【摘要】 生态安全是区域可持续发展的核心问题,是国家安全和社会稳定的一个重要组成部分。以徐州市为例,采用压力-状态-响应模型,选取18个评价指标,构建了生态安全评价体系;然后运用相关数学方法得到安全指数,并运用多层次分析法,确定各个指标的权重,对徐州市的各个县市进行了分区综合评价。研究表明:新沂市生态处于较安全状态,丰县生态处于危险状态,其他县市处于预警状态。更多还原

【Abstract】 The ecological security is the key problem of regional sustainable development,and the important part of the national security and social stability.Taking Xuzhou City as an example and adopting the pressure-state-response model,the authors have selected 18 appraisal targets and constructed an index system of ecological security evaluation.Then with the correlation mathematics method,the security index is obtained,and the weight of each target is determined with the Analytical Hierarchy Process.The comprehensive evaluation on each county’s security indicates that the ecological safety of Xinyi is at marginally safe level,Fengxian’s at the critical condition,others at the early warning condition.更多还原
