基于GIS的区域土壤资源管理决策支持系统

传统的地理信息系统 ( GIS)在土壤资源管理上的应用存在着许多不足之处 ,如功能上的缺陷 ;系统过于庞大复杂 ;缺少灵活性等 .随着信息技术的发展 ,传统的 GIS已很难适应不断发展的土壤资源管理的需求 ,于是决策支持系统 ( DSS)就应运而生了 .该研究提出了一个基于 GIS的土壤资源管理决策支持系统 .该系统由数据库及其管理系统、模型库及其管理系统、方法库及其管理系统及人机交互系统组成 .系统可为土地利用适宜性评价提供多种决策方案 ,且为不同层次的决策者服务 ,弥补了传统的 GIS和单一的 DSS的不足 .

Decision Support System of Regional Soil Resources Management Based on GIS

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. This system is made of database and its management system, method storehouse and its management system, model storehouse and its management system and man-machine interaction system. The system can be used to offer various decision schemes for land suitable appraisement and planning, and to serve for different level policymaker. It makes up the lacks of traditional GIS and unitary DSS.
