青藏高原生态环境与经济社会发展耦合协调水平的时空演化及障碍因子分析

Spatiotemporal Evolution and Obstacle Factor Analysis of the Coupling and Coordination Level Between the Ecological Environment and the Economic and Social Development of theQinghai-Tibet Plateau

独特的地理环境决定了青藏高原生态环境与经济社会发展耦合协调的重要意义。文章从生态、经济和社会三个子系统出发,构建了9类27个指标的生态环境与经济社会发展耦合协调评价指标体系,基于2013—2022年共计5130个样本数据,运用耦合协调度模型、莫兰指数和障碍度模型对青藏高原生态环境与经济社会发展耦合协调度、空间格局和障碍因子进行了定量分析。结果表明:(1)青藏高原生态环境与经济社会发展耦合协调水平整体发展良好;(2)青藏高原生态环境与经济社会发展耦合协调空间关联性良好,协调重心以区域东北部为主;(3)青藏高原生态环境与经济社会发展耦合协调的障碍因子是经济发展。基于此,青藏高原未来应在做好生态环境保护的基础上持续推动经济发展绿色转型,充分发挥高耦合协调地区辐射带动作用,进而实现区域生态环境与经济社会发展高水平耦合协调。

The unique geographic environment determines the significance of coupling and coordinating the ecological environment and economic and social development in the Qinghai-Tibetan plateau.Starting from the three subsystems of ecology,economy and society,the article constructed an evaluation index system of coupled coordination of ecological environment and economic and social development with 9 categories and 27 indexes,and based on a total of 5,130 sample data from 2013 to 2022,the coupled coordination degree model,Moran index and obstacle degree model were applied to the degree of coupled coordination of ecological environment and economic and social development on the Qinghai-Tibetan Plateau,spatial pattern and obstacle factors were quantitatively analyzed.The results show that:(1)The level of coordination between the ecological environment and economic and social development on the Qinghai-Tibetan Plateau has developed well overall;(2)the spatial correlation of the coupling and coordination between the ecological environment and economic and social development on the Qinghai-Tibetan Plateau is good,and the center of gravity of the coordination is dominated by the northeastern part of the region;(3)The obstacle to the coupling and harmonization of the ecological environment and economic and social development on the Qinghai-Tibetan Plateau is economic development.Based on this,the Qinghai-Tibet Plateau should continue to promote the green transformation of economic development on the basis of good ecological and environmental protection,and give full play to the role of radiation driven by the highly coupled and coordinated region to realize the high level of coupled and coordinated regional ecological environment and economic and social development.
