摘　　要：基于遥感数据、地形图和统计数据提取城市用地信息，采用指数分析、GIS空间分析和地统计分析方法研究了1954年、1975年、1986年、2000年和2005年5个时期辽中群组型城市用地特征。结果表明：1954年以来城市用地不断增加，1954～1975年城市扩张最快，但不同城市扩张速率和趋势不尽相同；1986～2005年城市间的相互作用强度成倍增加，城市化发展的空间辐射作用增强，沈阳市作为区域中心城市，城市化水平和作用不断突显，一些城市明显向沈阳市方向移动；1975～2000年小城镇快速发展；较高城市空间年增长率分布区域与城市重心转移方向基本吻合。并分析了成因。The urban land information of central Liaoning province in 1954, 1975, 1986, 2000 and 2005 was extracted with the remote sensing images, relief maps and statistical data, and the spatial pattern characteristics, the spatial - temporal changes of these urban lands as well as their causes were studied with the help of index analytic method, GIS spatial analysis and geographical statistics function. The results show that, since the early 1950s, the urbanized land in the study area has been increased continually, and the urban expansion was the fastest from 1954 to 1975, with different cities having different expansion rates. From 1986 to 2005, the function intensity between cities was growing geminately, the spatial radiancy function of urbanization was enhanced, the trend of regional urban development of cities was obvious, and the function of Shenyang as the central city in this highly urbanized area became distinct, with other cities in the area moving towards Shenyang. From 1975 to 2000, small towns developed rapidly. The spatial distribution of relatively high annual urban growth rate was consistent with the direction of the urban center transfer. The causes for these changes are also analyzed in this paper.
