摘要
空间决策支持系统是在G IS和决策支持系统基础上应运而生的面向空间问题领域的决策支持系统,适用于资源评价领域。提出建立土地适宜性评价空间决策支持系统的思路,该系统由数据库系统、模型库系统、方法库系统、知识库系统和人机接口五部分组成,具有数据输入与输出、图属互查、空间分析、辅助决策等功能。同时还探讨了土地适宜性评价空间决策支持系统的实现途径。
Spatial decision support system is a spatial object- oriented decision support system, based on GIS and DSS, which can be applied to resource evaluation. This paper points out a spatial decision support system for land suitability evaluation. The system is made of database system, model storehouse system, method storehouse system, knowledge storehouse system and man -machine interaction surface, and has function of data input and output, query between map and attributes, spatial analysis, decision aid, and so on. The way to establish the system is suggested also.
