The evaluation on island ecological vulnerability (IEV) can help reveal the comprehensive characteristics of the island ecosystem and provide reference for controlling human activities on islands. An IEV evaluation model which reflects the land-sea dual features, natural and anthropogenic attributes, and spatial heterogeneity of the island ecosystem was established, and the southern islands of Miaodao Archipelago in North China were taken as the study area. The IEV, its spatial heterogeneity, and its sensitivities to the evaluation elements were analyzed. Results indicated that the IEV was in status of mild vulnerability in the archipelago scale, and population pressure, ecosystem productivity, environmental quality, landscape pattern, and economic development were the sensitive elements. The IEV showed significant spatial heterogeneities both in land and surrounding waters sub-ecosystems. Construction scale control, optimization of development allocation, improvement of exploitation methods, and reasonable ecological construction are important measures to control the IEV.
海岛生态脆弱性评价可以揭示海岛生态系统的综合特征，为控制海岛人类活动提供参考。本研究建立了一个反映海岛生态系统陆海双重特征、自然和人为属性以及空间异质性的海岛生态脆弱性评价模型，并以中国北方庙岛群岛的南部岛屿为研究区域。分析了海岛生态脆弱性及其空间异质性，以及对评价要素的敏感性。结果表明，该群岛的海岛生态脆弱性处于轻度脆弱状态，人口压力、生态系统生产力、环境质量、景观格局和经济发展是敏感要素。海岛生态脆弱性在陆域和周边海域子生态系统中均表现出显著的空间异质性。控制建设规模、优化开发布局、改进开发方式和合理进行生态建设是控制海岛生态脆弱性的重要措施。
