| 摘 要： | 根据1991～2006年16年的水质监测数据，选取高锰酸盐、氨氮、溶解氧3项指数，运用单因子指数、综合指数评价方法对白河流域水质进行分析，通过水质的逐月变化及逐年变化比较，探索白河流域水质时程变化特征，同时结合秩相关系数法（Spearman）对水质趋势进行分析，最后提出保护建议措施：

| Abstract: | Based on water quality monitoring data from 1991 to 2006,CODMn,NH3-N,and DO were chosed to analyze Baihe waters water quality using single index and comprehensive index.Comparing the monthly change and yearly change of water quality,the Spearman rank correlation coefficient of data was calculated and its tendency was analyzed.Finally,the suggestions for river protection were put forward. |
