城市雨水景观设施的建设与改造

The Construction and Renovation of Urban Rainwater Landscape Facilities

从水资源的匮乏和恶化出发,分析雨水回收利用的必要性和可行性;提出了以原有的自然水脉为网络进行城市规划以及建设和改造城市雨水景观的理念;利用城市原有的水系进行雨水和生活用水的收集,通过街道绿地中的水道,借助地势,将城市各区域的水汇集到城市低处的公园内进行统一的净化、协调,使城市雨水得以高效率的回收;并以山东即墨新城规划为例,从城市绿地系统规划的角度出发,以居住区、街道、公园等典型区域为例,为整个城市的水回收净化的景观设施设计提供了建议。

According to the shortage and deterioration of water resources, the necessity and feasibility of rainwater collection are analyzed in this paper. The idea of conduct the city planning with the original natural water systems as the nelwork and constructing and renovating the urban rainwater landscape is proposed. The original water systems of the city are used to collect the rainwater and domestic water, and the water collected from various areas comes together to the park of lower position through the water channels in the urban green space system and the terrain. The urban rainwater are high-efficiently recycled and centralized purification and coordination in the park. With the planning of Jimo City, Shandong Province, as the example, from the viewpoint of urban green space planning and with the analysis of its lypical sectors such as residential areas, streets and parks, proposals on the design of landscape farcicalities for water recycling and purification of the whole ally are given.
