辽宁省海城市化肥面源污染评价

Evaluation on the Non-point Pollution of Fertilizer in Haicheng

针对辽宁省海城市面源污染严重的现状,通过对全地区化肥产生的源头进行调查分析,计算出各地区面源污染的负荷量,同时采用等标排放量和等标排放指数等对污染物进行综合分析评价,利用GIS进行污染区划,明确了海城市化肥污染发生的空间分布规律,并提出了相应的污染控制对策。

Based on the serious situation of the non-point pollution in Haicheng City in Liaoning Province,and through investigating and analyzing the source of chemical pollution,the non-point pollution loading of each area was calculated.Then the equivalent standard pollution loading and index of pollutants were adopted to evaluate the pollutants comprehensively,GIS was used for pollution division,so as to made clear the spatial distribution of chemical fertilizer pollution in Haicheng and put forward corresponding pollution control measures.
