随着经济不断发展以及全球人口持续增长,建设用地指标紧缺的问题日益凸显,山地城市建设用地扩展研究对于城市的进一步发展有着重要的作用。采用1978—2010年间的8期Landsat-TM数据,通过计算景观分离度、分维数、建设用地动态度、建设用地扩展指数和建设用地重心等指标,对南岸区32年来建设用地扩展过程进行了定量研究。研究结果表明：南岸区建设用地扩展保持较高的速度,城市用地结构更为紧凑,建设用地形态趋于规则化发展,建设用地稳定性也越来越强,且其重心由南岸区的西部向东部迁移。该研究成果对南岸区城市建设与规划具有参考意义。

With continuously economic development and constant growth of global population,the shortage of construction land is more and more serious,and the research on mountainous urban construction land expansion plays an important role in further development of the cities.By using 8 periods Landsat-TM data during 1978-2010,through calculating landscape isolation,fractal dimension,dynamic degree,expansion index,barycenter and so on of construction land,quantitative research is conducted on construction land expansion process in Nanan District in 32 years,and the result indicates that construction land expansion in Nanan District keeps relatively high speed,that urban land-use structure is more compact,that construction land pattern is inclined to standardized development,that construction land stability is more and more strong and that its barycenter transfers toward southeast direction from west of Nanan District.This research result is of important reference significance to urban construction and planning of Nanan District.
