摘要
城市排水管网规划管理的GIS系统WPPMS-GIS是利用MapInfo的二次开发工具MapBasic和VisualBasic语言将MapInfo地图窗口集成到VB程序中而开发出来的应用程序。该系统将排水管网的空间数据与属性数据分别存储于MapInfo表和Access数据库中,编写程序将两者连接起来并实现预定功能。水力计算模块是WP-PMS-GIS系统的一个重要的组成部分,采用GIS环境下建立的排水管网优化设计的数学模型,主要包括排水管网的直接优化法以及排水管网和排水管网设计流量的递归算法。WPPMS-GIS在广东省佛山市镇安片区排水管网的应用实例证明其实用性,实现了预定功能。
Wastewater pipe-net planning and management system under GIS（WPPMS-GIS） is an application integrating Maplnfo map windows into Visual Basic program using MapBasie and Visual Basic. In this system, the spatial data and attribute data of drainage pipe-net are storaged separately in MapInfo tables and Access database. They can be linked by program and provide some special function. As an important component in WPPMS-GIS,the hydraulic calculation module is based on the mathematic model of optimum design under GIS,ineluding direct optimization method for drainage pipe-net and reeursive algorithm for pipe-net and pipeline designed-discharge. It proves that WPPMS-GIS is effective with the application on the wastewater pipe-net of Zhen-an district in Foshan city of Guangdong province.
