基于WebGIS的农业面源污染信息系统的开发及应用

Practise and application of agricultural non-p oint source pollution information system based on WebGIS.

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We-bGIS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。

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.
