摘　　要：为探究黄河上中游地区水资源利用、低碳排放和绿色发展耦合协调的空间分布、空间格局演变和空间聚集情况,采用耦合协调度模型、标准差椭圆、空间自相关分析方法,分析2010—2020年黄河上中游54个城市水资源利用、低碳排放、绿色发展3个子系统耦合协调的空间异质性。结果表明:1)3个子系统的综合评价指数各有不同程度的提升;各城市的耦合协调度提升程度不同,初级协调城市占比由2010年的55%上升到2020年的74%,中级协调城市较少。2)3个子系统耦合协调度的重心主要迁移方向为西南,标准差椭圆长轴方向为西北-东南,其长轴和短轴的标准差分别减少2.21、0.59 km,有向西南方向迁移的集聚态势。3)3个子系统的耦合协调度在空间上成显著正相关关系,高-高聚集主要分布在黄河中游地区的东南部和西南部,高-低聚集主要分布在兰州市,而低-低聚集主要分布在黄河上游地区的东部;黄河上中游地区3个子系统的耦合协调度虽然逐年提升,但是空间异质性明显。In order to explore the spatial distribution,spatial pattern evolution and spatial aggregation of the coupling and coordination of water 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 northwest-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 aggregation 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.
