基于生态功能保护的苏州城市绿道规划设计

Analysis of Greenway Planning on the Principle of Ecological Protection:A Case Study of Suzhou

城市具有独特的地域特征和生态环境的敏感性,但是随着城市建设快速发展,城市生境破碎、生态功能脆弱问题日益严重。绿道是城市生态保护的重要手段,研究基于生态保护原理的绿道规划方法具有现实意义。以苏州为例,结合城市生态结构特征,以生态保护理论为指导,分别从构建以生态维育为目标的生态安全格局规划,倡导以生态功能为导向的绿色廊道体系设计,强调以生态服务为提升的慢行系统设计等不同层面规划绿道网络体系,构建城市生态安全格局。

There are unique local characteristics and the sensitivity of the ecological environment in the city. But with the rapid development of urban construction, the problems of urban habitat broken and the fragile ecological function are increasingly serious. The greenway is an important means of the urban ecological protection. Studying the greenway planning method based on urban ecological protection has practical significance. In this paper, using Suzhou as a case study, combining with the feature of urban ecological structure, and guiding by the theory of ecological protection, the greenway planning strategy is explored on different levels, such as constructing the planning of ecological security pattern based on the goal of the ecological sustainable development, advocating the green corridor system design oriented on the ecological function, and emphasizing on ecosystem services in order to promote the slow traffic system design, and building the urban ecological security pattern.
