摘要: 本文探讨了区域生态安全评价指标的选取和赋权方法,建立了区域生态安全的主成分投影评价模型,并通过安徽省17个地级市的实证分析,得出具有较强实际意义的结论,为区域生态安全评价研究和生态安全管理实践提供理论基础。

关键词: 区域生态安全, 评价指标, 主成分投影, 熵权法

Abstract: This paper studies the selection of index system for evaluation of regional ecological security and weighting method,establishes the model of the principal component projection to assess regional ecological security.Through the empirical analysis of seventeen regions in Anhui province,the paper proves that the method is reasonable which can be used as theoretic basis for studies on evaluation of regional ecological security and management of eco-environment.

Key words: regional ecological security, evaluation index, principal component projection, entropy method
