摘    要:根据汉江中下游农业面源污染治理决策的需求,在大量实地观测资料区域地理与农业环境数据基础上,开发并建立了汉江中下游农业面源动态监测信息系统。以此为技术支持,运用数学模型及其与GIS相结合的技术,研究了汉江中下游农业面源污染的负荷及分布规律。

关 键 词:GIS  汉江中下游  农业面源污染  氮磷负荷  地理信息系统  水域污染

Abstract:According the requirements of agricultural non-point source (AGNPS) pollution in middle and lower reaches of Han River, the agricultural non-point source pollution information system was designed and developed based on observing data in the field and the basic geographical and agricultural environmental data.By this system, the load and spatial distribution of agricultural non-point source pollution with integrating GIS and mathematical model in middle and lower reaches of Hanjing River were researched.
Keywords:agricultural non-point source pollution  load of nitrogen and phosphorus  geographic information system
