摘　　要：运用土地利用动态度、土地利用程度综合指数和地理探测器等方法分析2009-2019年玉门市土地利用时空变化特征及其驱动力因子。结果表明,研究期间玉门市未利用地面积持续减少,其余土地利用类型的面积均有所增加;土地利用类型的转换集中在城镇村及工矿用地、耕地和未利用地之间。玉门市土地利用程度处于发展时期,但土地利用程度不高,园地、草地、林地、水域和交通运输用地变化强度较大。2009-2019年玉门市土地利用时空变化较为明显,人口、GDP及与政策因素的交互是该区域土地利用变化的主要驱动力。This paper analyzed the spatial-temporal variability characteristics and its driving factors of land use in Yumen City based on land land-use dynamic degree,land degree comprehensive index and GeoDetector model.The results showed that during the study period,the area of unused land continually decreased,while other land use types were increased.The conversion between various land types in Yumen City from 2009 to 2019 was mainly between urban village and industrial land,cultivated land and unused land.The result of land degree comprehensive index indicated that Yumen City is in a period of development,but the land degree comprehensive index was not high.Among the types of land use,the dynamics of gardens,grassland,woodland water area and transport land was the larger.There was a notable spatial-temporal variability characteristics of land use in Yumen City from 2009 to 2019,population,GDP and interaction with policy factors are the main drivers of land use change in the region.
