基于生产-消费模型的"数字城市"信息共享方法研究

城市信息资源共享是“数字城市”建设的关键问题。在总结城市信息资源共享现状和存在的问题基础上,从信息生产—消费关系的角度分析城市信息资源共享,提出基于生产—消费模型的“数字城市”信息资源共享方法。该方法充分考虑了城市信息资源共享的内在特点,可以提高城市信息资源共享的效率,满足“数字城市”建设需求。在此基础上,给出该方法的技术解决方案。

Research on Information Sharing of Digital Cities Based on Production-Consumption Model

Information sharing is the key of construction of digital city.Based on the summarization of the status and the problem of information sharing,a method of information sharing in the digital city system is presented in this paper,based on production-consumption model from the point of view of the production-consumption relationship.The method takes the inherent characteristics of the city information resource sharing into account adequately,which can ultimately improve the efficiency of the city information resource sharing and fully meet requirement of the construction of digital city.Finally,technological solution of the method is presented.
