摘　　要：国家在2014年推行京津冀一体化政策。为研究石家庄市在京津冀一体化以来的土地利用动态变化及其主要驱动力,本文基于随机森林分类方法获取土地利用数据,使用土地利用变化动态度、土地利用转移矩阵、主成分分析等方法进行分析。结果表明:2014—2016年,石家庄市土地利用变化综合驱动力得分明显提高,经济社会对城市建设的促进作用显著;2016—2018年,石家庄市土地利用变化综合驱动力得分下降,京津冀一体化政策对石家庄市城市化建设的影响逐渐弱化。总体上,2014—2018年土地利用变化明显,主要表现为建设用地的增加和裸地的减少;综合土地利用动态度稳定在13%,裸地的土地利用动态度最高,其变化最剧烈;土地利用类型变化主要集中在建设用地、林地和草地;石家庄市土地利用变化的主要驱动力是人口增长、产业升级和城市建设。The Bejing-Tianjin-Hebei integration policy was implemented by China in 2014.In order to examine the dynamic changes in land use and its primary driving forces in Shijiazhuang following the implementation of this policy,this study acquires the land use data by using the random forest classification method and conducts analyses by utilizing techniques such as the dynamic degree of land use change,land use transfer matrix,and principal component analysis.The results show that from 2014 to 2016,the score of comprehensive driving force of land use change in Shijiazhuang has increased significantly,and the economic and social promoting effect on urban construction is significant.From 2016 to 2018,the score of comprehensive driving force of land use change has decreased,and the influence of Beijing-Tianjin-Hebei integration policy on urbanization construction in Shijiazhuang gradually has weakened.In general,the land use changes from 2014 to 2018 are obvious,mainly manifesting as the increase of construction land and the decrease of bare land.The dynamic attitude of comprehensive land use is stable at 13%,and the dynamic attitude of bare land use is the highest in single land class,and its change is the most drastic.The changes ofland use types mainly focus on construction land forest land and grassland.The main driving forces of land use change in Shijazhuang are population growth,industrial upgrading and urban construction.
