Abstract  Geoprocessing service not only provides common function of GIS spatial data analysis,but also supports establishing complicated geoprocessing model and publishs the model as Web services,function of spatial data analysis and sharing ability is improved.This paper taking the Qinwangchuan basin in Lanzhou New Area as the study region,according to DRASTIC model groundwater vulnerability evaluation method,each evaluation factor score of the model is determined.The weight value of each evaluation factor is determined with the analysis hierarchy process method.A groundwater vulnerability assessment geoprocessing model for the study region is established by ModelBuilder visual modeling environment in platform of ArcGIS,geoprocessing model is published on web by ArcCatalog,Web client application of geoprocessing service is established with ArcGIS API for JavaScript.The groundwater vulnerability assessment map of the Qinwangchuan basin in Lanzhou New Area is automatically established by calling the service in client.Network sharing of groundwater vulnerability assessment is realized,complexity and workload of assessment map establishing is decreased.A new way of extensive application of groundwater vulnerability assessment model is provided.
