| 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。

| Abstract: | 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 urban growth were analyzed combing the index of urban growth rate,urban growth intensity,fractal dimension and compact ratio.Research 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. |
