基于Geodatabase的北京城市污水规划辅助系统的开发与应用

Development and Application of Geodatabase based Auxiliary Urban Wastewater Planning System

第三代空间数据模型 (Geodatabase)以ArcInfo作为应用平台 ,充分利用ArcInfo平台的空间分析功能和Geodatabase关系数据库的属性查询功能辅助城市污水系统规划。系统在北京城市污水处理厂合理布局规划上得到应用 ,其在自动化程度和方案生成效率等方面 ,已经被证明优于传统的城市规划工程平台CAD。

This system was developed on the basis of the 3rd generation spatial data model Geodatebase, and the ArcInfo was applied as its application platform. Both the spatial analysis function of ArcInfo and the attribute query function of relational database are sufficiently utilized in this system. As the assistant platform, this system has multi functions related to urban wastewater planning in Beijing, such as the partitioning drainage watershed, defining service region and estimating the capability of wastewater treatment plants, laying the wastewater and reclaimed water pipelines, calculating the amount of gray water reusing, computing cost of different planning scenarios, and displaying different scenarios etc. In the project, the system is proved to be more automatic and efficient than that of CAD data model, which is the traditional urban engineering plan platform. It is believed that such system would be a new means to solve the urban engineering plan issues, and it will have a broad foreground.
