摘 要:大都市圈郊区日渐成为大型居住社区的首选,都市圈郊区既有河道存在河道淤积、护岸塌陷、污染严重等问题,严重影响大型居住社区的人居环境。本研究针对大型居住社区多元城市生活空间的需求,提出了河道生态治理的设计原则,并结合嘉定区城北大居河道综合整治工程,从水系沟通、护岸设计、亲水平台等方面阐释了大都市圈郊区现代化大型居住社区河道生态治理设计,可为类似工程提供借鉴。

Abstract: The suburbs of metropolitan area are becoming the first choice of large residential communities. The existing rivers in the suburbs of metropolitan area have problems such as river siltation, bank protection collapse and serious pollution, which seriously affect the living environment of large residential communities. Facing the needs of multiple urban living spaces in large residential communities, this study proposed the design principles of river ecological governance, and combined with the comprehensive river regulation project of Chengbei Daju in Jiading District, explained the river ecological governance design of modern large residential communities in the suburbs of metropolitan area from the aspects of water system communication, revetment design, hydrophilic platform, etc., which can provide reference for similar projects.

隨着长三角一体化战略的深入实施,核心城市聚集效应使得大都市圈形成。以上海为代表的超大城市人口规模不断增加,由于城市核心区土地资源的稀缺性,上海市五大新城战略的实施使得大型居住区的规划越来越多分布到都市圈郊区。在都市圈郊区建设大型居住社区,对河道生态整治提出了更高的要求,以实现“安全、资源、环境、景观”的功能。
都市圈郊区河道现状多为原始乡村河道,建筑生活垃圾随意投入,边坡塌陷严重,造成河道普遍淤积;部分河道为断头河,河道现有过水断面较小,河道周边环境杂乱,河道坡面亟需清理;河道周边水体长期遭受严重污染,超过了河道的水环境承载力,直接影响居民的生活环境和投资环境;河道景观和亲水设施缺乏,人居体验不佳;同时由于通勤需求,都市圈郊区的大型居住社区周围设置轨道交通站点,与河道水系沟通相互影响。……
