摘要
选取1979、1989、1999和2006年四期MSS/TM/ETM+遥感影像对哈大齐城市建成区进行了扩展监测,并借助年均扩展指数、紧凑度、分维数和空间自相关指数Moran’I对扩展特征进行了分析。结果表明,哈大齐城市带建成区面积从1979年的290.29km2扩展到2006年的553.98km2,整体扩展速度逐年加快,但大庆组团扩展速度逐年降低;受20世纪90年代东北老工业基地衰退和2003年后东北振兴政策的影响,紧凑度和分维数存在一定波动;除大庆组团呈现离散结构外,哈尔滨组团和齐齐哈尔组团空间结构均未呈现集聚或离散特征,城市带发育仍处于低级阶段。
Four periods of MSS/TM/ETM+ remote sensing images in the year of 1979,1989,1999 and 2006 were selected to detect expansion change in HaDaQi city build-up area,and its expansion characteristics was analyzed by means of EI(expansion index per year),compactness,fractal dimension and spatial autocorrelation index(Moran'I).The result showed that build-up area of HaDaQi city belt changed from 290.29km2 to 553.98 km2,its expansion intensity was increased while Daqing group was decreased ;the compactness and fractal dimension were fluctuated by the influence of old industry degradation in 1990s and reforming policy after the year 2003; spatial autocorrelation analysis showed that Daqing group displayed disperse pattern while Haerbin group and Qiqihaer group displayed no clustered or dispersed pattern,and the whole city belt of HaDaQi still in the primary phase.
