摘要
农业面源污染现象复杂,且在空间处理和可视化方面受限,而GIS在这2个方面有独特的优势,因而被迅速应用到面源污染研究中,且取得了良好的效果。从数据库技术、数据处理、与模型集成、信息系统开发、可视化表达等几个方面总结了GIS技术在农业面源污染研究中的应用,同时总结了研究的热点,并对WebGIS和ComGIS在农业面源污染研究中的应用趋势进行了展望。
Agricultural non-point source pollution, whose phenomenon is complex, is restricted in terms of spatial processing and visualization, in which GIS has a unique advantage. Therefore,GIS is applied to the study of non-point source pollution,which has achieved a good result.The application of GIS in the study of agricultural non-point source pollution in the aspects of database technology,data processing, model integration, information system developing,visualization expression and so on were summarized,and the focuses of current research and the prospect of the application of WebGIS and ComGIS of agricultural non-point source pollution was summed up.
