广东佛山市河心岛生态修复策略与价值转化路径

Eyots Ecological Restoration and Value Transformation in Foshan City,Guangdong Province

河心岛是河流生态系统的重要组成部分,因位于水陆交错带而具有极高的生态敏感度和生态价值,但随着工业化、城镇化的快速发展,河心岛面临管控无序和生态失衡等问题。文章针对佛山市河心岛管制边界不清、修复技术难度大、利益协调复杂等难点,提出构建三阶段的河心岛生态修复总体工作框架,通过分类定位和修复时序“双评价”技术,分类确定河心岛的生态修复目标和修复等级,在此基础上提出物理综合整治、生态结构建构、堤外岸带湿地修复和堤内物种多样性提升四大生态修复策略,以及升级生态产业、发展自然教育和谋划市场交易三大生态价值转化思路,并建立工作、考评和行政三大机制,以保障生态修复工作的实施和生态价值转化的实现,为我国生态文明阶段其他城市打破经济发展与生态保护的对立局面、探索“两山”理论的实现路径提供借鉴。

Eyots are the important part of river ecosystem,which have high ecological sensitivity and ecological value.However,eyots are facing problems such as disordered control and ecological imbalance in fast industrialization and urbanization.With respect to the problems in eyots governance such as vague boundaries,technical difficulties,and complex interests,the paper firstly establishes a three-stage overall work framework,and divides eyots into three types and three levels.Secondly,based on“double evaluations”,four strategies are put forward:comprehensive physical improvement,ecological structure construction,wetland restoration in the coastal zone outside the levee,and improvement of biodiversity in the levee.Furthermore,it proposes ecological industry improvement,natural education and market transaction.Finally,relevant mechanisms of work,evaluation and administration shall be established to ensure the implementation of ecological restoration and value transformation.It provides a reference of integrating ecological development and ecological preservation,and exploring the path of the"two mountains"theory.
