城市规划三维决策支持系统设计与实现

Design and Implementation of 3D Decision Support System for Urban Planning

随着中国城市化进程的加快,城市建设面临日益复杂的空间关系与空间决策,特别是建设项目的规划决策不断影响着城市环境的协调性,基于二维平面图和效果图的规划决策已不能满足城市管理的需要。提出了建立真实现状三维环境和真实虚拟规划模型相结合的技术方法,研究了多种三维空间分析技术,开发了实用的系统,并投入工程化应用,取得了良好的效果。

With the accelerated process of urbanization in China,urban development is facing increasingly complex spatial relations and spatial decision,in particular the project＇s planning decisions continue to affect the coordination of the city＇s environment,based on 2D floor plan and rendering of planning decisions already cannot satisfy urban management needs.According to 3D GIS,the technical methods of real 3D environment and virtual planning model combining is put forward,a variety of 3D spatial analysis technique is studied,the system is developed and put into practical application of engineering.
