摘要
调查评价白洋淀流域农业面源污染状况,采用经验统计的方法估算农业面源污染负荷。分析了农业面源污染对白洋淀流域水环境的影响,可使河流水质变差,水库出现富营养化,地下水采中硝酸盐氮浓度升高,甚至威胁到人们的饮水安全。最后提出了农业面源污染控制措施。
The status of agricultural non-point source pollution in Baiyangdian Basin was investigated and evaluated,the statistical experience method was adopted to estimated the load.The influence of agricultural non-point source pollution to the water environment in Baiyangdian Basin was analyzed.It can cause deterioration of water quality of rivers,eutrophication of lakes and reservoirs,exaltation of nitrate concentration in groundwater,it even can threaten people＇s drinking water safety.Finally,the control measures of agricultural non-point source pollution were proposed.
