宁夏区域发展对环境胁迫的时空演变及驱动机制分析
Spatiotemporal evolution and driving mechanism of environmental stress of regional development in Ningxia Hui Autonomous Region
摘要
Abstract
Environmental stress caused by regional development has emerged as a critical impediment to the high-quality development of the Yellow River Basin.The Ningxia Hui Autonomous Region,located in the upper reach-es of the Yellow River,holds significant ecological status.This study focuses on the Ningxia Hui Autonomous Re-gion,establishing an environmental stress evaluation index system and utilizing the entropy method to systemati-cally calculate the environmental stress index(ESI)across various counties in Ningxia.The results show that dur-ing 2012-2020,the minimum ESI value in the county level of Ningxia increased from 0.056359 to 0.091005,the maximum value decreased from 0.948896 to 0.911162,and the average ESI value in the county level of Ningxia decreased from 0.56580 to 0.49762.Overall,Ningxia's environmental stress level has improved,and the local environmental stress is still tight.Moran's I index analysis showed a significant spatial correlation between environmental stress during 2012-2020,and the spatial spillover effect of regional development on environmen-tal stress increased,with the spatial aggregation effect becoming more obvious.In addition,the Getis-Ord G*in-dex analysis demonstrated that the distribution of hot and cold spots of environmental stress correlated with eco-nomic and social development levels.This paper selected a geographically weighted regression model that could better reflect the change in variable regression coefficient with the trend of geographical location for analysis to identify factors affecting the spatial distribution of environmental stress in Ningxia.The results show that popula-tion,urbanization,and energy consumption positively affect environmental stress,while industrial structure and land use have negative effects.Therefore,Ningxia should constantly improve population quality,orderly promote the rational distribution of the population in space,implement a new urbanization strategy,and improve urbaniza-tion quality.In addition,Ningxia should make technological improvements to energy-intensive and high-polluting industries to reduce pollutant discharge,accelerate the upgrading of the industrial structure,optimize the land use structure,and continuously raise resource utilization efficiency.关键词
