基于非点源污染负荷模型PLOAD的最佳管理措施模拟研究

Simulation study on best management practices built-in PLOAD

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.

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 priori ty, 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.
