摘要
以漳河流域为研究区域,建立SWAT模型对面源污染进行模拟分析,对该地区污染控制提供依据。根据水文站1960~2014年的实测数据,对模型进行率定和验证来模拟研究与分析。该模型对漳河流域的适合性较强,可用于该流域的面源污染的模拟研究。对污染负荷分布规律进行分析表明,污染负荷与该区域降雨量、坡度、土壤侵蚀性和农业生产有着密切的关系,控制面源污染关键在于减少流域内的水土流失,降低土壤养分流失、减少农业用肥量和加大绿化带面积可有效控制该流域的面源污染。
This paper simulated the non - point source pollution in Zhang River Based on SWAT Model to provide basis for pollution control. The model verified use data from 1960 to 2014 at hydrological stations. The non -point source pollution model had good adaptability in the study area, and can be used for simulation research of non - point source pollution. Pollution loading has a close relationship with rainfall, slope, soil erosion and agricultural production. The appropriate measures for controlling non -point source pollution in Zhanghe River Based are reducing soil erosion, loss of soil nutrients and increasing green belt area.
