城市生物多样性恢复途径与实例研究

Approaches and Case Study of Urban Biodiversity Restoration

城市生物多样性是城市生存与发展的基础,是实现城市生态系统可持续性的保证。本文以相关生态学理论为指导,针对广州市海珠生态城的生态恢复实际,并结合海珠生态城"以万亩果林湿地为核心,打造具有岭南水乡魅力的花城、水城、绿城特色生态城市样板区"的总体定位,提出了该区域的生物多样性恢复目标和规划思路,并重点围绕湿地生境分区、栖息地修复、水环境改善、恢复物种筛选、区域生物多样性构建等方面进行了探讨,建立了海珠生态城湿地生物多样性恢复规划策略。

Biodiversity is the foundation of the survival and development of cities. It is also the guarantee for the sustainable development of urban eco-system. Based on ecology theory and a case study of eco-restoration of Haizhu Eco-town in Guangzhou, it illustrated how a distinctive eco model area with the charm of Lingnan Region of Rivers and Lakes was created and how a flower city, water city and green city was built with Wan-mu Orchard wetland as the core of biodiversity restoration. It proposed the eco-biodiversity restoration goals and objectives for Haizhu District and elaborated on wetland habitat partition, habitat restoration, water environment improvement, species selection of restoration, and regional biodiversity construction. It also put forward the planning strategies for the biodiversity restoration of the wetlands of Eco-town in Haizhu.
