摘　　要：本文简要介绍当前网络三维GIS的研究进展。设计具有数据层、发布层和应用层的三层网络三维GIS框架,进一步阐述基于Skyline软件体系实现该框架的技术路线,并详细说明建设的具体步骤:数据采集、数据处理、系统开发和发布与部署。并且针对实际建设过程,从三维建模、模型显示、数据加载和缓存设置四个方面提出相应的优化措施。This paper introduced current researches on Web 3D-GIS in brief. After that, the paper designed a three-tier architec- ture for Web 3D-GIS, which includes data tier, publishing tier and application tier. According to it, the technical route based on Skyline software was elaborated. Moreover, the paper showed the specific construction steps that are data acquisition, data processing, system development and release ＆ deployment. Then, some measures to optimize actual construction process in terms of 3D model building, model displaying, data loading and cache setting were provided. At last, a lot of disadvantages as deficient expansibility, huge difficulty of data update and nonsupport for spatial analysis were pointed out by analyzing the practical application case. The paper claimed that the development direction and trend of Web 3D-GIS could be to apply the standard of HTML 5 and 3D structure feature, which would promote the progress of 2D ＆ 3D integration.
