生态设计理论的本土化表达--以"温榆河生态走廊规划(朝阳段)"为案例

我国在发展过程中面临着严重的生态危机,但由于缺乏现实的实施手段和管理体制,生态理念还很难真正落实.基于此,本文引入了生态设计的理念,以"温榆河绿色生态走廊规划(朝阳段)"为案例,来探讨生态设计理念如何在规划设计中进行本土化表达,以期探索一种能结合本土实际的生态化发展模式.     

温榆河生态走廊

温榆河生态走廊的建设，为北京城市近郊区域的可持续发展注入了新的活力。 发展与生态是当前北京城市建设的两大突出主题，东部是未来北京城市空间与产业发展的主要方向，而温榆河生态走廊将会成为东部发展带上的一块生态绿洲，兼具发展与生态的双重功能。EDSA认为：作为未来的世界城市，生态与全球环境的概念应当在北京的区域规划中加以强调，此项目也是主规划师陈跃中大景观理念的一个实践，旨在规划未来新城的发展，达成河域的自然环境与城市发展之间的平衡。[编者按]

基于生态廊道原理的城市河流景观空间分析

当今城市河流面临生态环境恶化、干扰影响加剧、河流景观匀质化等情况,呈不可持续发展的态势.国内外众多学者对城市河流景观的生态廊道功能和结构的研究已取得一定进展,而对于廊道的三维空间特征综合性研究还未涉及.笔者尝试运用景观生态学理论对河岸景观廊道二维断面空间表征进行模式化归纳,并提出不同模式下的河岸线状绿地匀质空间的优化设计策略,策略考虑了模式的空间、时间特征以及实践指导性;同时,在廊道纵深方向,利用廊道网络特征指数,进行河岸线状绿地匀质空间的网络空间结构定量分析;实现了城市河流景观的生态廊道三维特征辨识与优化,也为多尺度综合研究城市河流景观生态功能提供新视角、新途径.

山城生态环境保护策略初探

城镇生态环境保护,对城市持续发展,加速开发与建设具有重要战略意义.城镇位于自然环境之中,保护城镇生态环境,首先要保护城镇的区域生态环境.合理开发与利用生物资源,保持自然生态维持在一个良性循环中,建立生态经济协调发展战略,使从单纯的经济发展转向经济社会发展和生态环境建设结合的同步发展,开发应用生态技术保持区域生态环境.然后加强城镇的生态环境保护.科学规划、合理布局工业、发展生态工艺,保护环境;加强全城镇绿化系统规划与建设等措施保护城镇生态环境.只有把保护城镇区域生态环境同保护城镇生态环境结合起来,统一规划,才能达到城镇生态环境保护的目的.

Ecological Design Across Interface: Ecosystem Restoration of Pengxi River/Reservoir in Three Gorges Reservoir Area,Chongqing

Riparian zone is a typical ecotone that connects terrestrial and aquatic ecosystems. At the same time, environmental stress magnifies here and the natural regulation of rivers is extremely active. In other words, the most dynamic and vibrant interactions between rivers and landscapes occur in riparian zones. However, the construction of dams and the operation of reservoirs have turned many riparian zones into river/reservoir alternation interfaces, influenced the shaping of hydrological and water environment, and the basin ecosystem as well. By introducing the definition and ecological characteristics of river/reservoir interface, this paper proposes the strategies and technical framework for the ecological design of river/reservoir interface. By studying the ecosystem restoration project of river/reservoir interface of Pengxi River in Three Gorges Reservoir Area of Chongqing, which emphasizes the comprehensive element design, structural design, functional design, and process design, this paper aims to provide a reference for related research and practice on river ecosystem restoration. The results of ecological performance analysis showed that the restored ecosystem of the Wuyangba river/reservoir interface has an obvious increase in habitat type diversity and biodiversity, a strong ability of plant communities to adapt to seasonal water level fluctuation, and an improvement in purifying non-point source pollution. The project demonstrates the coordination and symbiosis of interface ecological restoration and waterfront landscape construction and optimization. The project offers an innovative effort in exploring ecosystem restoration design and practice of river/reservoir interfaces. The design strategies and framework can be a reference for other ecosystem restoration cases that are affected by water level fluctuation in river/reservoir interfaces.

SHANGHAI SANLIN VALLEY PARK — LANDSCAPE DESIGN OF AN URBAN GREEN WEDGE

As one of the eight major green wedges within Shanghai’s overall urban planning in the city center, Sanlin Valley Park serves as an important intersection between ecological corridors along the Huangpu River and Shanghai’s outer ring road. During the rapid urbanization process, the city’s ecology has been facing constant deterioration. Furthermore, the city is experiencing an alarming loss of biodiversity, as well as increasingly severe urban heat island effect. To alleviate these issues, the project adopts a “valley” concept as the core of its design and utilizes thoughtful design strategies in five aspects: water management, wind corridors and micro-climates, ecosystem, transportation, and program and experience. With these strategies, the design team aims to improve the site’s connectivity, restore its ecology, reshape habitats, create a resilient landscape, and forge a vibrant urban hub that can also serve as the city’s ecological research base. During the design process, the design team adopts certain principles of landscape practices within the USA — that a project should encourage public participation of all socio-economic levels and place emphasis on the experience and benefits of the public. This form of multi-lateral cooperation allows for the park to constantly have its design plan reviewed and improved. It also allows for iterative responses to issues on the ground during construction. Last but not least, it instigates careful considerations of how to manage the park and its ecosystem, both in terms of cost and feasibility. By adopting all of these principles, the design team aspires to truly accede to citizens’ needs, all while introducing a sustainable ecosystem that would, ultimately, contribute to a much improved ecology and economy.
