摘要
随着我国经济的高速发展,水环境的可持续发展成为十分重视的问题。三峡库区作为长江干流最重要的部分之一,其水质情况将直接或者间接影响长江流域的水环境状况,从而影响我国的经济发展。文章根据三峡库区2008年—2017年p H值(7.63)、DO含量(8.5 mg/L)、CODMn含量(1.71 mg/L)、氨氮含量(0.1 mg/L)的监测数据,以及潜在的多项水质影响因素的多方统计数据,利用典型相关分析法对筛选出的6项水质影响因素与4项水质指标间的两个整体系统的相关性进行研究。根据分析得出的典型相关系数(1.000、0.960、0.895)、典型相关模型以及典型结构分析和冗余分析的结果,证明了两个系统存在着显著的相关性。
With the rapid development of our country′s economy,the sustainable development of water environment has become an extremely important issue.Three Gorges Reservoir area is one of the most important parts of the Yangtze River main stream.Its water quality will directly or indirectly affect the water environment of the Yangtze River basin,which will affect our country′s economic development.Based on the monitoring data of p H value(7.63),concentration of DO(8.5 mg/L),CODMn(1.71 mg/L),ammonia nitrogen(0.1 mg/L)in water of Three Gorges Reservoir area from 2008 to 2017,as well as the multilateral statistical data of potential water quality influencing factors,the article used canonical correlation analysis method studies correlation of two overall systems between six selected water quality influencing factors and four water quality indices.According to the analysis of typical correlation coefficients(1.000,0.960,0.895),the canonical correlation model,and the analysis of typical structure result of redundancy analysis,it proved that there was a significant correlation between two systems.
