Environmental Decision Support System Development for Soil Salinization in the Arid Area Oasis

Soil salinization is a mayor problem for agriculture and soil conservation, which often bring the environmental problems and economic loss, especially in arid and semi-arid areas, such as in the southeast margin of Tarim Basin in Xinjiang, China. The results of study indicated that the increase of water table was the main cause resulting the increase of soil salinity. Utilization of water resources and control of groundwater play a key role to resolve the problem. This paper provides an overview of the development and implementation of an integrated environmental decision support system (EDSS) designed to help policy makers and other stakeholders have a clearer understanding of the key factors .The EDSS is developed based on the mathematical compute soft which solve the muti-object models and geographic information system (GIS) which support spatial management .It provides visual simulation environment and scenario water recourse management and analysis capabilities. Some lessons drawn from development of the system are useful for other in arid and semi-arid areas for management of water resource.
