摘　　要： 为了研究县域城镇体系空间结构的变化及其影响,以博罗县和惠阳区为研究区域,对其1999年、2003年和2009年3个时期的Landsat遥感影像进行解译。并基于分形理论,运用空间关联维数、聚集维数及欧氏空间分形维数,对它们的城镇体系和土地利用空间形态进行测算,从时间和空间上进行对比分析探讨。结果表明:两县(区)城镇体系各要素空间分布的相互作用越来越强,向心聚集度下降;其中因地形条件和经济区位的差异,地形复杂区(博罗县)的空间相关性更强,而平原区(惠阳区)则是聚集度更大。同时,土地利用的空间形态变得更为复杂,建设用地变化尤为明显,使林地和耕地遭到严重的破坏,区域内的下垫面景观格局变得更加破碎。 For the purpose of studying the variation and influence of the spatial structure of county urban system, Boluo County and Huiyang District are studied and the Landsat remote sensing images over three period during 1999 to 2009 are interpreted. In addition, on the basis of fractal theory, using the spatial correlation dimension and the aggregation dimension of urban system and measuring the Euclidean fractal dimension of spatial form of land utilization, a comparative analysis on time and space is discussed. The results show that the interaction of the spatial distribution of the elements of urban systems in two counties（districts） is much stronger and the centripetal aggregation degree is declined. Furthermore, because of the differences in topographic condition and economic zone, the spatial correlation in complex terrain（Boluo County） is stronger while the aggregation degree in plain terrain（Huiyang District） is higher. Over time, spatial form of land utilization becomes more complex; the construction land which destroys the forest and arable land, makes the surface landscape in the areas more fragmentary.
