Embodiment Construction

[0031] The invention is further described below in conjunction with specific embodiments:

[0032] A method for intelligently judging the suitability of immigrants in rocky desertification areas, comprising the following steps:

[0033] Step 1. Establish an index system, which includes landform C11, terrain C12, soil thickness C13, rocky desertification level C21, land cover C22, population density C31 and per capita GDP C32;

[0034] Step 2. According to the expert survey method, compare the importance of C11, C12, C13, C21, C22, C23, C31 and C32 to obtain the importance multiple relationship value of each index, and form the judgment matrix A;

[0035] Step 3: Standardize the judgment matrix A to obtain the matrix H;

[0036] Step 4: sum the elements of each row of matrix H to obtain matrix B;

[0037] Step 5: Standardize the matrix B to obtain the matrix W, and each element of the matrix W is the weight of each indicator;

[0038] Step 6: Check the consistency of the wei...

Abstract

The invention discloses a method for intelligently determining the suitability of immigration in a stony desertification area. On the bases of an analysis result of the importance degree of each indexby a Delphi method, an analytic hierarchy process is used to further determine the weight of the analysis result, thereby improving the accuracy of the importance degree of each index. Only the areasof different suitability evaluation indexes and the area and distribution of respective areas can be selected by comparing the grid value in a grid image formed by the analytic hierarchy process withthe suitability evaluation index assignment criteria. The method is easy and convenient to operate, high in degree of intellectualization, and high in degree of visualization, greatly reduces the human, material, and financial investment for suitability evaluation of the stony desertification areas in the prior art, is applicable to various stony desertification areas, and has good promotion adaptability.

Description

technical field [0001] The invention relates to an intelligent judgment method for the suitability degree of immigrants in a rocky desertification area, belonging to the field of rocky desertification control. Background technique [0002] The rocky desertification control project has always been one of the most urgent tasks in the entire southwest karst mountain area. In August 2004, the National Development and Reform Commission promulgated the "Notice on Further Improving the Guiding Opinions on the Comprehensive Control of Rocky Desertification in Southwest Rocky Mountains", and put forward five major engineering measures for comprehensive control of rocky desertification. By 2011, the comprehensive control of rocky desertification The project began to be officially implemented. However, there are differences in the natural environment, ecological environment, and social environment in different karst areas, so the selection of rocky desertification control projects oft...
