摘　　要：天山北坡位于丝绸之路经济带核心区,其土地利用变化对区域生态保护与可持续发展至关重要。本文基于1990~2020年多期Landsat遥感影像,结合土地利用动态度、转移矩阵及PLUS模型,使用ArcGIS软件分析天山北坡地区土地利用时空演变特征,并探究13个驱动因子对土地利用变化的影响。结果表明,未利用地与草地主要向耕地和建设用地转变;近年来在城市化进程加速和人口增长环境下,耕地面积和建设用地面积扩张明显;人口、GDP及距县政府驻地距离是耕地和建设用地扩张的关键驱动因素。本文为天山北坡地区优化土地利用结构、加强生态保护和推动可持续发展提供科学依据。The northern slope of the Tianshan Mountains is situated in the core area of the Silk Road Econom-ic Belt.The land use changes in this area are of crucial significance for regional ecological protection and sus-tainable development.This paper is based on multi-phase Landsat remote sensing images from 1990 to 2020.By integrating the land-use dynamic degree,transfer matrix,and the PLUS model,and using ArcGIS soft-ware,it analyzes the spatio-temporal evolution characteristics of land use in the northern slope region of the Tianshan Mountains and explores the impacts of 13 driving factors on land-use changes.The results show that unused land and grassland are mainly transformed into cultivated land and construction land.In recent years,with the acceleration of urbanization and population growth,the areas of cultivated land and construction land have expanded significantly.Population,GDP,and the distance from the seat of the county government are the key driving factors for the expansion of cultivated land and construction land.This study provides a scien-tific basis for optimizing the land use structure,strengthening ecological protection,and promoting sustain-able development in the northern slope region of the Tianshan Mountains.
