摘　　要：探究土地利用时空演变特征,深入分析土地利用变化趋势,以寻求区域土地资源可持续利用发展路径。以珠江—西江经济带广西段为研究区,基于1995—2022年四期土地利用数据,运用土地利用动态度和土地利用转移矩阵、借助ArcGIS10.8软件对研究区各时期的土地利用时空演变特征进行研究。得出以下结果:①研究区主要以林地和耕地为主,建设用地面积增长最多,共增长1143.38 km^(2),各时期变化率为49.06%、47.81%和21.91%,增幅逐期下降。②1995—2022年,未利用地单一土地利用动态度最大为37.84%,建设用地次之。综合土地利用动态度逐期减小,各地类变化速度减慢。③研究区耕地和林地的相互转化与耕地和林地转为建设用地现象明显。建设用地转入量最大为1192.01 km^(2),且耕地是建设用地增长的主要来源。This paper explores the spatio-temporal evolution characteristics of land use,deeply analyzes the trend of land use change,and seeks the sustainable development path of regional land resources.Taking the Guangxi section of the Zhujiang-Xijiang Economic Belt as the research area,and based on the land use data of the four periods from 1995 to 2022,this paper uses the dynamic attitude of land use and the land use transfer matrix,and the ArcGIS10.8 software to study the spatio-temporal evolution characteristics of land use in each period of the study area.The results are as follows:(1)The study area was mainly composed of forest land and cultivated land,and the construction land area increased the most,with a total increase of 1143.38km^(2),with a change rate of 49.06%,47.81%and 21.91%in each period,and the growth rate decreased gradually.(2)From 1995 to 2022,the single land use dynamic attitude of unused land is the largest 37.84%,followed by construction land.The dynamic attitude of comprehensive land use decreased from period to period,and the change rate of different regions slowed down.(3)The mutual conversion of cultivated land and forest land in the study area and the conversion of cultivated land and forest land into construction land are obvious.The largest amount of construction land is 1192.01km^(2),and cultivated land is the main source of construction land growth.
