中部地区生态与经济的系统耦合比较与评价

Comparison and Evaluation on System Coupling of Ecology and Economy in Central Region

中部地区各省经济的迅速发展对生态环境保护提出了严峻的考验。基于"压力——承载——反馈"模型,运用主成分分析法分别对中部地区六省的生态与经济系统耦合度进行测算,研究发现:中部地区生态与经济系统逐渐进入"良性耦合"阶段;经济系统对生态系统的反馈较为积极;生态系统的承载压力逐渐增强。

The protection of ecology environment meets the severe challenges because of rapid development in central region. Based on ＂Pressure - Carrying - Feedback＂ model, this paper measures the coupling degree of ecology and economy system in central region by using the principle component analysis method. The results show that the ecology and economy system coupling is going into smooth phase; the feedback of economy system is positive and the pressure on ecology system is strengthening.
