基于GIS的赣州市宋代排水系统的数字化重现与新城区防涝强度评价研究

内涝问题是现代城市的一大通病。赣州市章贡区的老城区素有“千年不涝”之美誉,而与老城区一江之隔的章江新城区的建成区却存在内涝问题。为探究赣州老城区“千年不涝”之谜,为章江新城区的排水系统规划修编提供指导性意见,在对赣州老城区排水系统进行数字化重建的基础上,对排水系统的防涝强度评价指标进行分析研究,并与章江新城区的排水系统规划进行了分析比较,提出了章江新城区雨水系统规划修编的建议。

Waterlogging problem is a common problem in modern city.The old urban area of Zhanggong District of Ganzhou city was praised as"Millennium no waterlogging".The built-up area of Zhangjiang new urban area,which is separated from the old urban area by the river,also has the problem of waterlogging.In order to explore the mystery of"Millennium no water-logging"of old urban area of ganzhou,guiding opinions were put forward for the revision of drainage system planning in Zhangjiang new urban area.On the basis of digital reconstruction of drainage system in ganzhou old urban area.The evaluation index of waterlogging prevention intensity of drainage system is analyzed and studied,and compared with the drainage system planning of Zhangjiang new urban area.Suggestions are put forward on the revision of urban rainwater system planning in Zhangjiang new urban.
