摘　　要：建设用地对城市发展、经济发展、提高人居环境有重要影响。选择重庆市巴南区为研究区,以美国陆地卫星遥感数据为数据源,应用3S技术分析重庆市巴南区2000-2015年建设用地扩展速率、扩展强度指数、城市扩展方位、重心转移方向。结果表明:2000-2015年巴南区建设用地扩展为20.87 km^(2),呈正态增长;扩展速度最快为2005-2010年,扩展速率达到2.28 km^(2)/a,最慢为2000-2005年,扩展速率仅有0.36 km^(2)/a;巴南区建设用地主要集中于西部地区,并由西向东方向发展,主要受地形地势影响。建设用地扩展变化特征分析可为巴南区可持续发展提供科学、合理的参考。The built-up land has an important impact on urban development,economic development,and improvement of human settlements.The research area was selected as the Ba’nan District of Chongqing,and the United States Land Rources Satellite data was used as data source.And the 3 S technology was used to analyze expansion rate,index of expansion intensity,location of urban expansion,and direction of barycenter transferring in Ba’nan District of Chongqing from 2000 to 2015.The results show that:from 2000 to2015,the build-up land in Ba’nan District had increased 20.87 km^(2),and showed a normal distribution;the fastest expansion rate was2.28 km^(2)/a in 2005 to 2010,and the slowest expansion rate was only 0.36 km^(2)/a in 2000 to 2005;The build-up land in Ba’nan District is mainly concentrated in the western region and develops from west to east,mainly affected by the terrain.The analysis of the characteristics of the expansion and change of build-up land can provide a scientific and reasonable reference for the sustainable development of Ba’nan District.
