基于主成分分析的清水河水质影响因子研究

摘要

以张家口市内景观河—清水河老鸦庄和北泵房监测断面2012-2015年水质监测资料为依据,选用SPSS统计分析软件,用主成分分析方法对 PH 值、溶解氧(DO)、高锰酸盐指数(CODMn)、生化需氧量(BOD)、氨氮(NH3-N)、总磷(TP)、铅(Pb)和汞(Hg)等水质指标进行分析处理,识别主要污染因子,得出影响清水河流域水质污染的主要限制因子为 PH、溶解氧、高锰酸盐指数、生化需氧量、氨氮,为清水河流域针对性水质预测、水质污染控制、水资源利用和清水河流域可持续发展提供依据.%Based on the monitoring data of water quality during the year 2012-2015 in Laoyaozhuang and Beibengfang monitor section of Qingshui River,which is the interior-view river of Zhangjiakou City,by means of SPSS statistical analysis software,the principal component analysis was used to analyze and evaluate such water quality indicators as pH value,dissolved oxygen(DO),permanga-nate index(CODMn),biochemical oxygen demand(BOD),ammonia nitrogen(NH3-N),total phos-phorus(TP),lead(Pb)and mercury(Hg).The major pollution factors were identified,in which the main limiting factors affecting the water quality pollution in the Qingshui River Basin are PH, DO,CODMn,BOD,and NH3-N,providing the basis for Qingshui River Basin in terms of water quality predictions,water pollution control,water resources utilization,and sustainable develop-ment.
