摘　　要：随着东莞市经济和城镇化的快速发展,东莞市的土地利用格局发生了较大的变化。为探讨东莞市土地利用时空变化特征及其背后的驱动因素,该研究使用2000、2005、2010、2015和2020年5个时期的土地利用现状数据,分析东莞市近20年来土地利用类型的结构、变化幅度和迁移方向特征,并用地理探测器模型对造成东莞市土地利用时空变化的驱动因素进行定量研究。结果表明:(1)2000—2020年期间,东莞市耕地和林地的面积分别减少了425.71 km^(2)和225.9 km^(2);建设用地规模持续扩张,总面积共增加了680.20 km^(2),主要由耕地和林地转化而来;相比之下,草地、水域和其他土地发生的变化较不显著。(2)各个驱动因子对东莞市近20年的土地利用变化产生了不同程度的影响,其中距城镇中心的距离、距主要道路的距离、年均降水量、年均气温和高程为其主要驱动因素;各因子交互探测均表现出双因子增强的效果,这表明多种因子的共同作用加剧了东莞市土地利用变化。With the rapid development of Dongguan's economy and urbanization,the land use pattern has significantly changed.To explore the spatial-temporal characteristics and driving factors of land use changes of Dongguan,this study analyzes land use structure,change range and transformation di-rection of Dongguan over the past 20 years based on the current land use data in the years 2000,2005,2010,2015 and 2020.Quantitative analysis with the geographic detector was also implemented to the driving factors of land use change in Dongguan.The results show that:During 2000-2020,the area of cultivated land and forest land in Dongguan decreased by 425.71 km^(2)and 225.9 km^(2)re-spectively;the construction land continued to expand with a total area increase of 680.20 km^(2),main-ly transferred from the cultivated land and forest land;in contrast,the area of grassland,water,and other land changed to less extent.②The driving factors have had different influences on land use changes in Dongguan in these 20 years,but the distance from town centers,the distance from major roads,average annual precipitation,average annual temperature and elevation are the main factors;moreover,the interaction between all factors shows a dual-factor enhancement which indicates that the interaction has intensified the land use changes in Dongguan.
