摘　　要：本文依据2003—2015年间6个时相的影像数据,对富平县城市扩张进行了研究。基于遥感动态监测的城市范围提取方法,确定了各时相的城市范围。然后结合城市扩展速率、扩展强度、分形维数和紧凑度这四个空间特征指数,对城市扩张的数量特征、形态变化和空间特征进行了分析。应用空间分析方法研究了富平县城市的扩张分布和扩张方向,讨论了城市扩张的时空特征,并且分析了其扩张的驱动力。Urban growth in Fuping was studied by examining 6 phases of satellite images from 2003 to 2015. Urbanization was scaled from those sensing monitoring for each of the 6 phases. Thequantitative characteristics, morphology changes and spatial pattern of ur- ban growth were analyzed combing the index of urban growth rate, urban growth intensity, fractal dimension and compact ratio. Re- search on the distribution and direction of Urban growth in Fuping using Spatial Analysis, the spatiotemporal pattern of urban growth was outlined and Its driving force was analyzed.
