高度城市化背景下围填海区域生态修复的探索与实践——以厦门市筼筜湖综合治理为例

Exploration and Practice of Ecological Restoration of Sea Reclamation Areas,Under the Background of Highly Urbanized:Integrated treatment of Yundang Lagoon in Xiamen

随着我国沿海地区城市化和社会经济的不断发展,围填海已成为沿海地区解决用地紧张和城市扩张的普遍途径,但也引发了一系列生态和民生问题。厦门市早年在围填筼筜港的开发建设过程中,面临了严峻的环境变迁和生态破坏,为此,厦门市开展了数十年卓有成效的筼筜湖综合治理和围填区域新城区的规划建设与生态环境保护工作,通过制定法规和城市发展规划、截流污水、底泥清淤、引潮活水、种植红树林、建造生态岛等措施,显著改善围填海区域的生态环境,有效促进了城市发展、升级和转型,推动了厦门市生态保护与经济建设并重高质量发展模式的形成,社会效益、生态效益和经济效益显著。

With the continuous development of coastal urbanization and socio-economy,sea reclamation has become a common way to solve land shortage and urban expansion in China,but it has also triggered a series of ecological and livelihood issues.In the early years,Xiamen faced severe environmental change and ecological damage during the process of reclamation and development of Yundang harbor.In order to improve the environmental quality,Xiamen has carried out decades of effective integrated treatment for the Yundang Lagoon.At the same time,Xiamen has planned and constructed a new urban area in an orderly manner in the reclamation area of the Yundang Lagoon.By the measures such as formulating legal systems and urban development plans,interception of sewage,sediment dredged,bringe in the tide to rejuvenate the lagoon,planted mangrove,builded an ecological island,the ecological environment of the sea reclamation areas has been significantly improved.These measures have significantly improved the ecological environment of the reclamation area,effectively promoted the development,upgrading and transformation of the city,and promoted the formation of a high-quality development model that attaches equal importance to ecological protection and economic construction in Xiamen,with significant social,ecological and economic benefits.
