| 中文摘要: |
| 利用GIS对空间数据进行处理和分析的功能，建立雨水管网达标规划GIS系统，实现了雨水管网设备的属性数据及空间数据的一体化管理，为城市暴雨积水计算提供可视化分析的手段；同时，建立了汇水区的达标体系，并可以动态划分调整汇水区，计算分析城市各汇水区在不同降雨条件下的积水状况；对不符合要求的管网提出可行性设计建设方案。最后以南京市为例，分析了该市主城区雨水管网系统，为管网的规划及防洪排洪提供了决策支持手段。 |
| 英文摘要: |
| The spatial data processing and analyzing functions of GIS technology are utilized to establish the GIS system of pipeline network planning for rainfall drainage. It provides the method of visualized analysis on urban retaining water due to rainstorm. At the same time, a standard index system for discriminating the pipeline network whether it met the requirements or not is established. The retaining area is divided into several parts for dynamic dispatching of drainage according to the requirements. The retaining situation under different conditions of rainfall can be visually analyzed. This method is applied to analyze the planning of the drainage pipeline system in Nanjing City. |
