摘要
农业生产和农村生活污水是香溪河水体氮磷污染的主要来源,控制农业面源污染是防控三峡库区水体,特别是支流水体富营养化的重要任务和措施。结合香溪河流域自然环境、经济社会和农业生产结构等特点,分析其农业面源污染现状并提出有针对性的农业面源污染防控措施,实现了三峡库区小流域农业面源氮磷流失"控源"、"截汇"和"治污"的管理体制有机结合,旨在为三峡库区小流域氮磷管理提供科学的理论依据,为库区农业面源污染控制提供技术支持。
Agricultural production and rural domestic sewage are the main sources of nitrogen and phousphorus pollution of water body in Xiangxi River Watershed（ XXRW）. It is an urgent task and important measure to control agricultural non-point source pollution for preventing eutrophication in water body of Three Gorges Reservoir Area,especially in some tributaries. According to the characteristics of natural environment,social economic and agriculture production structure,this paper analyzed the current situation and control management of agriculture non-point source pollution in XXRW. Agricultural non-point source pollution control should be integrated with the management system of source control,intercepting pollution,and pollution treatment in small watershed of Three Gorges Reservoir Area to provide a scientific basis and technical support for management of nitrogen and phosphorus.
