生态文明理论指导下的公园生态景观设计实践——以成都大源中央公园为例

Park Ecological Landscape Design Practice under the Guidance of the Ecological Civilization Theory——Case Study of Dayuan Central Park in Chengdu

成都市天府新区的大源公园原址为20世纪80——90年代的郊区垃圾填埋场,根据城市向南扩张发展的需求,规划为城市新城居住区组团的核心开放空间。基地原有的废弃物已分解碳化并自然压实。通过整体评估,实施了大区域水系统整合改造,组织中水回用,建立循环及建造湿地提升水质;配合竖向设计进行种植土改造,以本土树种为主,四季变化层次丰富的乔灌木布置等方式,成功将基地改造为生态基底良好、自然资源丰富的城市中心公园。公园与成都市的绿地系统和慢行网络衔接,方便到达;广场、草坪、水岸、花园等多样空间为人们提供了休闲活动的场所;社区商业及小规模的餐饮设施完善了配套服务。于2013年重新开放后,成为区域居民及城市新城的生活舞台。建成后的大源公园,扭转了旧有残破废弃的郊区形象,成为城市建设发展与其他项目投资的催化剂,为成都市向南的发展策略落实起到了积极的示范作用。

Dayuan Park, located in the Chinese city of Chengdu＇s Tianf^a New District, was completed in 2013. The site, originally a landfill during the 1980s and 1990s, is now an important open space for the city＇s southern residential clusters. The redevelopment not only transformed the site＇s sleepy suburban image, but it also became a catalyst for urban development and investment and a demonstration area for Chengdu＇s strategic expansion southwards. Over the course of twenty years, waste disposed on site had decomposed and compacted naturally creating a unique challenge, which was responded to with an integrated proposal grounded in resilient ecological design. Key water management strategies included water recycling, establishing a closed water cycle and introducing wetlands to improve water quality. Soil remediation was done in conjunction with existing and proposed grading, while native species were used to create a vibrant multi- layered plant palette with rich seasonal changes. The result is all urban park with a restored ecological environment and thriving natural resources. The park forms part of the city＇s wider open space network, with ample access via non-vehicular transportation modes. The design takes into account adjacent land use, providing ample recreational opportunities for the community with facilities like plazas, lawns, waterfront access, promenades, and retail and F＆B outlets. Since completion, Dayuan Park has been drawing users from its neighbouring residential districts, setting the stage for vibrant living in Chengdu.
