摘要
由农业产生的非点源污染是湖泊的主要污染源。为了研究太湖流域非点源污染负荷流失规律,选择了宜兴梅林小流域为研究对象,对降雨过程中径流流量及其污染物浓度随降雨—径流变化过程进行了监测研究。采用统计和系统分析方法,建立径流量和非点源污染负荷输出量之间的数学统计模型,得出该流域非点源污染物流失规律,以期将此方法推广到与该流域相似的其它地区的非点源污染研究中去,对太湖流域水污染综合治理也具有重要意义。
The non-point pollution emerged in agriculture production is the main pollution sources of lake. In order to research the non-point pollutant losing law in Taihu lake basin, Meilin small valley in Yixing city of Jiangsu province was selected as a research object to carry out monitoring and researching on the variation process of runoff rate and pollutant concentration along with the rainfall-runoff course. The statistical and systematic methods were used to set up mathematic statistic model between runoff rate and output of non-point pollutant load output, and the non-point pollutant losing law in the valley was obtained. The research achievements in this research can be used in non-point pollution research in other similar valley and possess important significance in comprehensive water pollution control in Taihu basin.
