【摘要】 提出了一种分级选择控制区,以确定流域内重点非点源控制区并实施最佳管理措施的优化方法.首先利用PLOAD模型计算流域非点源污染负荷量,并筛选出重污染区,最后模拟在重污染区中实施生态工程措施后的效果,为最佳管理措施的选址与实施提供依据.更多还原

【Abstract】 Proposes a kind of optimized method to confirm the pollution control priority of watersheds in study area.Firstly,PLOAD model was induced to calculate the non-point pollution load,which was proposed by EPA. Secondly,in order to figure out sub-watersheds that holding pollution control priority,a priority check was carried out by comparing the maximum non-point source pollution loads from sub-watersheds.Finally,the effect of some ecological engineering BMPs implemented in the priority sub-watersheds was simulated.更多还原
