摘要
随着经济的快速发展和工业化进程的加快,环境污染与生态破坏日益严重,生态环境问题已逐步上升到生态安全问题。如何通过定量分析表征生态安全的状态、程度和水平成为人们越来越关注的问题。文章简述了层次分析法(AHP),并应用此方法,对所构建的4层区域生态安全层次结构模型中各指标的重要性系数进行了定量确定,通过计算,最终得到切实的指标权系数结果,从而为随后的区域生态安全综合评价奠定了可靠数据基础,也为生态安全管理提供了科学的依据和指导。
With the rapid development of the economy,ecological security is becoming more necessary,and how to express the status and degree of ecological security quantitatively is an important issue. In this paper,the Analytical Hierarchy Process(AHP) method is applied to determine the weighting coefficients of the indexes in the evaluation system of regional ecological security. A four-layered hierarchical structure model of regional ecological security is presented,and practical results are obtained. The results provide a reliable and scientific data basis for subsequent comprehensive appraisal and regional ecological management.
