摘要
宁夏是西北地区重要的生态安全屏障,生态环境相对脆弱、产业结构偏重,生态保护压力与发展不足问题同时存在。研究经济高质量发展与生态环境保护耦合关系,对于宁夏推进黄河流域生态保护和高质量发现先行区建设具有重要意义。基于省域和县域两种不同研究尺度,构建了差异化的经济高质量发展和生态环境保护指标体系,综合运用熵值法、耦合协调度及空间自相关分析等方法,对宁夏近10年来的经济高质量发展、生态环境保护及两者协调耦合关系进行了时空双维度分析,全面分析其变化规律及分布特征。结果表明:宁夏经济高质量发展和生态环境保护均呈现出整体提升的良好发展趋势,两者之间的协调耦合关系从濒临失调逐步转变为良好协调状态;宁夏经济高质量发展和生态环境保护存在显著的正向空间自相关关系,呈现出不同程度的高—高、低—低集聚和高—低分异特征;沿黄生态经济带和中、南部地区各县(市、区)在经济高质量发展和生态环境保护方面呈现出截然相反的空间分布特点。基于研究结果,提出加强创新驱动、推动产业转型升级;坚持生态优先、加强生态环境保护;推进制度改革、扩大对外开放的建议。
As an important ecological security barrier in Northwest China,Ningxia has a fragile ecological environment and a heavy industrial structure,ecological protection pressure and insufficient development exist at the same time.Studying the coupling relationship between high-quality economic development and ecological environmental protection is of great significance for Ningxia to promote the ecological protection of the Yellow River Basin and the construction of high-quality discovery pilot area.Based on provincial and county research scales,this study builded a differentiated index system for high-quality economic development and ecological and environmental protection,and comprehensively used the methods of entropy method,coupling coordination degree and spatial autocorrelation analysis to analyze the high-quality economic development,ecological environmental protection and their coordinated coupling relationship in Ningxia in recent 10 years.The results revealed that:High-quality economic development and ecological and environmental protection in Ningxia had shown a good development trend of overall improvement,and the coupling relationship between them had gradually changed from being on the verge of imbalance to a good coordination state;There was a significant positive spatial autocorrelation between high-quality economic development and ecological environment protection in Ningxia,and showed the characteristics of high-high,low-low agglomeration and high-low differentiation;The counties along the Yellow River Ecological Economic Belt and the counties in the central and southern regions showed diametrically opposite spatial distribution characteristics in terms of high-quality economic development and ecological environment protection.Based on the research results,the paper puts forward three suggestions:strengthening innovation drive and promoting industrial transformation and upgrading;adhere to giving priority to ecology and strengthening ecological environment protection;promoting institutional reform and opening wider to the outside world.
