区域生态可持续评价

Evaluation of regional ecological sustainability

生态可持续是区域可持续发展的基础和重要组成部分。区域生态系统由自然生态和人工生态系统构成。借鉴自然生态的V-O-R模型,建立了以基况、自然活力、自然结构、生态恢复能力和生态服务能力(CVORS)为准则的区域生态可持续评价指标体系。运用主成分分析法客观确定指标权重,对黄河三角洲区域的生态可持续进行了实证研究。

Ecological sustainable （ES） is a base and important component of regional sustainable development. Regional ecological system consists of natural and artificial ecosystems. Using V-O-R model for reference, this paper establishes evaluation index system including condition, vigor, organization, resilience and service （CVORS）. It utilizes principal component analysis method to determine index weight and chooses Yellow River Delta as a case of demonstration.
