中国四大城市群水资源生态足迹比较
Comparison of water resources ecological footprint of four major urban agglomerations in China
摘要
Abstract
Urban agglomeration development plays an important role in national economic growth and enhancement of harmoni-ous co-existence between human and nature,and meanwhile it is greatly restricted by water resources.To promote scientific ap-plication of urban agglomerations water resources,based on the ecological footprint theory of water resources,the sustainable utili-zation of water resources in four major urban agglomerations(Beijing-Tianjin-Hebei,Yangtze River Delta,Pearl River Delta and Chengdu-Chongqing)were compared and analyzed using the relevant data of water resources and social-economic develop-ment from 2012 to 2021.The analysis results show that:①In the past 10 years,per capita water resources and production water ecological footprints of four major urban agglomerations are in a downward trend,while per capita domestic water and ecological water ecological footprints are in an upward trend.The ecological footprint of per capita production water accounts for the highest proportion in the study area,exceeding 50%;the lowest proportion is the ecological footprint of per capita ecological water,less than 20%.②Per capita water resources and production water ecological footprint in Yangtze River Delta is the highest,yet those in Beijing-Tianjin-Hebei is in the bottom.After 2015,per capita water resources,production water and domestic water ecologi-cal footprint in Chengdu-Chongqing surpass that in Pearl River Delta.③Per capita water resources carrying capacity in Beijing-Tianjin-Hebei is far poorer than the other clusters,while its per capita water resources stress index and its per capita produc-tion,domestic,ecological water resources stress indexes are much higher than the other clusters.After 2017,per capita water re-sources carrying capacity in Chengdu-Chongqing exceeded that in Pearl River Delta.④Beijing-Tianjin-Hebei cluster is eco-logically in a deficit state,yet water resources in Pearl River Delta and Chengdu-Chongqing are in a state of ecological surplus.Overall,Yangtze River Delta is in a state of ecological surplus.⑤With more efficiency in water utilization,water resources ecolog-ical footprint of per ten thousand yuan GDP has shown a downward trend in all four urban agglomerations.The research results can provide a reference for scientific water utilization and promotion of green and balanced development in urban agglomerations.关键词
