- Abstract:
-
In view of the environmental impact assessment of land use planning system’s uncertainty, an improved set pair analysis( SPA) model is quoted that utilizes SPA theory and the malleability of the original relation degree to extend the comprehensive evaluation ranking of the environmental impact assessment of land use planning from 3 levels to 4 levels.We established the regional natural quality assessment index system consisting of water environment sub-system, soil environment sub-system, atmosphere environment sub-system and ecological environment sub-system.It can be used for obtaining the environmental impact assessment of land use planning level in different years of Jincheng City based on 10 influential factors with the theory of entropy weight and improved SPA.The comprehensive evaluation results of proposed model of the evaluation of the environmental impact assessment of land use planning are compared with the results of improved fuzzy comprehensive evaluation and comprehensive assessment to prove the rationality of improved SPA.The results indicated that since the implementation of the third-round land use planning, there was an overall improvement from Ⅲ to Ⅰ in the natural environment quality from 2007 year, 2009 year, 2011 year and 2013 year in Jincheng City. Compared with fuzzy comprehensive evaluation and comprehensive assessment, the results of three methods are basically consistent.Then it shows the evaluation results of improved SPA are reliable, reasonable and visualized, and the improved SPA is a scientific and practical evaluation method that can more carefully describe the environmental impact assessment of land use planning.
