Practise and application of agricultural non-p oint 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.
