Description
Technical field
The present invention relates to a kind of method of estimating and evaluating land utilization ratio, be specifically related to a kind of based on compatibility of field, to living, the evaluation method of the soil utilization degree of mixing of industry storage two large class lands used.
Background technology
The present invention relates to soil and utilize field, this land used degree of mixing model is applicable to degree of the mixing evaluation of all kinds of construction lands, but because the compatible situation between all kinds of lands used is comparatively complicated, be difficult to go to summarize by unified standard, therefore, emphasis of the present invention is chosen inhabitation, example studies is carried out in industrial measuring and calculating and evaluation of storing in a warehouse two large class land used severity of mixing up.Take residential estate as core evaluation object, developed that a kind of calculating based on living environment effect (settlement performance-oriented) is lived, the index method of industry storage two large class land used degree of mixing, come quantitatively evaluating because of the impact of living, the large class lands used mixing of industry storage two produce.
In China, completed region of the city is rapid growth under the effect of " opening up outside city " and " local towns is spread " these two kinds of development models normally.In this process, ubiquity all kinds of construction lands and is mixed alternate phenomenon, as agricultural land, industrial land, residential estate interlocking etc.Land used mixes the impact bringing and cannot treat different things as the same, both advantageous and disadvantageous.Organic mixing between compatible all kinds of lands used can promote the maximum performance of all kinds of land used usefulness, for example mixing of residential estate and commercial land, and not only convenient daily life, also will promote the better development of business; Industry will significantly promote the raising of commercial production efficiency with mixing also of warehouse land." white land " (in vain) of Singapore, " F " class land used (multi-functional land used, the area of mixed usage of several mutual noiseless facilities) in the land used qualitative classification of Beijing city, is all the effective trial to area of mixed usage.But incompatible land used mixes the reduction that can bring integral body or certain class land used usefulness, as mixing of the industrial land of primary study in the present invention and residential estate, can be to living environment generation adverse effect in various degree.Therefore, in planning construction, advocate compatible area of mixed usage, avoid incompatible area of mixed usage to become common recognition.And how accurately the severity of mixing up of measuring and calculating evaluation soil utilization becomes the problem that first will solve.
Current, the severity of mixing up evaluation utilizing about soil, planning aspect is more utilizes the simple modes such as the area ratio of all kinds of lands used and variation thereof to carry out quantitative test, also only rest on the qualitative description of " land used mixes, industrial residential estate indenting ", research field does not propose metering method targetedly yet.And in landscape ecology field, the feature of soil utilization is had to comparatively systematic research, and set up landscape indices method, wherein just comprise the landscape richness that relates to soil utilization degree of mixing, landscape heterogeneity, the indexs such as landscape diversity, to describing mixing of all kinds of lands used, various a kind of new thinking proposed, than qualitative description, deepen to some extent, but but its research core is paid close attention to Characters of landscape patterns and ecological process two broad aspect, land used type mostly is farmland, forest, meadow, the non-construction land such as waters, more concern ecosystems, the problem of species diversity isogonic landscape ecological aspect.The problem relevant to mankind's construction activity paid close attention in city planning field more, therefore, while directly index of landscape ecology method being applied to city planning domain analysis, exists the problems such as analysis personnel is not corresponding, purport is indefinite, index use is inadaptable.Therefore, the present invention, on the basis of the ecological landscape indices of present landscape, has developed a kind of soil utilization degree of mixing evaluation model based on compatibility of field, for estimating soil, utilizes severity of mixing up to have good adaptability.
Summary of the invention
The object of this invention is to provide a kind of method of estimating and evaluating soil utilization degree of mixing.Based on this new angle of compatibility of field, remove to redefine degree of mixing, and quantitatively calculate by setting up soil utilization degree of mixing evaluation model, then set up associated between degree of mixing index and urban environment performance, make degree of mixing there is clear and definite evaluative meaning.
Object of the present invention is realized by following technical scheme.
1. soil utilization degree of the mixing evaluation method based on compatibility of field
First step determining unit lattice yardstick
A cell is a square, determines the title of this cell according to the land used type in cell, as flat lattice, commercial unit lattice, storage cell etc.Then according to the scale size of the land area determining unit lattice that will analyze, length of side span is [50m, 200m],
As land area≤5km
2time, the length of side is got 50m;
Work as 5km
2< land area≤20km
2time, the length of side is got 50m-100m;
As land area > 20km
2time, the length of side is got 100m-200m;
Second step is laid grid
One nested grid is comprised of the cell of 9 or 9 above equal sizes.The corresponding nested grid of inhabitation patch, and using the center of gravity of each inhabitation patch and lay grid as unit center of a lattice, grid is finally wanted to cover whole inhabitation patch;
The 3rd step is determined analytic unit
First, defined analysis unit.8 cells that analytic unit is adjacent by flat lattice and the periphery at residential estate patch center of gravity place form.Analytic unit is the minimum unit that degree of mixing calculates;
Secondly, residential estate, industrial and storage land are proposed to different patch definition rules:
One, for residential estate:
An inhabitation patch can be comprised of one or more flat lattice according to its size, and inhabitation plaque area is larger, and corresponding flat lattice quantity is also more, and specific rules is as follows:
(1) for area, be less than the isolated inhabitation patch of cell, or isolated its center of gravity of inhabitation patch that two areas are less than cell is in same cell time, is defined as flat lattice;
(2) for any two centers of gravity adjacent inhabitation patch in same cell not, if the space between their borders is enough large, during vertical range >=50m between patch, as two separate inhabitation patches; Otherwise, merge and count flat lattice;
(3) for stretching, cross over several cells, but do not fill up the long and narrow or irregular special-shaped inhabitation patch of unit lattice, adopt and cut reinforcing method: if surpass the area of main body place cell, be less than 1/2 of cell, exceed area and be left in the basket; Otherwise this exceeds part will be defined as flat lattice;
Two, for industrial and storage land:
The algorithm of ratio H is ignored in introduction, in mixing the computation process of index, when the area that accounts for its place cell when industrial and storage land is less than cell area and ignores the product of ratio, this industrial and storage land is left in the basket and disregards, otherwise, be denoted as commercial unit lattice.The span of ignoring ratio H for (0,1], and according to inhomogeneity industrial and storage land, the influence degree of residential estate is determined to the size of ignoring ratio, pollute greatlyr, ignore ratio less.Three kinds of industrial lands such as three class industry (M3), two class industry (M2), a class industry (M1) reduce successively to the pollution level of residential estate, therefore, the ratio of ignoring of three kinds of industrial lands rises successively, i.e. HM3<HM2<HM1;
The 4th step cell assignment
, as the aid of assignment, the analytic unit related to each inhabitation patch carries out assignment to adopt " nine grids, 3 * 3 ", and assignment rule is as follows:
(1) using the cell at this inhabitation patch place as the center cell lattice of nine grids, give one " basic value " " 1 ";
(2) to each adjacent cells lattice of center cell, give one " adjacent value ", adjacent value size is carried out assignment according to the compatibility of periphery land used and residential estate, and larger, more incompatible on living environment impact, assignment is higher, and concrete assignment rule is as follows:
If the construction land that a. adjacent cells lattice cover is all residential estate, " the adjacent value " of this grid is exactly " 0 " so;
If industrial and storage land b., according to carrying out assignment for the compatibility of these lands used and residential estate in the > > of < < Standard for classification of urban land and for planning of constructional land (GB50137-2011): a class industrial land is for to living and public environment is substantially noiseless, the industrial land of pollution and potential safety hazard, and assignment is " 1 "; Two class industrial lands are for there being the similar land used of industrial land of certain interference, pollution and potential safety hazard with public environment to living, assignment is " 2 "; Three class industrial lands are for to living and public environment has the industrial land of severe jamming, pollution and potential safety hazard, assignment " 3 "; Warehouse land is unified assignment for " 1 ";
If the construction land that c. adjacent cells lattice cover is the land used type outside inhabitation, industry storage, unified assignment is " 0 ";
(3), in diagram, " basic value: 1 " and " adjacent value: 0,1,2 or 3 " is shown in to grid;
(4) total assignment of each inhabitation analytic unit equals " the adjacent value " that " basic value " adds that 8 adjacent mesh of its periphery are given;
The 5th step degree of mixing index M DI (Mixed degrees Index) calculates
For degree of the mixing index calculation method of some inhabitation analytic unit j, for mix assignment and the possible theoretical maximum (25) of reality are compared, specific formula for calculation is as follows:
Wherein: n is the flat lattice number that is covered or cut by residential estate patch in analytic unit j; Ni representative in analytic unit j i flat lattice mix assignment; 25 is the maximum assignment of a flat severity of mixing up;
Degree of mixing index M DI value scope is [0,1], and when residential estate periphery is residential estate or other lands used except industry storage, severity of mixing up is minimum, and value is 0; When residential estate periphery is all three class industrial lands, 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.DI is larger for degree of mixing index M, and land used more mixes, and living environment is poorer.Therefore, according to the large I of MDI index, tentatively obtain industry storage, the evaluation of residential estate degree of mixing based on living environment effect.
Further, described soil utilization degree of the mixing evaluation method based on compatibility of field, is characterized in that the yardstick of described cell, and the length of side is got 100m.
Core content of the present invention be take living environment effect as interpretational criteria, based on compatibility of field, proposed a kind of index calculation method of estimating inhabitation, industry storage two large class construction land degree of mixing, evaluated inhabitation, mixing of industry storage two large class lands used utilize the impact that living environment is brought.
The design key of degree of mixing index calculation method is to live, on the basis of industrial and storage land severity of mixing up, set up associated between land used degree of mixing and living environment performance effectively calculating.Therefore, interpretational criteria choose very crucial.Industrial and storage land presents negative external effect to residential estate, and we select the compatible degree between heterogeneity land used to be used as the interpretational criteria of land used degree of mixing and living environment quality, and compatibility is better, and degree of mixing is less, and living environment effect is better.
Beneficial effect of the present invention and Core Superiority
(1) realizing soil utilizes severity of mixing up evaluation from the transformation of qualitative to quantitative.In research in the past or physical planning work, for soil, utilize the more employing qualitative evaluation of severity of mixing up, when soil that need to more two or more areas utilizes severity of mixing up, qualitative evaluation tends to be difficult to separate the sheep from the goats, just.The present invention is by setting up soil utilization degree of mixing evaluation model, introducing degree of mixing index, utilizing severity of mixing up to change into index assessment from subjective assessment in soil, be applicable to comparison and the comparison of self many time period between multi-object, is supplementary perfect to qualitative evaluation.
(2) take living environment effect as evaluating starting point, set up and mixed contacting directly between index and living environment benefit, mix index higher, habitation environment quality is poorer, thereby can mix the quality that index judges a regional habitation environment quality by calculating.
