基于GIS的区域土壤资源管理决策支持系统

Traditional geography information system (GIS) on soil resource management application has a lot of insufficient departments, for example, the defect on function; too huge and complex in system components; lack of flexibility etc. Along with the development of information technology, the traditional GIS is difficulty to met the demand of the soil resource management of unceasing development, so decision support system (DSS) are pregnant. This paper points out a decision support system for soil resource management based on GIS.
