Coupling and Coordination of Land Use Efficiency and Land Ecological Security in Jiziwan Metropolitan Area of the Yellow River
By analyzing the spatiotemporal evolution characteristics of land use efficiency and land ecological security in the Yellow River Jiziwan metropolitan area,this study explores the path of coordinated development between land use and ecological security in the Yellow River Basin.Using the Super-SBM model,projection pursuit model,and coupling coordination model,15 cities in the Yellow River"Jiziwan"metropolitan area from 2002 to 2021 were selected as research objects to evaluate their land use efficiency,land ecological security level,and the coupling coordination between the two.The results showed that the land use efficiency was good during the research period,with an average value of 0.991,showing an overall downward trend year by year,with Ordos as the high-level agglomeration center in space;the overall level of land ecological security is stable,with an average value of 2.012,with Ordos and Yulin as high-level gathering centers in space;the average coupling coordination between the two is 0.616,which is at a low level of overall coordination.Most cities are on the brink of imbalance,showing a spatial distribution characteristic of"high in the center and low in the surrounding areas".There is a clear contradiction between land use efficiency and land ecological security.Therefore,cities within the Yellow River Jiziwan metropolitan area should optimize land allocation,improve land use efficiency,strengthen experience sharing and coordinated development between cities,jointly build a differentiated industrial pattern,and promote high-quality development of Jiziwan of the Yellow River.
