摘要
我国城市社区建设核心已逐步从城镇扩张“摊大饼”转向旧社区改造“有机更新”以及构建生态宜居的城市系统。针对高密度城市老旧社区水景普遍存在的维护成本高、效果不佳、居民满意度低等问题,本文通过研究水弹性系统,进行老旧社区弹性模块化水景的构建与实践,从而提升水景的维护效率,修复社区生态。弹性模块化水景有三大优势,即富于变化与统一、网络化管理模式以及疫情期间的水安全保障。通过梳理老旧社区的水系统及其存在的问题,提出适合老旧社区水景的管理模式并构建适宜的水景模块。本文以上海市杨浦区文化花园老旧社区为案例,分析并选择了适宜小区的三大模块,即活水科普模块、雨水调蓄模块、循环水景模块,并将其进行组合和连接,构建了高适应性和可持续的社区水景。同时,构建了新的城市弹性水管理系统模式,将弹性模块化水景应用于高密度城市社区水景改造,社区水景作为模块化基础设施,将雨水、河流、绿带、社区等融入绿色网络,构筑自然、高效、弹性、具有自修复功能的动态绿色水管理系统,修复城市过度干扰的生态环境,促进城市与自然协调,形成人与自然共生的城市模型。
Nowadays,China’s developing urban period has gradually shifted from urban expansion to existing community renewals in city centers.Through two decades of continuous efforts,the government advocates ecological and sustainable urban systems to make cities more livable and friendly to citizens.The Chinese People’s Political Consultative Conference recently proposes the formulation of The 14th Five-Year Plan(2021-2025)for National Economic and Social Development and the Long-Range Objectives Through the Year 2035.Objectives include building an ecological and civilized city,promoting urban ecological restoration,strengthening old residents reconstruction and new urban community construction,enhancing urban flood control and drainage capacity,as well as building sponge resilient cities.As one of the frequently used elements in community landscapes,waterscape should have significant values in terms of aesthetics,ecology,entertainment,and culture.However,due to urgent issues like higher maintenance costs,poor performance,loss of functions,and residential dissatisfaction with water features in high-density urban communities,community waterscapes’renewal currently becomes a general concern.It needs to be solved with a high priority.In another point,researches bring about a challenge on achieving the balance of aesthetics,ecology,and function of waterscape.As the city’s framework,residential areas need both improvements in living environments and systematic management.The paper discusses theories related to the resilient city and main approaches,and significant roles of resilient water systems in urban stormwater management and ecological restoration.After the research analysis,the paper finally focuses on applying modular waterscapes.In community developments and renewals,modular waterscapes have three main advantages:the richness of changes and unities,network management,and water safety guarantees during the epidemic,which are of great benefits to the sustainable use of community waterscape.However,approaches of
