correlative plan PRACTICE OF DESIGN thereafter is had a far reaching influence.
" green road (Greenway) " formally comes across the 1980's US President's Outdoor Recreation committee as technical term In the report of (President ' s Commission on Americans Outdoor), its description to green road is that " green road is We allow each resident easily to enter the support and vision of natural world.Green road be by the green finger created of place, it by What community was stretched out can connect and all communities through United States.They be possible to contact park, public or Privately owned forest and rural area rural area, and become as going on a hike, jogging, wild animal activity, ride and strolling about or have a rest of riding a bicycle is logical Corridor." from its describing it can be seen that the Core Feature in green road is the service of strolling about or have a rest, space connection and ecological protection etc. for green road Functional characteristics.
From region Lv Dao lay particular emphasis on offer the holiday service of strolling about or have a rest different, inner city Lv Dao is usually located in completed region of the city Portion and surrounding area, are associated with urbanite's daily life particularly closely, thus are weighed from its service function, and which should mainly carry For daily type and the short false type service of strolling about or have a rest, while having the functions such as traffic, cultural style and features displaying, ecology service concurrently.
The green road rank construction of central city
The rank system in the green road in the U.S. is generally divided into " region-city-community " three big ranks, plans phase with the green road of central city The mainly green road in city and two, the green road in the community rank that closes.Therefore, generally borrow in the green road Planning Practice in many cities of China The green road hierarchical approaches in the mirror U.S. are also divided into three ranks, and are generally divided into city and community two when the green road of central city is planned Individual rank is being planned and be controlled.
But from unlike the U.S., the average population scale in the current city of China and Space Scale are larger, cause many rule Draw the green road in city to be difficult directly effectively to be connected with the green road in community.As the green road in city is built, rank is higher, and simple lifting city is green Track density may result in the problems such as space and wasting of resources, while its length of the green road in the community of much planning, scale and reality Function actually also beyond the green road function limitation in community, assume responsibility for the function in the green road in urban.In consideration of it, this project is in east Battalion is provided with " city-city-community " three-level green road when planning green road rank system construction in downtown city, by the green road in city Arrange between the green road in city and community, effectively complete function transition and space linking, clear so as to position for more complete formation The green road net of the central city of clear, function system creates favorable conditions.
Table 1-1. central cities green road mark sheet at different levels
The green road space vehicles in inner city are understood
Green road dependent construction land type, therefore when green road is planned, which must adhere to various other types Land used operates the space vehicles that implements as green road.The green road of central city is due to its area characteristic and functional requirement, its main sky Between carrier be urban road and roadside linear Green Open Space (Linear Park, road prevention greenery patches etc.), and part Green road can also rely on Waterfront green field, ecology corridor outside of the city and discarded railway, highway and linear historic ruins (such as city wall Deng) layout, green its space vehicles of road of the central city of wherein different stage also emphasize particularly on different fields.
The green road route selection space vehicles subdivision in table 1-2 cities at different levels
Inner city space layout principle is understood
The Core Feature in the green road in inner city is to provide daily type and the short false type service of strolling about or have a rest for urbanite.The clothes of strolling about or have a rest The premise one side Shi Lv road itself of business function operation possesses certain service ability of strolling about or have a rest, and (requirement setting is taken a walk, rides, body-building Deng activity related facility), be on the other hand can by green road user easily be directed to Recreational resources concentrate location, i.e., from Spatially in demand for services end and the service supply side foundation contact of strolling about or have a rest of strolling about or have a rest, this is also the basic of the green road route selection layout of central city Principle.
Based on this, examine central city Lv Dao route selections layout process closely and can summarize three key points, i.e.,:
Route selection answer effectively connection Urban Recreation service supply gather location, such as park green land, ecological green land, city business Industry, culture, recreation center etc..
The location of gathering of effectively connection Urban Recreation demand for services, such as residential estate etc. are answered in route selection.
The space vehicles of route selection itself should possess carries out the condition of renovation and utilization according to green road functional requirement.
This three big key point also constitutes the basis of the green road route selection potentiality quantitative analyses of central city and premise.

Specific embodiment
Embodiment:
As shown in figure 1, the green road route selection potentiality quantitative analysis evaluation of central city is divided into five with variant projects of location formulation process Stage, and mainly rely on ArcGIS software platforms to complete.Five stages were respectively:The green road route selection potentiality sub-indicator of central city is fixed Amount evaluation, green road route selection potential comprehensive evaluation at different levels, other route selection factor Overlaying analysis, the green road route selection placement scheme of central city are pushed away Lead and formulate and the green road route selection placement scheme of central city verifies five stages.
First stage, the green road route selection potentiality sub-indicator quantitative assessment of central city
Corresponding central city three key points of green road route selection, route selection potentiality quantitative evalution model are made up of three class evaluation indexes, I.e.:Build suitability degree evaluation index in captivation of strolling about or have a rest evaluation index, recreation demand intensity evaluation index, green road.
In space vehicles feature discrimination, the green road main space carrier of central city is urban road and river course water system and along the line The banding open space constituted by greenery patches, also have under a few cases carries out the green road of route selection with key elements such as linear historic ruins.But Generally also can associate with urban road or river course water system along the green road of the layouts such as linear historic ruins, the green road master of such as City Wall in Nanjing It is moat road and roadside greenery patches to want space vehicles.Therefore, route selection is carried out as elementary cell with central city section and section Potentiality quantitative assessment also can be to effectively integrating along the green road of the key element layout such as linear historic ruins.
In three class evaluation indexes, captivation of strolling about or have a rest evaluation index and demand for services intensity evaluation index of strolling about or have a rest need Xian Dui centers City block is evaluated, and central city road (river) section evaluation of estimate need to be averaged generation according to road (river) section both sides block evaluation of estimate (Fig. 2);Green road is built suitability degree evaluation index and is then needed first to central city section section component analysises, and then generates central city road Build suitability degree evaluation of estimate in (river) Duan Lv roads.
For ease of green road route selection Potential Evaluation value to three class aggregations, three class indexs adopt ten point system, and with six grades Arranging each rank score value, score value is higher, is more suitable as green road route selection section for the form of arithmetic progression.
As shown in Fig. 2 cross part is city road in figure, the score value on four angles is block evaluation of estimate, on cross hairs Score value be road (river) section score value, blue arrow represents score value transfer process principle.
Three big core analysis evaluation indexes are described as follows:
Urban Streets are strolled about or have a rest captivation quantitative assessment:
According to service supply side Recreational resources attribute difference of strolling about or have a rest, captivation of strolling about or have a rest evaluation is divided into the greenery patches ecotype and strolls about or have a rest suction Gravitation (Fig. 3) and public humane type stroll about or have a rest captivation (Fig. 4) evaluate (5 points of full marks) two parts.Central city block is comprehensively strolled about or have a rest suction Gravitation evaluation of estimate (10 points of full marks) is generated (Fig. 5) by being superimposed the environmental and public two class evaluation of estimate of humane type in greenery patches, and then It is then transferred on central city road (river) section evaluation unit (Fig. 6).
Table 3-1. strolls about or have a rest captivation evaluation methodology
Recreation demand quantification of intensities is evaluated
Central city block demand for services source of strolling about or have a rest is divided into 2 classes by project, and a class is the service of strolling about or have a rest from residential estate Demand end, this are also main demand for services end of strolling about or have a rest in the middle of city, another kind of be non-residential estate demand for services end of strolling about or have a rest, Mainly urban transportation website, colleges and universities and hotel land used etc., this class demand for services proportion in the middle of the city of strolling about or have a rest are less.
The cardinal principle of demand intensity evaluation is strong by the residential estate area in central city block, residential estate exploitation (non-residential estate is strolled about or have a rest clothes to derive planning resident's population density inside central city block for degree, planning per capita living space etc. Mainly evaluated by its rank at business demand end).Bigger (the table 3- of the higher demand intensity of resident's population density in central city block 2).First evaluation (Fig. 7) is made for block recreation demand intensity in evaluation procedure, then block evaluation of estimate is overlapped to road (river) section (Fig. 8)
Table 3-2. city thoroughfares enclose block recreation demand intensity evaluation method
Rank Plan density of registered inhabitants (unit in block:People/hectare) Recreation demand intensity level
One-level ≥400 10
Two grades 300-400 8
Three-level 200-300 6
Level Four 100-200 4
Pyatyi ≤100 2
Six grades 0 0
Note:If enclosing region such as transport hub containing city-level, Transportation Centre land used, recreation demand intensity is set to one-level value 10, If the transport hub of level containing area, Transportation Centre land used, the unification of recreation demand intensity level is set to two grades of values 8
Green road route selection space vehicles suitability degree quantitative assessment
In view of the core route selection space vehicles in the green road of central city are urban road and river course, therefore the quantitative analysis evaluation model Suitability degree evaluation index is set mainly for urban road road (river) section, is related to non-motor vehicle isolation strip, bicycle lane, people's row Road, four parts (Fig. 9) of road (river) side greenbelt (containing greenery patches beyond boundary lines of roads, river's blue lines).
The green road route selection space vehicles suitability degree evaluation methodology of table 3-3. central cities
Green road route selection space vehicles suitability degree mainly evaluates urban road and its greenery patches along the line can be used for transforming or building If the urban road section type in green road and its constructing and implementing the suitable degree in space.Wherein, central city green road is constructed and implemented It is (green beyond containing boundary lines of roads that space generally involves non-motor vehicle isolation strip, bicycle lane, footpath, trackside greenbelt Ground) four parts.Therefore, to city section type and its construct and implement the evaluation in space and also enter mainly around four parts Row (table 3-3).
Second stage, green road route selection potential comprehensives at different levels are evaluated
Green road route selection Potential Evaluation value is generated by the weighted comprehensive of three class evaluation index values.Due to green road functions at different levels Positioning has differences, and the degree that stresses for three key points during route selection is also differed.City Lv Dao lays particular emphasis on integration The important Recreational resources in city, the therefore heavier connection depending on to Recreation supply end (such as high-level point of interest of strolling about or have a rest) of route selection process; The green road function in city is more balanced, therefore three key point attention degrees is closer to during route selection;Community Lv Dao stress for The daily trip of strolling about or have a rest of resident provides convenient service, and the connection to recreation demand end is more paid attention in therefore route selection.According to three ranks The function in green road stresses, and project team is by Delphi method, and carries out recurrence checking by result is generated by having put into practice case, from And the at different levels green road route selection potential comprehensive evaluation index for forming relative maturity calculates weight distribution value (table 3-4), in order to Dongying The green road route selection Potentials evaluation index in inner city carries out comprehensive superposition.
Rely on ArcGIS platforms that the evaluation score value of every central city road (river) section is carried out synthesis according to three sets of weights respectively Superposition is integrated, and is correspondingly formed three sets of select-line analysis evaluation figure (Figure 10, Figure 11, Figure 12) for the green road of different stage respectively, and Decision-making foundation directly perceived as the green road route selection at different levels of Dongying City inner city.
The green three big core analysis evaluation index of road in table 3-4. cities overlaps weight distribution
Phase III, other route selection factor Overlaying analysis
Built, Jian Lv roads circuit overlap
Present situation builds green road and covers 35.6 km urban roads altogether, is related to Huang Helu, Dong Sanlu, Dong Balu, north one Road, five, southern two tunnel urban road.The green road that builds up on five roads is should be used as in the green road planning route selection of this project Pre-conditioned, sufficiently effective integration need to be carried out in variant projects of location.In addition project also relates to be built building or list in the recent period Hua Lv roads totally 95 km is designed, and needs also exist for (Figure 13) is overlapped in variant projects of location.
Planning Experience of Ecological type and Xing Lv roads overlapping of strolling about or have a rest outside of the city
Dongying City planning Experience of Ecological type and Xing Lv roads of strolling about or have a rest outside of the city are comprising outer shroud Lv Dao, east green grass or young crops high speed Lv Dao, Nan Erlu Green road etc., is city Lv Dao.Wherein, east green grass or young crops high speed Lv Dao and Nan Erlulv roads have completed programme, enter into essence Construction period.The Liang Leilv roads are also both needed to be integrated (Figure 13) in the green road variant projects of location of project.
Green road route selection priority level overlapping
During green road route selection, sequentially route selection should be carried out according to rank height, i.e., first carry out the green road route selection in city, secondly The green road route selection in city is carried out, the green road route selection in community is finally carried out.Therefore, during green road route selection, such as occur with (river) section all the way In the green road route selection potentiality scoring of three ranks, all higher situation, will be selected according to the height order of itself rank of green road The preferential route selection in the green road of line, i.e. city is next to that city Lv Dao, be community Lv Dao (Figure 13) again.
Fourth stage, the green road route selection placement scheme of central city are derived and are formulated
After carrying out quantitative analyses and carrying out comprehensive integration with other correlative factors to the green road of each rank, prioritizing selection each Higher road (river) section of the green road route selection potential value of rank finally generates city Lv Dao, the green road layout side in the green road in city and community respectively Case, and the green road of three ranks of overlapping completes variant projects of location formulation (Figure 13) in the green road of central city on this basis.
5th stage, the green road variant projects of location checking of central city
It is that route selection result is further verified, project team chooses road by quantitatively comparing green road placement schemes at different levels (river) section and all alternative road (river) sections route selection potentiality meansigma methodss (Figure 14) of the rank, are tested to green road placement scheme performance Card.
After variant projects of location is completed, it is that route selection result is further verified, project team is by quantitatively comparing green road rule The scheme of drawing chooses road (river) section and all alternative road (river) section route selection potential value meansigma methodss (Figure 15) during green road route selection at different levels, can To find:
Table 3-5. green road alternative road (river) sections at different levels choose road (river) section route selection potential value in each interval distribution with scheme Information slip
Note:1. the green road in city alternative road (river) section be trunk roads, main stem and secondary distributor road, the green road in city alternative road (river) section For trunk roads, secondary distributor road and branch road and main stem and a fluid stream channel, the green road in community alternative road (river) section be secondary distributor road, branch road and Prop up fluid stream channel;2. choose green without the Experience of Ecological type and type of strolling about or have a rest outside of the city outside built-up areas in the green road key element potentiality Data-Statistics in city Road,
City Lv Dao chooses the route selection potentiality meansigma methodss of road (river) section be higher by 35.1% (figure of alternative road (river) section meansigma methodss 16), wherein 91.7% road (river) section of choosing is located at route selection potentiality high score (> 4) interval (Figure 15), than each corresponding alternative In road (river) section, high score road (river) section proportion (51.9%) will be higher by nearly 80% respectively.In route selection arrangement space effect, city The green road variant projects of location in city point of interest bonding ratio of strolling about or have a rest high-level to Dongying central city up to more than 95%, while connect central city each City, and form outer shroud and the green road loop wire of medium ring two-layer, built-up areas and its periphery outside of the city intersegmental set up ecological and stroll about or have a rest Contact tie (Figure 16).
City Lv Dao chooses the route selection potentiality meansigma methodss of road (river) section then be higher by alternative road (river) section meansigma methodss 41.2% (Figure 16), wherein about 84.9% to choose road (river) section to be located at route selection potentiality high score (> 4) interval, than alternative road (river) section in High score road (river) section proportion (39.2%) will be higher by nearly 120% (Figure 17).From in space layout effect, the green road series connection in city Inside each city, important point of interest and city Lv Dao fail the high-level point of interest of strolling about or have a rest that connects, while effectively connection city is each Function section, forms the three great Lv roads inner loop-lines for covering central city core space, has effectively been connected city and community Lv Dao (Figure 18).
Community Lv Dao chooses the route selection potentiality meansigma methodss of road (river) section be higher by alternative road (river) section about 38.3% (Figure 16), Alternative road (river) section entirety route selection potentiality integral level is limited by, chooses road (river) section to be located at the interval ratio of route selection potentiality high score Be only 34.3% again, but also index (14.3%) corresponded to than alternative road (river) section be higher by nearly 140% (Figure 19).Imitate in space layout On fruit, community Lv Dao is substantially finished the interspersed and insertion to all residential areas of Dongying, and the little of functional areas level of effectively having connected Type is strolled about or have a rest point of interest, while the green road loop wire of small range can be built up with common group of the green road in surrounding cities and city, forms one and is cased with The compound microcirculqtory system (Figure 20) of machine.
Compare according to quantitative result and route selection layout effect is parsed, given birth to based on route selection potentiality quantitative evalution model in the project Into the green road placement scheme of central city realize that substantially performance quantitative result is consistent with space layout effect, reach substantially planning pre- Phase target.
