| 摘 要： | 为研究海水养殖业对海岛生态系统脆弱性的影响,通过分析海岛生态系统本身所具有的脆弱性,探讨了海水养殖活动对海岛生态系统脆弱性的影响机制。根据海岛生态系统的特点,将海岛生态系统划分为岛陆子系统、潮间带子系统和近海子系统;采用指标评价法构建VDS(暴露—敏感—适应)框架,初步探索了海水养殖业对海岛生态系统脆弱性影响的评估指标体系和评价方法。本研究结果可为今后海水养殖影响下的海岛生态系统脆弱性评估工作提供思路。

| Abstract: | The vulnerability of an island ecosystem is evaluated and mechanism of the effect of mariculture on the vulnerability of the island ecosystem is discussed in order to investigate the impact of human activities including mariculture on the vulnerability of island ecological system. An island ecosystem is divided into the island land sub-system, intertidal subsystem and offshore subsystem based on the characteristics of the ecological system formed by the combination of land and sea. The vulnerability of island ecosystem, and the potential factors leading to the fur-ther development of island vulnerability are discussed. The evaluation index system and assessment of vulnerability in mariculture island are preliminarily explored using index evaluation method and establishment of the exposure-sensitivity-adaptation model to provide some ideas for assessment of the vulnerability of the island caused by the mariculture impact in the future. |
