河南省各地级市经济与环境耦合关联分析

Coupling and Correlation of Economy and Environment in Henan Province

探究河南省各地市经济与环境因子相互作用情况,旨在全面认清各市经济与环境的耦合度现状,为各区域政策的制定与调整提供借鉴,实现河南省经济与环境的协调发展。基于对河南省18市2008—2012年各项指标数据,运用灰色关联分析法构建出区域经济与环境内部各因子相互作用的关联度模型和耦合度模型,用定量方法分析经济与环境系统耦合的主要因素,并从时间和空间两个角度分析两者之间的关系。结果表明,河南省各地市经济发展对生态环境的胁迫作用以及生态环境对经济发展的约束性都较大,其中环境建设和环境治理对经济发展的约束性最大,而经济结构和经济实力对生态环境胁制作用最大。河南省各地市经济与环境耦合度空间分异规律显著,大致将其划分为协调、磨合、拮抗和低水平耦合4种类型,其中以磨合、拮抗类型为主;2008—2012年河南省各地市经济与环境耦合度总体呈上升趋势,但期间耦合度时序变动较大。

In order to provide a reference for the regional policy making and realize the harmonious development of economy and environment in Henan Province, the interaction between economic andenvironmental factors of the cities in Henan Province was explored to comprehensively identify the cities＇ coupling status of economy and environment. Based on the data of 18 cities in Henan Province from 2008 to2012, the correlation degree model and coupling degree model between economy and environment were builtby using gray correlation analysis. Quantitatively analysis was conducted to analyze the main influencing factors and the correlation of the economy and environment system from the aspects of both time and space.The results showed that both the stress effect of economic development, especially economic structure andstrength, on the ecological environment and the binding force of ecological environment, especiallyenvironmental construction and management, on economic development were larger in Henan Province. Spatialvariation of economy and environment coupling degree of cities in Henan Province was significant with 4 typeswhich were coordination, less coordination, antagonism and low-level coupling, among which less coordinationand antagonistic were two main types. Coupling degree of economy and environment of Henan Province was increasing from 2008 to 2012 with a relative large fluctuation.
