青海省湟水谷地经济发展与生态环境耦合协调度的时空分异
|
摘要
经济与生态环境的协调有序发展是可持续发展的重要基础,以青海湟水谷地3个典型区县为例,构建了经济发展—生态环境系统的评价指标体系,并运用耦合协调模型分析了2008—2015年两系统的耦合协调度及综合发展水平,最后从时空角度定量揭示出湟水谷地经济发展与生态环境两系统之间相互耦合协调程度及空间分布规律。研究结果表明:(1)2008—2015年湟水谷地经济发展—生态环境耦合协调度总体呈上升趋势,属于良好耦合的中度协调类型,D∈[0.429 4,0.743 8]。(2)空间分布上来看,3个区县的耦合度出现了初级耦合、中级耦合和良好耦合3种状态;耦合协调度出现了轻度失调、濒临失调、勉强协调、初级协调和中度协调5种状态,耦合协调度的变化稍滞后于耦合度的变化。(3)空间组合上,出现了初级耦合濒临失调衰退区、良好耦合轻度失调衰退区、中级耦合濒临失调衰退区、良好耦合勉强协调区、良好耦合初级协调区、良好耦合中度协调发展区6种空间组合类型。总体而言,经济发展对生态环境的胁迫作用和生态环境对经济发展的约束作用是制约整体协调发展水平的主要原因。研究结果为提高青海湟水谷地综合发展质量、协调区域经济发展与生态环境保护提供决策参考。
The coordinated development of economy and ecology is the important foundation for sustainable development.Selecting 3 typical counties of Huangshui Valley of Qinghai Province,we constructed an index system of economy-ecology system.Then we used the coupling-coordination model to analyze economic development and ecological environment system coupling coordination and comprehensive development level from 2008 to 2015.Finally,we quantitatively revealed the coupling coordination degree of economic development and ecological environment,and analyzed the relation coupled spatial distribution and evolution from the space-time point.The results showed that:(1)economic development and ecological environmental system coupling and coordination degree raised in the Huangshui Valley during 2008—2015,while the coordination degree was between 0.429 4 and 0.743 8,generally presenting a moderate coordination of goodcoupling;(2)with respect to spatial variation,there were three states of coupling degrees in 3 counties of the Huangshui Valley in three different years,which were a primary coupling,intermediate coupling and good coupling;the coupling coordinative degree appeared 5 states:mild disorder,teething disorder,forced coordination,primary coordination and moderate coordination,the change of coupling coordination degree lagged behind the coupling degree;(3)with respect to spatial combination,there were 6 kinds of spatial combination types in three typical years in 3 counties of Huangshui Valley,which were primary-teething disorder,good-mild disorder,medium-teething disorder,good-forced coordination,good-primary coordination and good-medium coordination.In short,the contradiction between the development of ecology and economy is the main constraints for the overall level of coordinated development in Huangshui Valley.The results can provide the decision reference for improving the quality of comprehensive development in Huangshui Valley,coordinating the development of regional economy and the protection of ecological environment.
