针对汉江中下游农业面源污染的需求，以野外观测数据为基础，结合地理和农业环境基础数据，设计开发了农业面源污染信息系统，并结合地理信息系统和数学模型对汉江中下游农业面源污染负荷及其空间分布进行了研究。
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.
