河南省社会经济和生态环境系统协调发展的耦合分析

Coupling Analysis of Coordinated Development of Social Economy and Ecological Environment System in Henan Province

社会经济发展和自然生态环境之间的耦合分析一直是可持续发展研究的热点话题,本文以2010—2019年河南省为研究对象,采用耦合协调度模型研究社会经济发展和自然生态环境之间的耦合程度及变化趋势。研究结果显示:2010—2019年间河南省社会经济发展水平、耦合度C、系统综合发展指数T呈线性上升趋势;自然生态环境效益函数呈U形趋势;社会经济和自然生态环境的耦合协调度水平处在0.2333~0.6438之间,经历了从中度失调到轻度失调到濒临失调再到初级协调的过程,整体在向好的方向转变。但是对生态环境的利用水平相对来说还是较低,两个系统之间的协调发展水平有待进一步提高。

General Secretary Xi Jinping put forward the concept that"clear water and green mountains are mountains of gold and silver"during his inspection tour in Anji,Zhejiang Prov⁃ince in 2005.Later,he put forward the"Five Pursuits"of green development,emphasizing the mutual relationship between economic development and ecological environmental protection.Henan Province occupies an important strategic position in the overall development of our na⁃tion,and the green economy is developing towards a good trend.But there are still some short⁃comings and weak links in the whole process.Therefore,studying the level of coordination be⁃tween natural ecological environment and social economy in Henan Province is important for im⁃plementing sustainable development strategy and further management of natural ecological environment in Henan Province.With the data of Henan Province from 2010—2019,this paper con⁃structs a comprehensive evaluation index system based on the connotation of natural ecological environment and socio-economic development.The natural ecological environment system in⁃cludes three levels:the supply of natural resources,the pressure of ecological environment and the condition of environment.The socio-economic system selectes a total of 22 indicators from three levels:social development level,economic development level and social welfare level.Prin⁃cipal component analysis(PCA)and coupling coordination degree model were used to measure the coupling degree and change trend between natural ecological environment and socio-eco⁃nomic development in Henan Province.The results show that:①From the perspective of devel⁃opment status,the level of social organization and management in Henan Province from 2010—2019 has been constantly improved,and the social economy has been developing continuously,and environmental situation has improved.②From the perspective of socio-economic benefit function,the level of social development in Henan Province during 2010—2019 showed a linear upward trend,especially after 2016,the growth rate sped up;From the perspective of natural eco⁃logical environment benefit function,the development of natural ecological environment in Henan Province showed a decreasing trend during 2010—2013,and then rose slowly after 2014.③From the perspective of evaluation results of coupling coordination degree,the coupling be⁃tween natural ecological environment and socio-economic development in Henan Province from 2010—2019 has changed from weak coupling to moderate coupling,and the coupling process be⁃tween them is developing steadily from running-in stage to a higher level of orderly state.From moderate imbalance to primary coordination,the comprehensive level is developing toward a fa⁃vorable trend.④In terms of development status,Henan Province changed from lagged socioeconomic development to lagged ecological environment during the decade of 2010—2019.Based on the research results,this paper puts forward relevant countermeasures and suggestions:pay attention to the restoration and improvement of ecological environment,strengthen environ⁃mental governance and pollution treatment,strengthen urban and rural infrastructure construc⁃tion,increase R&D investment and encourage scientific and technological innovation,promote the optimization and upgrading of industrial structure.Through further ecological and environ⁃mental management,Henan Province’s social and economic transformation will be promoted to green development.
