乡村产业发展与生态系统健康耦合协调的时空格局及其驱动机制OACHSSCD

The mutual empowerment and coordinated advancement of rural industrial development(RID)and ecosystem health(EH)are inherent to rural revitalization.Based on an analysis of the coupling coordination mechanism between RID and ESH,this study comprehensively applied methods including subjective-objective combined weighting,the VORS model,the coupling coordination degree(CCD)model,the optimal parameters-based geographical detector(OPGD),and multiscale geographically weighted regression(MGWR)to reveal the spatiotemporal evolution and driving mechanisms of the coupling coordination between RID and EH in the Yangtze River Economic Belt(YREB)from 2000 to 2023.The results demonstrate that:1)During the study period,the RID in the YREB upgraded from a low level to a relatively low level,exhibiting a spatial gradient characteristic of downstream＞midstream＞upstream.EH remained at a moderate level,presenting a temporal trajectory of an initial decline followed by a subsequent rise,and a spatial pattern characterized by both a higher in the south,lower in the north macro-differentiation and a feature of midstream＞upstream＞downstream basin.2)The CCD of the two systems steadily increased,transitioning from a mild maladjustment to a basic coordination stage,although significant differences existed among the upper,middle,and lower reaches.Its spatial characteristics were similar to the EH pattern,and the spatial extent of the four major maladjustment agglomerations:western Sichuan,Chengdu-Chongqing,central Hubei-northern Hunan,and Anhui-Jiangsu,continued to shrink.3)The proportion of forest land,land use intensity,population density,and road network density were the primary factors affecting the CCD,overall exhibiting a distinct east-west zonal spatial differentiation.4)Problematic areas of coordinated development were mainly distributed in the northern part of the economic belt,predominantly driven by a unidirectional lag in either EH or RID.Based on these findings,we propose targeted strategies,aiming to provide scientific references for the coordinated development of rural industry and ecosystem health in the YREB.
