长江经济带土地利用冲突时空演变与影响因素OA

The Yangtze River Economic Belt is a strategically important region in China characterized by a dense population,a dynamic economy,and an ecologically sensitive environment,where land use conflicts pose a major challenge to the sustainable development of the Yangtze River basin.Based on the perspective of landscape pattern and functional coordination,this study constructed a land use conflict framework for land use conflict identification,analyzed the spatiotemporal differentiation characteristics of land use conflicts in the Yangtze River Economic Belt from 2005 to 2020,and adopted the geographically and temporally weighted regression(GTWR)model to explore its influencing factors.The results show that:1)from 2005 to 2020,the inter-provincial differences in land use conflict across the Yangtze River Economic Belt were significant,presenting a gradient pattern of"high in the east and west,low in the middle,and concentrated along the river."Moreover,the upper reaches were mainly characterized by structural conflicts,while the lower reaches focused on functional conflicts.2)the land use conflict of the Yangtze River Economic Belt shows an upward trend,and the center of gravity has shifted toward the northeast.Conflicts intensified in both the Chengdu–Chongqing urban agglomeration and the Yangtze River Delta region,while some conflicts in the mountainous areas of the southwestern Belt were alleviated to some extent.3)the annual average temperature,slope,and urbanization rate are the main positive correlation factors,while elevation and sewage treatment rate are the main negative correlation factors.4)The dominant driving factors of land use conflict in the Yangtze River Economic Belt have spatial differences.Based on this,strategies such as regional differentiated regulation and control,dynamic monitoring,and inter-provincial coordination are proposed to provide a scientific basis for the rational utilization and sustainable development of land resources in the Yangtze River Economic Belt.
