基于保护对象的海岛特别保护区范围划定技术

Delimiting the Range of the Special Conservation Area of Islands in the Sea Based on the Protecting Object

海岛生态系统独特且脆弱.建设海岛特别保护区对于减缓海岛生态环境恶化、防止生态系统退化和海岛侵蚀具有重要的意义和作用.目前,尚未有海岛特别保护区范围划定的方法和标准,制约了海岛保护和资源合理利用.本文针对不同保护目标和属性的海岛特别保护区,依据其保护对象、管理水平和外在风险,开展保护区范围划定的案例研究,据此提出了单一保护对象和多目标保护对象海岛特别保护区范围的划定依据和方法,为海岛特别保护区范围的划定提供理论和实践探索.

The ecosystem of island in the sea is unique but extremely frail. Building special conservation area for islands in the sea has vital significance to retarding the worsening ecological environment, preventing ecosystem degradation and island erosion. However, at present, there is still no method and standard for delimiting the scope of special conservation area of islands in the sea, which restricts the island protection and reasonable use of resources. This paper is about the case studies of delimiting the scope of different special conservation areas with different protecting aims and properties, according to the protecting aim, management level, and external risk. According to the study, this paper puts forward the sole protection object method and multi - objective protection object method for delimiting the scope of special conservation area of islands in the sea. This study provides theoretical and practical exploration for delimiting the scope of special conservation area of islands in the sea.
