黄河三角洲高效生态经济区人口、经济与环境协调发展研究——基于主成分与耦合协调度模型

Study on the coordinated development of population-economy and cology coupling of the efficient ecological economic zone of the Yellow River delta based on principal component analysis and coupling coordination model

基于人口-经济-环境系统协调发展评价指标体系,通过主成分与耦合协调模型(在耦合模型的基础上进一步深化耦合协调模型)结合,对黄河三角洲高效生态区人口-经济-环境协调发展进行实证分析.研究表明:黄河三角洲人口-经济-环境耦合协调度呈持续上升的趋势,耦合协调类型从勉强协调转化到协调发展,但整体上仍未实现较高的优良协调发展.

This paper using the principal component analysis and the coupling coordination model analyzed the situation of the population economy environment development of the Yellow River delta.based on evaluation index system of population economy ecology,The results showed that the coupling coordination degree raised,and the coupling coordination type has experienced a process of“scrape coordination coordinate development”,but a better coordination has not been achieved.
