摘　　要：在分析传统决策支持系统在城市规划决策应用中存在的问题的基础上 ,初步提出一种基于数据仓库的城市规划决策支持系统的基本框架 ,探讨了该系统建立中数据仓库的数据组织、数据挖掘、知识发现方法等关键技术问题 ,并进一步阐述城市规划决策支持系统的建立方法 ,最后以荆州市环境规划为例 ,说明数据仓库在城市规划决策支持系统中的具体应用。Under the urgent requirements of information development,research on data warehouse is now raising and becomes a new international frontier research direction.Firstly,the paper analyzes some problems in traditional urban planning decision support system,that is:(1)This system can only provide with data support of aided planning decision,but without semi_structured decision problems if traditional database techniques are used.(2)Integrated data are the basis of decision support system,however,it is not easy to integrate data which distribute in varied heterogeneous data platform.(3)If the decision support system is established on the basis of database management system,the ability of spatial problem of knowledge expression and knowledge synthesis will be not very strong because of weak calculation ability of database.Secondly,the paper presents preliminarily system architecture of urban planning decision support system based on data warehouse.The system consists of database,planning data warehouse,database warehouse management module,data mining tool,knowledge base,knowledge discovery module and user interface.The key problems are how to create planning data warehouse,how to discover knowledge from data warehouse,and how to apply knowledge discovered to the practice.Thirdly,the paper discusses organization of planning data warehouse,data mining techniques and methods of knowledge discovery.Data in urban planning and management come from basic geographical information,planning results,and so on.The planning data warehouse can be divided into three levels: historical data level,synthesized data level and special data level.The historical data level is used as urban trend analysis and urban simulation.The synthesized data level includes varied statistical data,planning control index,evaluation results and forecast analytical data.The special data level stores data of population,resource,economics,environment,and some parameters in mathematical models,prediction models and evaluation models.The planning data warehouse
