摘要
本研究比较了生态安全与其他相关概念(生态风险、生态系统健康、生态系统服务功能和生态承载力)之间的关系,对生态安全理论框架(PSR、PISR、DPSIR、DSR和DPSER)和评价方法(熵权法、主成分分析法、层次分析法、灰色关联分析法、模糊综合评价法、人工神经网络、物元分析法、生态足迹、景观生态安全模型、数字生态安全模型)进行的总结,分析比较了各方法的优缺点,并展望了区域生态安全评价方法的发展方向。
This paper introduces and compares the concepts of ecological security and other related concepts( including ecological risk,ecosystem health,ecosystem servers and ecological capacity),sums up the review to assess regional ecological security theory frames( including PSR,PSIR,DSR,DPSIR and DPSER) and evaluation methods( including entropy method,principal component analysis,analytic hierarchy process,grey correlation method,fuzzy comprehensive evaluation method,artificial neural networks,matter-element analysis,ecological footprint,landscape ecological security pattern method and digital ecological security model),compares the advantages and disadvantages of various methods,and discusses regional ecological security evaluation method development direction.
