摘要
农业面源污染日渐严重,对人类生存环境的影响不容忽视。综述了农业面源污染的危害与现状,并详细介绍了植生滤带削减农业面源污染传输的原理,分析了植生滤带在不同环境条件下尤其是地下水水位波动对农业面源污染削减效率的影响。VFSMOD模型已被美国环保署推荐为可应用于流域规划植生滤带并有效评估其削减面源污染效率的模型,详细阐述了VFSMOD模型的机制、功能及全局敏感性和不确定性分析,并针对植生滤带及VFSMOD模型的模拟技术提出了今后进一步完善的方向及研究展望,可为农业面源污染的管理与防治提供参考。
The increasing discharge of agricultural nonpoint source pollution strongly influences the watershed environment.This study summarizes the present situation and hazards of the agricultural nonpoint source pollution.The major factors especially the groundwater table influencing the reduction efficiency of agricultural nonpoint source pollution in Vegetative Filter Strips(VFS)are discussed.Vegetative Filter Strips MODel(VFSMOD)has been listed by USEPA as one of the models to evaluate the performances of the management practices in VFS for protecting watershed environment.The study expounds the mechanism,functions,global sensitivity and uncertainty analysis of VFSMOD,and finally points out the future research prospects to provide reference for the management of agricultural non-point source pollution.
