Enlightenment of Tangpu polder water conservancy system in Taihu watershed to sponge city

当前海绵城市建设逐渐进入攻坚和扩大阶段,全国各地建设成效初显的同时也暴露出不少问题。塘浦圩田是太湖流域独特的农田水利工程,在区域防洪排涝、调蓄灌溉、生态环境等方面发挥重要作用。它是中华民族治水智慧的集大成者,其中蕴含的治水技术和工程哲学与当代海绵城市建设理念非常吻合。从空间格局、蓄排系统、治水思想等方面分析塘浦圩田水利体系中蕴藏的雨洪管理智慧,总结值得海绵城市建设借鉴的思路和方法,为后续建设提供有益的启示。

The development of sponge city has gradually entered a critical stage. Although fruitful results across the country have begun to appear, there have been many problems. Tangpu polder is a unique farmland water conservancy project in the Taihu watershed. It plays an important role in regional flood control and drainage, regulation and storage of water, irrigation, and ecological environment protection. It assembles the characteristics of traditional wisdom of water treatment, and its water-control technology and engineering philosophy are in line with the concept of sponge city. This paper analyzes the rainwater management wisdom contained in the Tongpu polder water conservancy system from the aspects of spatial pattern, water storage and discharge system and flood control ideas, and summarizes the ideas and methods worthy of reference for the construction of sponge city, which provides useful enlightenment for the follow-up development.
