基于海绵城市理论的下沉式绿地选址及设计要点研究

Research on Site Selection and Design Points of Sunken Green Space Based on Sponge City Theory

下沉式绿地是海绵城市理论下解决城市水问题的一个有效途径,但个别城市盲目推行下沉式绿地带来了新一轮的生态破坏。通过文献研究和实践总结,探讨了下沉式绿地的概念、功能等,提出了城市下沉式绿地的相地原则及要求,为科学建设具有城市雨洪系统的调控功能、城市水资源的收集利用功能的海绵城市提供了有力的理论基础。

Sunken green space is an effective way to solve urban water problems under the theory of sponge city. However,blindly promoting the sunken green space in some cities has brought about a serious of environment damage.We reviewed the current concept and functions of the sunken green space.Moreover, principles and requirements of the sunken green space construction were also proposed based on the literature and practice.The present study provided a strong theoretical basis for the scientific construction of sponge city, which had the multi-functions of regulating and controlling urban rainwater, collecting and utilizing urban water resources.
