摘　　要：选取1992、1997、2002、2007和2013年的DMSP/OLS夜光遥感影像,使用统计数据比较法,提取了闽东南地区城市的建成区,并分析了闽东南地区22 a的城市发展格局和扩展过程.结果表明:闽东南地区22 a期间城市建成区面积增加694.63 km2,扩大6.14倍,呈指数模式增长;22 a内闽东南地区扩展强度表现出显著的递增趋势;建成区扩展以外延型为主,1992-1997年属于"填充增强-外延主导"扩展类型.1997-2002年属于"跳跃增强-外延持续主导-填充为辅"扩展类型.2002-2007年跳跃式扩展继续增强,外延型扩展有所减弱,但仍占主导地位,属于"跳跃增强-外延主导"扩展类型;2007-2013年跳跃式扩展仍然继续增强,外延型扩展继续减弱,属于"跳跃增强-外延型主导"扩展类型.It used statistical data comparison method to ensure optimal thresholds,mapped urban built-up area from the DMSP/OLS nighttime lights data and analyzed the patterns of urbanization processes of southeastern cities in Fujian province. Results showed that. Urban built-up area increased by 694. 63 km2,6. 14 times and as an exponential growth model during the 22 years. The intensity of the southeastern cities of Fujian showed a significant increasing trend. For the urban expansion types,edge-expansion always played a dominant role in the area. Fill-in extensions have been enhanced from 1992 to 1997. Leap growth expansion began to appear during 2002-2007. The leap growth expansion continued to increase from 2002-2013,and edge-expansion was weakened,but still dominated.
