For mankind’s survival and development,water,energy,and food(WEF)are essential material guarantees.In China,however,the spatial distribution of WEF is seriously unbalanced and mismatched.Here,a collaborative governance mechanism that aims at nexus security needs to be urgently established.In this paper,the Yellow River Basin in China with a representative WEF system,was selected as a case.Firstly,a comprehensive framework for WEF coupling coordination was constructed,and the relationship and mechanism between them were analyzed theoretically.Then,we investigated the spatiotemporal characteristics and driving mechanisms of the coupling coordination degree(CCD)with a composite evaluation method,coupling coordination degree model,spatial statistical analysis,and multiscale geographic weighted regression.Finally,policy implications were discussed to promote the coordinated development of the WEF system.The results showed that:1)WEF subsystems showed a significant imbalance of spatial pattern and diversity in temporal changes;2)the CCD for the WEF system varied little and remained at moderate coordination.Areas with moderate coordination have increased,while areas with superior coordination and mild disorder have decreased.In addition,the spatial clustering phenomenon of the CCD was significant and showed obvious characteristics of polarization;and 3)the action of each factor is self-differentiated and regionally variable.For different factors,GDP per capita was of particular importance,which contributed most to the regional development’s coupling coordination.For different regions,GDP per capita,average yearly precipitation,population density,and urbanization rate exhibited differences in geographical gradients in an east-west direction.The conclusion can provide references for regional resource allocation and sustainable development by enhancing WEF system utilization efficiency. 展开更多

The coordinated development between touristization and urbanization is the key to optimizing regional industrial structure and building a long-term dynamic mechanism for urbanization. Based on constructing the measurement index system of touristization and urbanization level, the evaluation model on the coupled and coordinated degree is used in this paper to measure the inter-provincial pattern of the coupled and coordinated relationship between touristization and urbanization in 31 provinces and autonomous regions in China. The results show that the coupled and coordinated relationship between touristization and urbanization is significantly different in different regions, which presents a gradient decline pattern of the highest in the east, the lower in the middle and the lowest in the west. In the future, measures should be taken to promote the coordinated development between touristization and urbanization in accordance with the regional differences and actual development needs. 展开更多
