本文从海绵城市的发展和实践角度入手,结合前期研究与海绵城市建设相关的工程经验,对海绵城市建设的若干问题进行分析。明确海绵城市建设的主要目标和适用性;指出目前雨水系统标准体系存在的问题;强调径流污染控制在海绵城市建设中的必要性和重要性;探讨政府和社会资本合作(PPP)模式在海绵城市建设过程中的应用特点。在此基础上,从海绵城市考核要求、建设时限等方面分析了海绵城市建设的若干难点,提出海绵城市应统筹考虑“雨洪综合管理四套系统”的理念。对海绵城市建设相关问题和建设难点的解析将有助于现阶段和未来海绵城市的建设和发展,也为海绵城市建设的有序推进提供导向性参考。
In this paper, starting from the perspective of sponge city development and practice, combining with the previous research on the sponge city construction-related engineering experience, this paper analyzes some problems of sponge city construction. Clarify the main objectives and applicability of sponge city construction; point out the problems existing in the current rainwater system standard system; emphasize the necessity and importance of runoff pollution control in the construction of sponge city; explore the mode of government and social capital cooperation (PPP) Application characteristics in the process of construction. On this basis, the paper analyzes some difficulties in the sponge city construction from the sponge city assessment requirements and construction time limit, and puts forward that the sponge city should take “the four systems of integrated management of rain and flood” into consideration. The analysis of problems related to sponge city construction and construction difficulties will be helpful for the construction and development of the sponge city at the present stage and in the future, and also provide a guideline for the orderly progress of sponge city construction.
