大沽河流域农田径流污染研究

Study on the Farmland Runoff Pollution in Dagu River Valley

重点对大沽河流域的农田径流污染进行了研究,通过选定典型区域进行农田径流实验研究,计算出农田径流源强系数,为农田径流非点源污染研究提供计算参数;引用承担的《大沽河流域水环境承载力与污染防治对策研究》课题中对其他污染源的计算结果,对农田径流污染在整个流域中的分担情况进行了分析,结合计算的水环境容量,确定大沽河流域污染物消减指标,制定污染防治对策,为"环湾保护、拥湾发展"服务。

Farmland runoff pollution in Dagu River valley is emphatically studied in this paper. To make an analysis of actual situation of the valley combined with rainfall experiment, the index of source strength of runoff is calculated. The calculated index could provide a reference for the research of farmland runoff pollution in Qingdao area. Taking account of the calculated results of other pollution source in the project ＂Study on the water environment carrying capacity and countermeasures,against pollution protection in Dagu River valley＂, the analysis of the sharing status of farmland runoff pollution in the whole valley was conducted. Combined with the calculation of water environmental capacity, the reduction target of contamination in the Dagu River valley and protection and cure measures were set down, which could work for the stratagem of ＂Rounding Protection and Development of Jiaozhou Bay＂.
