The Pan-Pearl River Basin is a bridgehead for China's reform and opening-up and the construction of the Belt and Road at Sea, with vital strategic significance in Chinese overall development. Land use data and climate and socio-economic indicators were integrated to probe the spatiotemporal change and its driving forces of land use in the Pan-Pearl River basin with ArcGIS spatial analysis tool and SPSS factor analysis tool. Results showed that land use in the Pan-Pearl River Basin significantly changed between 1990 and 2015, with decreases of the area of paddy field and woodland and rapid increases of urban land and other construction land. Outflow of grassland occurred in the northwestern part of the basin. Reduction of cultivated field was mainly concentrated in the central part of the basin and coastal areas. Increases in urban and rural land, industrial and mining land, and residential land were centrally distributed in the Guangdong-Hong Kong-Marco Greater Bay Area. The prominent change areas were Guangdong-Hong Kong-Marco Greater Bay Area : central and southeast of Guangxi Province : northern Hainan Province. Land use changes during 1990-2000 were most obvious in the basin. The main driving factor of spatiotemporal variation of land use was the rapid development of social economy and industry and the improvement of residents' consumption level.
泛珠江流域是中国改革开放和海上丝绸之路建设的桥头堡，在中国整体发展中具有至关重要的战略意义。利用ArcGIS空间分析工具和SPSS因子分析工具，整合土地利用数据以及气候和社会经济指标，以探究泛珠江流域土地利用的时空变化及其驱动因素。结果表明，1990年至2015年间，泛珠江流域土地利用发生了显著变化，水田和林地面积减少，城市用地和其他建设用地迅速增加。流域西北部出现草地流出。耕地减少主要集中在流域中部和沿海地区。城乡用地、工矿用地和居住用地的增加集中分布在粤港澳大湾区。显著变化区域为粤港澳大湾区、广西壮族自治区中部和东南部、海南省北部。1990 - 2000年期间流域内土地利用变化最为明显。土地利用时空变化的主要驱动因素是社会经济和工业的快速发展以及居民消费水平的提高。
