摘  要:
基于压力-状态-响应概念模型,从生态结构完整性出发,运用GIS和RS技术,结合生态系统服务功能价值评估与森林景观格局分析,建立包含28个指标的森林生态安全评价指标体系,以海南岛为例,运用AHP法对权重赋值,并对研究区域森林生态安全状况进行评价分析。结果表明:海南岛的中部山区市县的森林生态安全度较高,该方法进行生态安全评价科学、可行。

摘  要:
Under the conceptual fra me w ork of Pressure-state-response, in application of GIS and RS, combined with landscape pattern analysis and ecosystem service assessment, a set of 28 indicators were built to assess the forest ecological security. AHP method was utilized to weight the indicators. A case study was made in Hainan Island. The result showed that counties in the central part of the Island had relatively high value in ecological security index. It is also proved that this method is scientific and feasible.
