摘要
生态安全是可持续发展研究的一个新领域,文章从复合生态系统的内涵出发,以压力(Pressure)—状态(State)—响应(Response)模型(简称PSR)为概念框架,结合层次分析等数学工具,构建以区域为空间尺度的森林生态安全评价指标体系,提出森林安全度模型(FESI),并对海南省森林生态安全进行定量动态评价。结果表明该方法框架完整、逻辑严密、层次清晰并有很强的操作性;评价结果显示2003～2008年的海南的森林生态安全度总体呈上升趋势。
Ecological Security is a frontier area for sustainability research.In this paper,A set of criteria and indicators for assessing forest ecological security on region-scale was developed based on Pressure-State-Response（PSR） framework and Analytic Hierarchy Process,Forest Ecological Security Index（FESI） was proposed.Based on the CI developed,a dynamic assessment was conducted in Hainan,China.The results prove that PSR framework captures causal linkages within the ecological system,helps to develop indicators in a logical and systematic manner,and it is applicable.The result shows that the FESI of Hainan was improved during 2003-2008.
