黄河上中游地区水资源利用、低碳排放和绿色发展协调性
Study on the Coordination of Water Resources Utilization,Low-Carbon Emission and Green Development of the Middle and Upper Yellow River
摘要
Abstract
In order to explore the spatial distribution,spatial pattern evolution and spatial aggregation of the coupling and coordination of wa-ter resources utilization,low-carbon emission and green development of the Upper and Middle Yellow River,coupling coordination degree model,standard deviation ellipse and spatial autocorrelation analysis method were used to analyze the spatial heterogeneity of the coupling and coordination of water resources utilization,low-carbon emission and green development in 54 cities of the Upper and Middle Yellow River from 2010 to 2020.The results show that a)the comprehensive evaluation index of the three subsystems has been improved to varying degrees and the degree of coupling and coordination of each city is different.The proportion of primary coordination cities has increased from 55%in 2010 to 74%in 2020,and there are fewer intermediate coordination cities.b)The main migration direction of the center of gravity of the coupling coordination degree of the three subsystems is southwest,and the direction of the long axis of the standard deviation ellipse is north-west-southeast.The standard deviation of the long axis and the short axis is reduced by 2.21 km and 0.59 km,respectively,and there is a gathering trend of migration to the southwest.c)The coupling coordination degree of the three subsystems has a significant positive correlation in space.The high-high aggregation is mainly distributed in the south and west of the middle reaches of the Yellow River,the high-low aggre-gation is mainly distributed in Lanzhou City,and the low-low aggregation is mainly distributed in the west of the upper reaches of the Yellow River.Although the coupling coordination degree of the three subsystems of the Upper and Middle Yellow River has been increased year by year,the spatial heterogeneity is obvious.关键词
