摘　　要：采用一种全新的水质指数对丹江口水库及入库支流19个监测站点的水质监测数据进行分析和评价,得出入库支流中主要污染河流为神定河、泗河、犟河、剑河、浪河、老鹳河,主要污染指标为粪大肠菌群、氨氮、总磷、溶解氧等.库区与其他入库支流水质状况良好,除粪大肠菌群之外,其他指标监测值基本满足Ⅰ类水标准限值要求.在SPSS软件中运用主成分分析法对主要污染指标进行相关性分析,得出主要污染指标两两相关性较好,很可能来自同一污染源.This thesis analyzes the water quality data of 19 monitoring stations in Danjiangkou Reservoir with a new water quality index.And it is concluded that the main polluted rivers are Shending river,Si river,Jiang river,Jian river,Lang river and Laoguan river,and the main pollution indicators are fecal coliform,ammonia nitrogen,total phosphorus,dissolved oxygen,etc.In addition,water in the reservoir and other tributaries are in good condition,except for the fecal coliform,the monitoring values of other indicators are all under the class I water standard limit.Meanwhile,a principal component analysis is conducted by SPSS software,and in conclusion that the correlation between the main pollution indicators is strong,probably coming from the same pollution source.
