海绵城市功能分区方法的研究

Study on the zoning method and related indexes of the sponge City

近年来,"海绵城市"规划与建设成为学术界研究的热点,海绵城市目标制定及其分解落实海绵城市规划的核心,海绵城市建设分区是有效引导海绵城市建设目标分解落实的重要环节。本文以某城市海绵城市规划为例,阐述该地区海绵城市规划控制指标体系构建的方法,并通过合理分析确定了规划区的核心指标——年径流总量控制率,并对年径流总量控制率目标进行分区分解,提出相应的海绵城市建设管控要求。

In recent years,Sponge City planning and construction has become a hot-spot of academic research.The core of Sponge City planning is to formulate and decompose Sponge City goals.Sponge city construction zoning is an important link to effectively guide the decomposition and implementation construction goals of Sponge City.The paper elaborated the method of the formulation of control index system by taking a Sponge City planning as an example.The core index-annual total runoff control rate were determined by reasonable analysis.The target of annual total runoff control rate is decomposed according to the zoning,and this paper put forward the corresponding control requirements of sponge city construction.
