镇江市水环境安全评价指标体系的建立与筛选

Establishment and Screening of Evaluation Index System for Water Environment Safety in Zhenjiang

在研究镇江市水环境基本状况的基础上,结合指标体系构建原则,采用"压力—状态—响应"(PSR)模型初步建立了镇江市水环境安全评价指标体系,进而依据指标筛选原则,依次运用相关分析、层次分析、主成分分析3种方法对指标体系进行筛选,得到了较合理的镇江市水环境安全评价指标体系。

Based on study of water environment state in Zhenjiang and combined with the construction principle of index system, the evaluation index system for water environment safety in Zhenjiang was primarily established with the pressure-state-response（PSR） model. The index system was screened by correlation analysis, hierarchy analysis and principal component analysis, and then the reasonable evaluation index system for water environment safety in Zhenjiang was obtained.
