洞庭湖流域城镇化与生态韧性耦合协调研究

Coupling Coordination of Urbanization and Ecological Resilience in Dongting Lake Basin

选取2011-2018年洞庭湖流域28个城市作为研究对象,构建城镇化与生态韧性的综合评价模型和耦合协调度模型,揭示了城镇化与生态韧性的协调关系及演变趋势。实证得出:流域内的城镇化水平和生态韧性水平逐年递增;城镇化子系统中,经济城镇化贡献最大;生态韧性子系统中,抵抗力贡献最大;整体耦合协调度经历了初级协调发展-中级协调发展-良好协调发展3个阶段;各地区协调基础良好,耦合协调度呈现良好协调和中等协调的城市逐渐增多。提出了提升流域城镇化与生态韧性耦合协调度,加快产业绿色化发展进程,推动传统产业绿色转型等相关建议。

This paper selected 28 cities in Dongting Lake Basin from 2011 to 2018 as research objects,constructed a comprehensive evaluation model and coupled coordination degree model of urbanization and ecological resilience,and revealed the coordination relationship and evolution trend of urbanization and ecological resilience.The empirical results show that the urbanization level and ecological resilience level in the basin are increasing year by year;In the subsystem of urbanization,economic urbanization contributes the most;In the ecological resilience subsystem,resistance contributes the most;The overall coupling coordination has experienced three stages:primary coordination development,intermediate coordination development and good coordination development.The coordination basis of all regions is good,and the number of cities with good coordination and medium coordination degree of coupling coordination is gradually increasing.Therefore,this paper puts forward relevant suggestions on improving the coupling coordination degree between urbanization and ecological resilience in river basins,accelerating the process of industrial green development,and promoting the green transformation of traditional industries.
