北京市城近郊区河流水污染分析

以北京市1997～2001年城近郊区河流的监测资料为依据,采用主成分分析方法,识别得出北京市城近郊区河流的水污染成因,并依据主成分得分进行聚类分析。结果表明北京市城近郊区河流为有机污染型,主要污染物为NH3-N、COD、BOD;另外,针对聚类分析得出的4个水环境区域的污染成因和污染因子提出了相应的微观控制措施,为按水环境功能区划进行有目的、有重点的达标治理提供了科学依据。

Analysis of river pollution in the near suburban of Beijing

Statistical Program for Social Sciences(SPSS)software was applied for principle component and cluster analysis of river pollution monitoring data from 1997 to 2001 in Beijing near suburban area.The results indicated that organic pollution was the main problems and the NH_3-N,COD and BOD are main indicators.The pollution genesis and factors in four water environment clusters were performed by clustering analysis of data from detecting points on rivers.Furthermore,in this study microcosmic control measure was proposed in order to provide the scientific reference of river pollution harnessing according to the function partition of water environment.
