基于WebGIS的农业面源污染信息系统的开发及应用

农业面源污染研究是当前国内外环境科学与工程领域的研究热点,但研究大多侧重于农业面源污染的成因、机理、模型和控制对策等,而缺乏一个良好的交互式的用户界面来发布、管理和分析农业面源污染,使其可视化等.本文以太湖流域的杭嘉湖平原为例,通过利用GIS及其相关技术,特别是WebGIS技术(ArcIMS、ArcSDE)的应用,建立了一个基于WebGIS的农业面源污染信息系统(ANPSPIS),以期为农业面源污染的管理、规划和决策提供依据.

Practise and application of agricultural non-point source pollution information system based on WebGIS

At the present ,the research of ANPSP is an interesting topic in envir onmental science and engineer fields.However,almost all the jobs in this field w ere limited to the cause of formation and the model and control measure,and lac ked for a good interface to complete the publication and the management and the analysis and the visualization of ANPSP.With a case of Hang-Jia-Hu Plain of Ta iH u Basin in the paper,Utilizing the GIS technique adequately, especially the app lication of WebGIS technique(ArcIMS?ArcSDE),this experiment has established a agricultural non-point source pollution information system(ANPSPIS) based on W e bGIS.It provides the reference for the management and programming and decision- making of ANPSP.
