Quickly increase under the effect of exhibition pattern.In this process, generally there is all kinds of construction land and mix alternate
Phenomenon, as indenting in agricultural land, industrial land, residential estate etc..Land used mixes the impact brought
Cannot treat different things as the same, both advantageous and disadvantageous.The compatible organic mixing between all kinds of lands used can promote all kinds of
The maximum performance of land used usefulness, the mixing of such as residential estate and commercial land, not only facilitate the daily of people
Life, also will promote the more preferable development of business；With the mixing of warehouse land, industry also will significantly promote that industry is raw
Produce the raising of efficiency." white land " (in vain) of Singapore, in the classification of Beijing city land character
" F " class land used (multi-functional land used, the area of mixed usage of several mutual noiseless facilities), all to area of mixed usage
Effectively attempt.But, incompatible land used mixing then can bring entirety or the reduction of certain class land used usefulness,
Such as the industrial land of primary study and the mixing of residential estate in the present invention, living environment can be produced different journey
The adverse effect of degree.Therefore, in planning construction, advocate compatible area of mixed usage, it is to avoid incompatible is mixed
Have become as common recognition with share.And the most accurately calculate evaluate Land_use change severity of mixing up become first have to solve
Problem certainly.
Currently, about the severity of mixing up evaluation of Land_use change, the more area utilizing all kinds of land used of planning aspect
The simple mode such as ratio and change thereof carries out quantitative analysis, also only resides within that " land used mixes, industry occupies
Live land used indenting " qualitative description on, research field does not proposes metering method targetedly yet.And
In landscape ecology field, the feature of Land_use change is had more systematic research, and establishes landscape pattern and refer to
Counting method, the most just includes relating to the landscape richness of Land_use change hybrid UV curing, landscape heterogeneity, view many
The indexs such as sample, mix describing all kinds of lands used, various propose a kind of new thinking, compare qualitative description
Deepen, but but its research core has paid close attention to Characters of landscape patterns and ecological process two broad aspect, land used class
Type mostly is the non-constructive land such as farmland, forest, meadow, waters, more concern ecosystems, species diversity
Property etc. partially problem in terms of landscape ecological.Urban planning field then focuses more on relevant to mankind's construction activity
Problem, therefore, when directly index of landscape ecology method being applied to urban planning domain analysis, exist
The problems such as analysis personnel is the most corresponding, purport is indefinite, index use is inadaptable.Therefore, the present invention is existing
On the basis of having landscape ecology landscape indices, develop a kind of Land_use change based on Compatibility in land use
Hybrid UV curing evaluation model, has, for estimating Land_use change severity of mixing up, well adapting to property.
Summary of the invention
It is an object of the invention to provide a kind of method estimated and evaluate Land_use change hybrid UV curing.Hold concurrently based on land used
This new angle of capacitive removes to redefine hybrid UV curing, and by setting up Land_use change hybrid UV curing evaluation model
Carry out quantitative Analysis, then set up associating between hybrid UV curing index with urban environment performance, make hybrid UV curing have
There is clear and definite evaluative meaning.
The purpose of the present invention is realized by following technical scheme.
1. a Land_use change hybrid UV curing evaluation methodology based on Compatibility in land use
The first step determines cell yardstick
That is one square of one cell, determines the name of this cell according to the land-use style in cell
Claim, such as flat lattice, commercial unit lattice, storage cell etc..Then ground is used according to analyze
The long-pending scale size determining cell, length of side span is [50m, 200m],
As land area≤5km2Time, the length of side takes 50m；
Work as 5km2＜ land area≤20km2Time, the length of side takes 50m 100m；
As land area ＞ 20km2Time, the length of side takes 100m 200m；
Second step lays grid
One nested grid is made up of the cell of 9 or more than 9 equal sizes.One inhabitation speckle correspondence one
Nested grid, and lay grid using the center of gravity of each inhabitation speckle as unit center of a lattice, grid is finally wanted
Whole inhabitation speckle can be covered；
3rd step determines analytic unit
First, defined analysis unit.One analytic unit is by the flat at residential estate speckle center of gravity place
8 cell compositions that lattice and periphery are adjacent.Analytic unit is by the minimum unit that hybrid UV curing calculates；
Secondly, residential estate, industrial and storage land are proposed different specklees and define regular:
One, for residential estate:
One inhabitation speckle can be made up of one or more flat lattice according to its size, inhabitation speckle
Block area is the biggest, and corresponding flat lattice quantity is the most, and specific rules is as follows:
(1) for area less than the isolated inhabitation speckle of cell, or two areas are less than the orphan of cell
When vertical its center of gravity of inhabitation speckle is in same cell, it is defined as flat lattice；
(2) any two center of gravity is not to the neighbourhood speckle of same cell, if they borders it
Between space sufficiently large, during vertical dimension >=50m between speckle, as two separate inhabitation speckles
Block；Otherwise, merging is calculated as flat lattice；
(3) for spreading across several cells, but unfilled unit lattice is long and narrow or irregular
Special-shaped inhabitation speckle, uses and cuts reinforcement: if it exceeds the area of main body place cell is less than cell
1/2, then it is left in the basket beyond area；Otherwise, flat lattice will should be defined as beyond part；
Two, for industrial and storage land:
Introduce the algorithm ignoring ratio H, i.e. during the calculating mixing index, when industrial and storage land accounts for
When the area of its place cell is less than cell area with the product ignoring ratio, this industrial and storage land quilt
Ignore, otherwise, it is denoted as commercial unit lattice.Ignore the span of ratio H for (0,1], and
According to inhomogeneity industrial and storage land the influence degree of residential estate determined the size ignoring ratio, pollutes
The biggest, ignore ratio the least.Three classes industry (M3), two classes industry (M2), class industry (M1) etc. three
The pollution level of residential estate is reduced by kind of industrial land successively, therefore, three kinds of industrial lands ignore ratio
Rise the most successively, i.e. HM3 < HM2 < HM1；
4th step cell assignment
Employing " nine grids, i.e. 3 × 3 " is as the aid of assignment, to involved by each inhabitation speckle
Analytic unit carries out assignment, and assignment rule is as follows:
(1) using the cell at this inhabitation speckle place as the center cell lattice of nine grids, one is given
" basic value " " 1 "；
(2) each adjacent cells lattice of center cell are given one " adjacent value ", adjacent value size according to
Periphery land used carrys out assignment with the compatibility of residential estate, the biggest on living environment impact, the most incompatible, assignment
The highest, concrete assignment rule is as follows:
If the construction land that a. adjacent cells lattice cover is all residential estate, then " the adjacent value " of this grid
It is exactly " 0 "；
If b. industrial and storage land, then according to " Standard for classification of urban land and for planning of constructional land (GB
In 50137-2011) ", the compatibility for these lands used Yu residential estate carrys out assignment: a class industrial land is
To live and public environment is the most noiseless, pollute and the industrial land of potential safety hazard, be entered as " 1 "；Two
Class industrial land is to have certain interference, pollution similar with the industrial land of potential safety hazard with public environment to living
Land used, is entered as " 2 "；Three class industrial lands are for having severe jamming to inhabitation and public environment, pollute and pacify
The industrial land of full hidden danger, then assignment " 3 "；Warehouse land is unified is entered as " 1 "；
If the construction land that c. adjacent cells lattice cover is the land-use style outside inhabitation, industry storage, unified
It is entered as " 0 "；
(3) in the example shown, " basic value: 1 " and " adjacent value: 0,1,2 or 3 " is shown in grid；
(4) total assignment of each inhabitation analytic unit adds 8 adjacent net of its periphery equal to " basic value "
" the adjacent value " that lattice give；
5th step hybrid UV curing index M DI (Mixed degrees Index) calculates
For the hybrid UV curing index calculation method of some inhabitation analytic unit j be by actual mix assignment and
Possible theoretical maximum (i.e. 25) compares, and specific formula for calculation is as follows:
Wherein: n is the flat lattice number being covered by residential estate speckle or cutting in analytic unit j；
Ni represent in analytic unit j i-th flat lattice mix assignment；25 is that a flat mixes
The maximum assignment of miscellaneous degree；
Hybrid UV curing index M DI value scope is [0,1], when residential estate periphery is residential estate or removes industry storehouse
During other lands used outside storage, severity of mixing up is minimum, and value is 0；When residential estate periphery is all three class industry
During land used, severity of mixing up is maximum, and MDI value is 1；It is between 0 to 1 that other situations mix index M DI value.
Hybrid UV curing index M DI is the biggest, and land used more mixes, and living environment is the poorest.Therefore, big according to MDI index
I tentatively obtains industry storage based on living environment effect, residential estate hybrid UV curing evaluation.
Further, described Land_use change hybrid UV curing evaluation methodology based on Compatibility in land use, it is characterised in that institute
Stating the yardstick of cell, the length of side takes 100m.

When vertical its center of gravity of inhabitation speckle is in same cell, it is defined as flat lattice；
(2) any two center of gravity is not to the neighbourhood speckle of same cell, if they borders it
Between space sufficiently large, during vertical dimension >=50m between speckle, as two separate inhabitation speckles
Block；Otherwise, merging is calculated as flat lattice；
(3) for spreading across several cells, but unfilled unit lattice is long and narrow or irregular
Special-shaped inhabitation speckle, uses and cuts reinforcement: if it exceeds the area of main body place cell is less than cell
1/2, then it is left in the basket beyond area；Otherwise, new flat lattice will should be defined as beyond part；
For industrial and storage land:
(1) algorithm of ratio is ignored in introduction, i.e. during the calculating mixing index, when industry storage is used
Account for the area of its place grid less than grid area with when ignoring the product of ratio, this industrial land is left in the basket
Disregarding, the codomain ignoring ratio should be [0,1].Such as grid cell yardstick is 100m, when ignoring ratio is
When 0.1, if industrial land accounts for the area of its place grid less than 100*100*0.1, this industrial land will
Be left in the basket, i.e. this grid does not represent industrial land, as in Fig. 5 No. 6 grids (dark color is industrial land, shallow
Color is residential estate, lower same)；If industrial land accounts for the area of its place grid more than 100*100*0.1,
Then it is designated as an industrial grid, such as No. 5 grids in Fig. 5.
4. cell assignment

" the adjacent value " given；
Example as shown in figure 12, the construction land that adjacent mesh covers is residential estate, and " adjacent value " is " 0 ",
Always it is entered as " 1 "；
Example as shown in figure 13, the construction land that adjacent mesh covers is the land used outside inhabitation, industry storage
Being entered as " 0 ", total assignment is also " 1 "；
Example as shown in figure 14, the combination that construction land is all kinds of land used that adjacent mesh covers, be entered as 0,
1,2,3, always it is entered as " 13 "；
Example as shown in figure 15, the construction land that adjacent mesh covers is three class industrial lands, and total assignment is also
“25”；
5. hybrid UV curing index M DI (Mixed degrees Index) calculates
For the hybrid UV curing index calculation method of some inhabitation analytic unit j be by actual mix assignment and
Possible theoretical maximum (i.e. 25) compares, and specific formula for calculation is as follows:
Wherein: n is the flat lattice number being covered by residential estate speckle or cutting in analytic unit j；
Ni represent in analytic unit j i-th flat lattice mix assignment；25 is that a flat mixes
The maximum assignment of miscellaneous degree；
Hybrid UV curing index M DI value scope is [0,1], when residential estate periphery is residential estate or removes industry storehouse
During other lands used outside storage, severity of mixing up is minimum, and MDI value is 0；When residential estate periphery is all three classes
During industrial land, severity of mixing up is maximum, and MDI value is 1；It is 0 to 1 that other situations mix index M DI value
Between.Hybrid UV curing index M DI is the biggest, and land used more mixes, and living environment is the poorest.Therefore, refer to according to MDI
The big I of number tentatively obtains industry storage based on living environment effect, residential estate hybrid UV curing evaluation.
Improve efficiency to simplify calculating, develop special computing according to the above-mentioned computational methods mixing index
Software, and carried out exemplary application test.As a example by choosing Wuxi Jiangyin City, Foshan Shunde District, utilization mixes
Index for Calculation computed in software also compares two places inhabitation, the severity of mixing up of industrial and storage land in 2010.Figure 16
It is respectively residential estate hybrid UV curing Index for Calculation interface, Shuande 2010 and Jiangyin 2010 residential estate with Figure 17
