中国水-能源-粮食-生态系统协调发展时空格局及驱动因素研究
Research on the Spatio-Temporal Pattern and Driving Factors of Coordinated Development of China's Water-Energy-Food-Ecosystem
摘要
Abstract
The total consumption of water resources,energy and food in China ranks first in the world and is showing a continuous growth trend.The ecosystem is under great pressure,and how to achieve coordi-nated development between water,energy,food and ecosystem is an important practical issue.By construc-ting a comprehensive evaluation system for water-energy-food-ecosystem,and using methods such as coupling coordination degree model,spatial autocorrelation,center of gravity and standard deviation ellipse,and geo-graphic detector,this study explores the spatio-temporal characteristics,evolution pattern,and driving factors of coupling coordination degree in 30 provinces and cities from 2006 to 2021.The results are as follows.Firstly,the comprehensive development level of water energy food ecosystem in each province and city shows a steady upward trend,with uneven regional development,and the highest development level in the central region.Secondly,the coupling coordination degree of water-energy-food-ecosystem has been increasing year by year,but it is still at a relatively low level,with the coupling coordination degree converging towards high values and the inter provincial gap narrowing.Thirdly,there is a spatial positive correlation effect in the coupling co-ordination degree of water-energy-food-ecosystem,with significant agglomeration polarization effects at high and low values.The center of gravity of coupling coordination is gradually shifting to the southwest in Henan;The eastern center of gravity is shifting southward,and the dispersion trend is increasing;The center of gravi-ty in the central region is shifting towards the northwest,with a prominent agglomeration trend;The center of gravity in the western region is shifting towards the northwest direction,with obvious agglomeration and promi-nent polarization effect.Forthly,the level of urbanization,industrial structure and fixed assets investment have enhanced their role in explaining the development of system coupling and coordination,and the interac-tion value of influencing factors is greater than the independent value of factors.关键词
