摘　　要：采用改进的内梅罗污染指数法和Mann-Kendall非参数检验方法,评价了金堤河主要水质指标时间与空间变化趋势,探讨了流域管理和河道整治措施对金堤河水质的影响。结果显示,近年来金堤河水质总体属Ⅳ类,少数断面为III类,主要污染物为总氮、总磷。近年来金堤河流域生活污水、工业废水等点源污水处理措施对降低有机类和石油类、挥发酚类点源污染具有显著成效,但对治理总氮总磷污染效果不显著。因此,控制流域氮磷农业面源污染、改进污水氮磷处理工艺是进一步控制金堤河氮磷污染的必要措施。Using the improved Nemero comprehensive pollution index method and Mann-Kendall non-parametric test method,the temporal and spatial change trend of the main water quality indicators of the Jindi River are evaluated.The impact of watershed management and river regulation measures on the water quality are discussed.The results show that the water quality of the Jindi River generally belongs to class IV,and a few sections are class III,and the main pollutants are total nitrogen and total phosphorus in recent years.In recent years,the point source sewage treatment measures of domestic sewage and industrial wastewater in the Jindi River Basin have achieved remarkable results in reducing the point source pollution of organic,petroleum and volatile phenolics,but have no significant effect on the treatment of total nitrogen and phosphorus pollution.Therefore,it is necessary to control the nitrogen and phosphorus non-point source pollution and improve the sewage nitrogen and phosphorus treatment process to further control the nitrogen and phosphorus pollution in the Jindi River.
