将营养流慢下来—海口市美舍河凤翔公园生态设计
- 摘要：
- 海南省海口市是一座自然风光旖旎的南方滨海旅游城市，在近几十年来的快速城镇化进程中，人们忽视了自然河流作为城市水生态基础设施的重要性，导致城市的生态韧性和安全急剧下降。凤翔公园作为美舍河上的重要生态节点，集中暴露了美舍河流域的各种生态问题。项目设计旨在通过设计生态学途径修复场地的生态系统，系统治理内涝和水质污染问题，为周边居民营造高品质滨水慢生活环境。 借助绿色海绵技术和加强型人工湿地系统的建立，设计最终让场地中的水流及营养流慢了下来，修复了动植物栖息地，提升了生物多样性；多样化慢行系统的引入鼓励了市民及游客的绿色出行，为城市打造了一个全新的旅游、休憩、文化胜地。更为重要的是，在全球日益严峻的水污染和水资源短缺等问题下，项目所采用的设计方法在城市水质治理、防洪以及创造社会文化服务空间等方面具有重要借鉴意义。 Haikou is a coastal tourist city in Hainan Province of South China with beautiful natural landscapes. During the rapid urbanization in the past decades, the role of natural rivers as city’s water ecological infrastructure has been long-time neglected, resulting in a sharp deterioration of urban ecological resilience and security. Fengxiang Park, sitting at the middle reaches of the Meishe River, is a key ecological node in the watershed, which however had suffered from severe ecological problems. In this demonstrative project, the site was envisioned as an urban park which mitigates urban flooding and water pollution and provides citizens a quality waterfront with pleasant, slow living environment through a substantial ecosystem improvement with means of Design Ecology. Techniques of green sponge construction and the reinforced constructed wetland system deployed in the park have effectively slowed down the flow of water and nutrients, restored habitats for fauna and flora, and increased biodiversity; the introduction of a diversity of slow traffic system has brought vitality to the city by encouraging green traffic modes among citizens and tourists, creating a new tourism, recreational, and cultural destination for the city. More importantly, in view of increasingly severe issues such as water pollution and shortage around the globe, this project shows an obvious reference significance to other practices in urban water quality improvement, flooding control, and the creation of public spaces to provide social and cultural services
