摘要
传统的基于GIS建立的土地适宜性评价系统缺乏对空间问题决策的支持能力,而GIS与DSS技术集成建立土地适宜性评价决策系统一方面可以实现对空间数据的管理和分析,另一方面可以利用模型进行辅助决策,有利于解决与空间有关的决策问题。以MapInfo Professional 6.0为基础平台,以Visual C++6.0为开发工具,建立了一个土地适宜性评价决策支持系统,该系统包括数据库系统、模型库系统、知识库系统以及人机接口4个部分,具有数据输入输出、图属互查、数据空间分析和辅助决策等功能。系统成功应用于南京市江宁区淳化镇农地适宜性评价实践中,应用结果表明系统能为决策者提供多种决策方案,同时又集成了GIS的数据管理和空间分析功能,满足土地适宜性评价的要求,有推广使用的价值。
Traditional land suitability evaluation system based on GIS is deficient in supporting the decision of spatial issues, while integration of GIS and DSS in land suitability evaluation system can both manage spatial data and assist decision by using relevant models. With Maplnfo Professional 6.0 as the platform and Visual C^＋＋ 6.0 as the developing tool, a land suitability evaluation system based on GIS and DSS is developed. It is made of database system, model base system, knowledge base system and man-machine interface, and has functions of inputing and outputing data, querying between map and attributes. It can also analyse spatial data~ assist decision, and so on. The system is successfully applied in land suitability evaluation of Chunhua County, Jiangning District, Nanjing City.It is indicated that the system can provide several decision models to be selected, and integrate functions of data management and spatial analysis. It meets the need of county-level land suitability evaluation, and has values being popularized.
