Abstract:

Watershed environment management has been an important research field for environment science，and the groundwater quality assessment is an important content for the water resource sustainable development management and strategic environment assessment on watershed，the methods are needed to support it.The research level about the integration of GIS and models was fully analyzed at home and aboard，the needed items and advantage were narrated for the integration between GIS and integrated index models and mechanic models.It is emphasized that characteristics，inputs and outputs of model，watershed basis data and functions of GIS software in the integrated process，or else the regional analysis difference will be enlarged，even the error information may be emerged.The integration framework is put forward based on the general index model and mechanic model，the three models in the process of integration is analyzed，and the developing trend is pointed out.Finally the decision is put forward to avoid the disadvantage in the integration of GIS and models，the priority methods and suitable items are acquired for the integration between integrated index models and mechanic models，which can be used as a guide for application.
