黄河流域(甘肃段)水资源与其他自然资源耦合协调关系研究

On the coupling and coordination relationship between water resources andother natural resources in the Yellow River basin (Gansu section)

本文基于黄河流域(甘肃段)2009、2012、2015、2018、2021年57个县级行政区面板数据,利用耦合协调度模型测算并分析了水资源与耕地、园地、林地、草地、湿地的耦合协调关系及时空演变规律。结果表明:①研究期内黄河流域(甘肃段)水资源与耕地、园地、林地、草地、湿地的两两耦合协调关系呈不同发展规律与空间分异特征。总体上,水资源与草地、耕地、园地的耦合协调度相对较高,与林地、湿地的耦合协调度相对较低。②水资源与耕园林草湿整体上呈耦合、协调发展趋势,在空间上呈东北低、西南高的分布特征,在时间变化上未有明显波动。③研究时段内未出现明显的高耦合-高协调演化趋势,表明黄河流域(甘肃段)各类自然资源空间分布和数量分布不均衡,未来应重视设计差异化的自然资源协调发展路径,引导各类自然资源向更有序、协调的方向发展。

This article is based on panel data from 57 county-level administrative regions in the Yellow River basin(Gansu section)in 2009,2012,2015,2018 and 2021.The coupling coordination degree model is used to calculate and analyze the coupling coordination relationship and spatio-temporal evolution law between water resources and farmland,gardens,forests,grasslands and wetlands.The results indicate:①During the research period,the coupling and coordination relationship between water resources in the Yellow River basin(Gansu section)and cultivated land,gardens,forests,grasslands,and wetlands showed different development patterns and spatial differentiation characteristics.Overall,the coupling coordination degree between water resources and grasslands,cultivated land,and gardens is relatively high,while the coupling coordination degree with forests and wetlands is relatively low.②The overall trend of coupling and coordinated development between water resources and cultivated garden grass moisture shows a distribution pattern of low in the northeast and high in the southwest in space,with no significant fluctuations in time.③There was no obvious trend of high coupling high coordination evolution during the research period,indicating that the spatial and quantitative distribution of various natural resources in the Yellow River basin(Gansu section)is uneven.In the future,attention should be paid to designing differentiated natural resource coordination development paths,guiding various natural resources to develop in a more orderly and coordinated direction.
