城镇化与生态环境耦合协调发展研究

Study on Coupling and Coordinated Development Between Urbanization and Eco-environment

构建城镇化与生态环境系统的综合评价指标体系,利用2006—2016年的湖北省相关数据对系统的综合水平进行测度,借用耦合协调度模型对湖北省城镇化和生态环境系统的耦合协调程度的时间演变特征及协调发展关系进行研究。结果表明,随着湖北省城镇化系统综合评价指数的提高,生态环境系统综合评价指数先上升后下降再上升,经历倒"U"型变化过程;湖北省城镇化与生态环境系统发展的耦合度一直处于拮抗状态,协调度虽然逐渐提高并呈现出良性发展趋势,但协调度等级较低。

This study aims to propose a comprehensive index system for the assessment of urbanization and the eco-environment.Making reference to physical coupling models,we developed a coupling coordination degree model to examine the relationship between urbanization and the eco-environment in Hubei province based on the data from 2006 to 2016.The conclusions are as follows:With urbanization comprehensive index’s going up,Eco-environment comprehensive index increases firstly then decreases and then increases,presenting Inverted“U”“U”evolution trend;the coupling relationship of urbanization and the eco-environment in Hubei province has always been in rivalry phase.Coupling harmonious degree is gradually raised and presents a virtuous developing trend,but the evolution of harmonious is in low-levelly.
