上海浦东新区外环以内排水(雨水)防涝综合规划研究

随着城市化进程的快速推进和极端天气的增加,影响城市安全的内涝问题日益受到公众关注。浦东新区位于上海市东部,河道分布不均,呈现南密北疏、中心城外密中心城内疏等特点,传统的排水规划已经不能完全满足现状城市安全的需要。结合城市特点,浦东新区排水防涝规划坚持“绿灰蓝管”多措并举的理念,深度挖潜现有设施,合理解决好源头控制与大、小排水系统的组合问题;通过构建模型评估城市内涝风险、高效预测区域积水灾害、明确重点提标改造地区,有效提升规划效率并及时反馈规划效果。规划通过对已建系统进行低影响开发及现有排水设施多用途利用等方式对排水系统进行提标改造,有效提升城市排水防涝能力,可为今后同类规划的编制提供参考和借鉴。

Research on Integrated Planning of Drainage (Rainwater) and Waterlogging Control within the Outer Ring of Pudong New District in Shanghai

With the rapid promotion of urbanization and the increase of extreme weather, the waterlogging problem affecting the urban safety is attracting the increasing public attention. Pudong New District is located in the eastern part of Shanghai with the uneven distribution of river channels, showing the characteristics of dense in the south and sparse in the north, dense outside the center and sparse in the center. The traditional drainage planning has been unable to fully meet the need of the current urban security. Combined with the characteristics of the city, the drainage and waterlogging control planning of Pudong New District adheres to the concept of "green-gray-blue" measures to explore the existing facilities deeply and reasonably solves the problem of source control and the combination of large and small drainage systems. By building a model to assess the risk of urban waterlogging, efficiently predict the regional flooding disasters and clarify the focus on upgrading and reconstructing the areas, the planning efficiency can be effectively improved and the planning effect can be timely fed back. The drainage system is upgraded and reconstructed by means of low-impact development of the existing system and the multi-purpose utilization of the existing drainage facilities. The ability of urban drainage and waterlogging prevention has been effectively improved, and some references are provided for the preparation of similar planning in the future.
