海绵城市理念在某老旧小区综合改造中的应用
- Title:
- Application of Sponge City Concept in Comprehensive Reconstruction of an Old Residential Community
- 摘要:
- 为更好地提升居民的生活品质，实现生态文明建设，苏州某老旧小区改造将海绵城市建设、绿色人居环境理念纳入其中，以问题为导向，考虑人居需求及城市规划发展，遵循以人为本的“绿色、健康、邻里、舒适”目标原则，对小区建筑、道路、排水、景观等进行综合改造。在采用立面出新、排水系统改造、道路改建等老旧小区传统改造基础上，排水系统重点综合源头削减、过程控制、末端治理的技术思路；通过系统化梳理现状，在室外雨污分流改造完成的基础上，采用建筑雨落管断接、支管截流、干式植草沟、沿河生物滞留带、停车场生态化改造等系统化技术手段，可将年径流总量控制率、面源污染削减率由18.5%、15.7%分别提高至50.2%和42.7%。该小区的改造结合景观提升，优化居住区环境，提升居民幸福感指数，可为其他老旧小区改造提供参考与借鉴。
- Abstract:
- In order to better improve the living quality of residents and realize the construction of ecological civilization, the concept of sponge city construction and green living environment are introduced into the old community reconstruction project in Suzhou. Based on problem-orientated, considering the needs of human settlements and urban planning development, in accordance with the people-oriented principle of “green, healthy, neighborhood, and comfort”, comprehensive transforming of the residential building, roads, drainage, landscape was carried out. On the basis of the traditional transformation of old community such as facade innovation, drainage system transformation, road reconstruction and so on, the technical ideas of comprehensive source reduction, process control and end treatment of the drainage system are emphasized. By systematically combing the present situation and on the basis of outdoor rain and sewage separate transformation, the total runoff control rate and non-point source pollution reduction rate can be increased from 18.5%，15.7% to 50.2% and 42.7%, respectively, by using systematic technical means, such as building rain pipe disconnection, branch pipe interception, dry grass planting ditch, biological detention zone along the river, ecological transformation of parking lot and so on. Combining the landscape improvement, the project optimized the living environment and improved the residents’ happiness index, which could provide reference for the other old communities’ renovation.
