中文摘要:
      海岛生态系统是海洋生态系统的重要组成部分。近年来,随着海岛人为活动数量不断增加,加速了对海岛生态环境的破坏,一些海岛生态失衡严重,生态系统受损加剧。而对受损海岛生态系统开展人工参与下的主动式生态恢复,是目前较为主流的恢复方法和手段,菩提岛整治修复项目正是基于上述修复理念开展并完成的。本文以菩提岛海岛及周边海域为研究区域,基于 PSR 模型,以 RS 方式为主要指标获取方式,构建了适用于我国海岛整治修复模式下的海岛生态系统健康评价体系,对其整治修复前后生态系统健康状况开展评价分析。结果显示:2008 年,该岛生态系统健康值 IEI 为 0.374 0,生态系统较脆弱,整体状况较差,亟须开展保护与修复工作;2014 年,经岛体修复并趋于稳定状态后,该岛生态系统健康值 IEI 提升至 0.673 8,生态系统较健康,处于稳定状态,但仍具有上升空间。经整治修复前后纵向对比,生态系统健康波动值 驻IEI 为0.299 8,表明该岛生态系统经过修复后已有所好转。
英文摘要:
      Islands ecosystem is an important part of marine ecosystem. In recent years, with the increase of human activities on islands, the destruction of islands' ecological environment has been accelerated. Some islands are facing serious ecological imbalance and their ecosystem has been damaged seriously. The active ecological restoration with artificial participation of the damaged island ecosystem is currently mainstream recovery methods and means. The Puti Island Restoration Project is based on the above-mentioned restoration concept. Based on the RS model, using the remote sensing method as the main indicator acquisition, this paper selected the completed Puti Island as research object to construct an island ecosystem health assessment system which is suitable for China's island restoration method. The island ecosystem health status before and after restoration was evaluated.. The result shows that in 2008, the island's ecosystem health value IEI was 0.374, the ecosystem was weak and the overall situation was poor. So it is urgent to carry out protection and restoration work. However in 2014, after the island was repaired and stabilized, the island ecosystem health value IEI has been raised to 0.673 8. The ecosystem is healthy and stable, and still has room for improvement. After vertical comparison, the ecosystem health fluctuation value IEI was 0.299 8, suggesting improvement after the restoration of the island ecosystem.
