城市土地可持续利用评价SDSS的研究

Research on the Spatial Decision Support System for Evaluation of Sustainable Urban Land-Use

为促进城市土地可持续利用评价的应用,研究开发城市土地可持续利用评价空间决策支持系统。系统以决策支持系统架构集成GIS来实现空间支持能力,基于Composite模式设计评价决策模型,以可动态扩展的方式实现了多种评价分析方法并优化了评价的流程,此外还实现了土地利用空间结构分析功能。实际应用表明,系统对提升城市土地可持续利用评价的效率及准确性和可靠性有突出的效果。

To promote the application of the evaluation of sustainable urban land-use, a Spatial Decision Support System for Evaluation of Sustainable Urban Land-Use was designed and built. The system integrated GIS to support spatial problems based on the structure of decision support system. The evaluation support model was designed based on Composite design pattern. The methods of evaluation were implemented as dynamic link library. The process of the evaluation was optimized by the system. And the system also implemented the functions for analyzing the spatial structure of land-use distribution. The application of the system shows that the system has significant effects on improving the efficiency, accuraey anti reliability of the evaluation.
