Problems solved by technology

However, in the field of urban planning, more attention is paid to issues related to human construction activities. Therefore, when the method of landscape ecology index is directly applied to the analysis of urban planning, there are problems such as mismatched analysis subjects, unclear themes, and inappropriate use of indicators.

Embodiment Construction

[0065] The structure of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0066] The detailed operation and instructions are as follows:

[0067] 1. Determine the cell scale

[0068] First determine the cell scale. Under normal circumstances, a cell scale of 100m*100m can be adopted. In addition, the cell scale can also be determined according to the current characteristics of local land use and actual construction experience. For example, when defining a cell of residential land, the average area of ​​the local residential land plot can be used as the basic scale of the cell.

[0069] 2. Layout grid

[0070] After determining the cell scale, the grid is arranged with each residential patch as the core, that is, one residential patch corresponds to a set of grids. The specific method is: take the center of gravity of each residential patch as the center of the cell to expand the grid to cover the entire reside...

Abstract

The invention relates to a method of measuring and evaluating land use rate, in particular to a land use mixing degree evaluation method based on land use compatibility. The method includes: 1, determining cell dimensions and determining dimensions of square cells according to land area of an analytic object; 2, laying out the cells, expanding the cells to cover an area of residential plagues by using centers-of-gravity of the residential plagues as centers of the cells; 3, determining an analysis unit, and providing different plague definition rules for residential lands and industrial warehousing lands; 4, assigning the cells; 5, calculating MDI (mixing degree indexes), and comparing values of the MDI to a probable theoretical maximum to achieve mixing degree evaluation. Land use mixing degree of a region and merits of residential environment quality are judged by calculating the mixing degree indexes, so that land use mixing degree evaluation is not qualified but quantitated and valuable reference information can be provided for the planning and decision of urban land use.

Description

technical field [0001] The invention relates to a method for measuring and evaluating land use ratio, in particular to a method for evaluating the mixed degree of land use for residential land and industrial storage land based on land use compatibility. Background technique [0002] The present invention relates to the field of land use. This land use mixing degree model is suitable for the evaluation of the mixing degree of various construction lands. However, due to the complexity of the compatibility between various types of land use, it is difficult to generalize through a unified standard. Therefore, the present invention Focusing on the calculation and evaluation of the mixing degree of two types of land use, residential and industrial storage, for example research. Taking residential land as the core evaluation object, an index method for calculating the mixed degree of residential and industrial storage land based on the settlement performance-oriented effect was dev...
