基于PSR模型的生态保育海岛评估框架研究—以大连西蚂蚁岛为例

国家非常重视海岛保护工作，对被破坏的海岛进行生态修复对于维护生态安全、改善岛民生活环境、促进海岛可持续发展具有非常重要的意义。我国海岛生态修复的研究相对滞后，特别是有关海岛整治修复前评估方法的研究较少。本文在梳理海岛生态修复发展现状和PSR模型在生态评价领域应用现状的基础上，从海岛生态胁迫、海岛周边海域健康状态和海岛资源环境管理机制三个层面介入，提出生态保育海岛评估指标体系，旨在为此类海岛生态整治修复与管理的目标制定提供理论借鉴。

Research on island assessment framework of ecological conservation based on PSR model-taking the West Ant island of Dalian as an example

The state attaches great importance to the protection of the island, and the ecological restoration of the damaged island is of great significance to the maintenance of ecological security, the improvement of the living environment of the islanders and the sustainable development of the island. The research on island ecological restoration in China is lagging behind, especially in the study of Island reclamation before restoration. On the basis of combing the development status of island ecological restoration and the application of PSR model in the field of ecological evaluation, this paper puts forward the index system of ecological conservation Island assessment from the three levels of island ecological stress, the health state of sea island surrounding sea island and the management mechanism of island resource and environment, aiming at the ecological renovation of this kind of island. It provides a theoretical reference for the goal making of complex and management.
