阿什河流域非点源污染优先控制区识别

ASHLEY River Basin Non-point Source Pollution Control Priority Identification

由于农村生活污水排放及化肥的过度施用,大量的污染物进入河流,对环境造成严重污染。为寻找到污染较严重的区域并进行有针对性的治理,运用美国农业部开发的SWAT模型及美国地质勘探局(United States Geological Survey,简称USGS)开发的LOADEST模型,对研究区的污染物进行估算及模拟,并采用空间分析方法获得污染物优先控制区。结果表明,污染物的模拟效果较好,通过空间分析可以有效识别污染严重的区域,为未来阿什河流域环境的综合治理提供借鉴。

Because of rural life sewage and the excessive use of fertilizers,a large number of pollutants into the river,caused serious pollution to the environment,in order to find the pollution is more serious areas targeted governance,this paper USES the United States department of agriculture development of SWAT model and the U. S. Geological Survey（ United States Geological Survey,or USGS） LOADEST model of development,has carried on the estimation and simulation of pollutants in the study area,and the spatial analysis method for priority control pollutants,results show that the simulation effect is good,pollutants through spatial analysis can effectively identify the polluted area,for the future through this analysis method can be reference for comprehensive control of river basin environment.
