流域面源污染关键区快速识别方法的研究与应用——以海河干流流域为例

摘要

This study chosen Haihe River Basin strongly influenced by anthropogenic activities.On the basis of multi-factor comprehensively considering,a relatively simple spatial evaluation model has been developed through simplifying the complicated mechanism model.The new model was formed by combining with "source-transportation" framework and GIS technology,which can give a rapid and practical assessment method of identifying the potential non-point source loss risk to environmental regulators.And then it will provide guidance for similar research areas.%选择了一个下垫面受人类活动影响剧烈的研究区域——海河干流流域作为研究对象,在综合考虑多种影响因素的基础上,对复杂的模型进行简化,形成一种基于"源-汇"框架以及地理信息系统(GIS)技术的流域面源污染快速评价模型,旨在为水环境管理者提供一种快速甄别流域面源污染潜在风险的方式,为贫数据研究区域的相关研究提供借鉴.
