摘要： 分析了传统WebGIS开发技术的缺陷，以上海市超限高层建筑工程实例为背景，提出了一种基于J2EE平台架构的ES-SDGIS系统，有效地解决了现有系统并发访问能力不强、耦合度太高、兼容性差、开发部署困难等问题，并融合了模糊推理功能。讨论了系统组件设计、模糊推理中知识库的知识划分以及知识表示、综合模糊评判模型、Web条件下Matlab应用程序的调用等关键技术。

Abstract: The deficiency of the current WebGIS is analyzed, and a new ES-SDGIS is provided using J2EE technology based on the instances of out-of-code buildings in Shanghai. Problems such as inefficient compatibility, complicated development and distribution, and tight coupling are solved within the system; also the fuzzy inference function is added. This article discusses the component design, knowledge class and expression, synthesis fuzzy evaluation model, and the Matlab program calling under the Web.
