江苏省主要河流水环境状况综合评价研究

Study on Comprehensive Evaluation of Major Rivers in Jiangsu Province

为综合评价江苏省主要河流水环境状况,基于江苏省境内三大流域13条主要河流35个采样点的生物和理化数据,采用因子分析和相关分析法建立了兼顾生物信息和理化信息的河流综合评价体系,并采用对应分析法分析了影响评价结果的原因。结果表明,江苏省主要河流水环境状况不容乐观,营养元素氮排放可能是重要原因。

Based on biologic and physicochemical data from 35 sampling point of 13 maior rivers in Jiangsu Province, a system {or comprehensive evaluation of rivers, considering both aspects of biologic and physicochemical characteristics, has been established with the help of factor analysis and correlation analysis to master the whole water environment situa- tion. Furthermore correspondence analysis is used to explain the comprehensive evaluation results. The results show that the wa- ter environment situation of major rivers in Jiangsu Province is not optimistic and the nitrogen emission may be important reason.
