Abstract: Through analysis of environmental status of Xiong’an New Area, from three dimensions of water environment, atmospheric environment and geological environment, evaluation index system of environmental carrying capacity of the New Area is preliminarily designed. By using correlation analysis and principal component analysis, 11 basic indexes, including Industrial waste water discharge per 10000 yuan GDP, Comprehensive index of air quality and Average groundwater depth etc., are selected to construct the evaluation index system of environmental carrying capacity of Xiong’an New Area. Based on the fuzzy comprehensive evaluation method, the environmental carrying capacity of the New Area from 2014 to 2018 are evaluated, which provides the basis for protection and utilization of water environment, atmospheric environment and geological environment. The results show that: environmental carrying capacity of the New Area from 2014 to 2018 is 0.2186, 0.2109, 0.2153, 0.2415 and 0.2690 respectively, showing a steady growth trend, mainly as the environmental control of water and atmosphere have been strengthened after 2017.
Keywords: Xiong’an New Area, environmental carrying capacity, correlation analysis, principal component analysis, fuzzy comprehensive evaluation method
