关于老旧城区海绵城市系统化方案编制的探讨

Discussion on the Systematic Plan of Sponge City in Old Urban Areas

老旧城区在发展过程中面临水环境恶化、内涝频发、水生态退化、水资源短缺等一系列问题,海绵城市建设是老旧城区转变发展方式、解决涉水“城市病”的有效途径。为系统解决城市水问题,实现综合治理,保障海绵城市实施效果,有必要编制海绵城市建设系统化方案。以厦门马銮湾试点区系统化方案编制为例,从现状情况梳理、主要问题分析、问题成因定量化解析、水环境方案、水安全方案、水生态方案、水资源方案、工程综合统筹等方面对系统化方案编制要点进行探讨。

The old urban areas are confronted with numerous challenges such as water environment deterioration,frequent waterlogging,water ecological degradation and water shortage as they undergo transformations over time.To address these issues,the construction of the sponge city can serve as an effective approach to drive an environmentally friendly development mode of old urban areas,thereby offering solution for the “urban disease” associated with water.It is crucial to develop a systematic plan for the sponge city construction,which will contribute to urban water treatment,comprehensive management,and the implementation of the sponge city construction.Taking the Maluan bay pilot area in Xiamen as an example,this paper aims to explore key elements of a systematic plan,including the current situation sorting,the main problem analysis,the quantitative analysis of the major causes,the water environment improvement plan,the water safety improvement plan,the water ecology protection plan,the water resource guarantee plan,and comprehensive project coordination.
