长城沿线生境质量与城镇化时空耦合协调及驱动因子研究OA

The coordinated development of urbanization and habitat quality is crucial for sustainable develop-ment,representing a core requirement for Chinese-style modernization.Focusing on 97 cities along the Great Wall from 2000 to 2020,this study integrates the InVEST model,coupling coordination model,and a spatiotem-poral geographically weighted regression model to systematically analyze the spatiotemporal dynamics and driv-ing mechanisms of the coupling and coordination between habitat quality and urbanization.The results reveal the following:(1)Throughout the study period(2000-2020),the macropattern of habitat quality along the region re-mained relatively stable,exhibiting a"high in the east,low in the west"gradient distribution.Concurrently,ur-banization presented a polarized spatial pattern,facilitating development within core urban agglomerations,such as Beijing-Tianjin and Zhengzhou,while driving broader regional development.(2)Temporally,the coupling and coordination degrees between habitat quality and urbanization exhibited a slow upward trend,although the over-all level remained low.The relative development level of certain subregions progressed from a lagging phase to a synchronized or advanced stage.(3)Spatially,the coupling and coordination degree between habitat quality and urbanization manifested a distinct"high in the east,low in the west"differentiation,characterized by a sig-nificant regional imbalance of"high-high and low-low agglomerations".Over time,the"middle collapse"phe-nomenon gradually eased,although the broader system evolution continued to exhibit pronounced path depen-dency.(4)The driving mechanisms of the established coupling and coordination were complex.Precipitation,eco-nomic development,technological innovation,and traffic density were key positive factors,with their marginal impacts exerting pronounced spatiotemporal heterogeneity across the region.Consequently,different regions must establish dynamic assessment and early-warning systems,formulating differentiated coordinated develop-ment strategies based on their local resource endowments and development stages to promote harmonious human-nature coexistence along the Great Wall.
