山西省生态系统安全评价研究

基于P-S-R(压力-状态-响应)模型,从经济、民生、资源及环境保护角度,构建了评价山西省生态系统安全指标体系,同时将突变级数法与因子分析法相结合,构建评价区域突变模型,对2004—2013年山西省生态系统安全进行综合评价。结果表明：2004-2007年,山西省生态系统安全隶属度呈上升趋势,在2008-2009年则出现快速下降,在2009年有明显突变,这反映山西省的经济、民生、资源与环境四者之间还未能协调发展。

The Ecosystem Security Assessment of Shanxi Province

Based on P-S-R (pressure state response) model, the security index system of ecological system in Shanxi province was constructed from the perspective of economy, people's livelihood, resources and environmental protection, At the same time, the catastrophe progression method and factor analysis method were combined to construct the model of the evaluation of the evaluation area. The results showed that: In 2004-2007, the degree of membership of the ecological system in Shanxi province is increasing, and the level in the 2008-2009 is rapidly declining, the security level of its ecological system has a significant change in 2009, which reflects the economic, livelihood, resources and environment of the four provinces has not been coordinated development.
