| 摘 要： | 以1986、2006年航空遥感影像为基础数据，结合地面调研与农户访问，借助GIS技术分析南宁市边缘区典型样区农用地转换特征及其驱动因素。结果表明：近20年来，研究区农用地类型与结构变化明显，新增畜禽养殖地，农用地中水田、旱地、有林地、灌木林地、草地面积下降；菜地、园地、养殖水面、畜禽养殖地增加，园地、菜地、养殖水面是研究期内增幅较大的地类；农用地转换率平均每年为1．13％，农用地转移主要方向是居民点及工矿用地、交通用地；水田、早地、菜地、园地、灌木林地、草地是农用地转换的主体；农用地空间变化格局以点轴式转换和面状转换为主。城市化、人口增长、经济发展和政策导向是导致农用地利用变化的主要动因。
