生态系统服务导向的城市废弃地修复设计--以天津桥园为例

Ecosystem Services Oriented Regenerative Design of Deserted Urban Land:Tianjin Qiaoyuan Project

本文提出改变通常城市公园的建设理念和方法,以全面改善生态系统服务为目的,进行城市绿地建设和城市废弃地的生态恢复。案例是一个22hm2的公园,原来是一个废弃的打靶场,垃圾遍地,污水横流,路人掩鼻,临建破败,不堪入目,土壤盐碱。景观设计师应用生态恢复和再生的理论和方法,通过地形设计,创造出深浅不一的坑塘,有水有旱,开启自然植被的自我恢复过程,形成与不同水位和盐碱度条件相适应的植物群落。将地域景观特色和乡土植被引入城市,形成独具特色的城市生态基础设施,为城市提供了多种生态服务,包括雨洪利用、乡土物种的保护、科普教育、审美和游憩。

This paper proposed that the improvement of ecosystemsi^- services are the goals of urban green design and construction. This is a park of twen ty-twohectares in The Hedong District of Tianjin. Through Regenerative Design and by changing landforms, the natural process of plant adaptation and community evolution is introduced to transform a former deserted shooting range used as a garbage dump, into a low maintenance urban park; providing diverse nature＇s services for the city including containing and purifying storm water; improving the saline-alkali soil, providing opportunities for environmental education and creating a cherished aesthetic experience.
