摘要
基于2000~2023年土地遥感监测数据,使用地理空间模型对长江经济带上游土地利用功能时空演变进行了定量解析,并对主要影响因素进行了针对性分析.结果表明流域经济带的生活功能面积持续增长,而生产功能面积减少,生态功能面积也减少.生产功能呈北高南低的空间分布,高低值的区域集聚性分布特征显著.生活功能水平由北到南呈高低相间分布,由平原地带向周围山地递减.生态功能水平与地形地貌呈显著相关,功能空间差异明显.主要影响要素包括自然与社会经济因素,其中人口增长与经济发展,农业技术与农业效益推动着土地“三生”功能的时空演变.研究结果对于区域土地利用及协同发展具有参考价值.
Based on land remote sensing monitoring data from 2000 to 2023,this study employed geospatial models to quantitatively analyze the spatiotemporal evolution of land use functions in the upper reaches of the Yangtze River Economic Belt.In addition,a targeted analysis was conducted on the key influencing factors.The results indicate a continuous increase in the area allocated to living functions,whereas areas associated with production and ecological functions have declined.The spatial distribution of production functions exhibits a distinct pattern of being higher in the north and lower in the south,with significant spatial clustering of high and low-value regions.The distribution of living functions alternates between high and low from north to south and decreases from surrounding plains toward mountainous areas.Ecological function levels are significantly correlated with topography and geomorphology,showing pronounced spatial differentiation.The primary influencing factors include both natural and socio~economic variables,among which population growth,economic development,agricultural technology,and agricultural efficiency collectively drive the spatiotemporal evolution of the"production-living-ecological"land use functions.The findings provide valuable insights for regional land use planning and coordinated development strategies.
