摘　　要：省域城镇扩展格局的研究对协调区域内各城市发展具有促进作用。研究基于校正后的1992年、1997年、2002年、2007年及2012年福建省DMSP/OLS夜间灯光数据,运用区域平均灯光强度指标、标准差椭圆及景观格局指数分析福建省城镇扩展时空演变格局特征。研究发现福建省城镇化态势呈现一定的近海性,从内涵式向外延式转变,具体表现为由东南沿海向西北内陆递减趋势,且城镇化水平差异及省域内部扩展差异性逐步增强,景观破碎度增大。The researches on provincial urban expansion pattern can promote the coordination of urban development in the region.Based on the corrected DMSP/OLS night lighting data of Fujian in 1992,1997,2002,2007 and 2012,the spatial and temporal development pattern of urban expansion over time in Fujian was analyzed with the calculation of average light intensity,standard deviational ellipse and landscape indices.The results show that the urbanization trend of Fujian shows a certain degree of offshore,and the gap of urbanization is reducing from the southeast coast to the northwest inland.Besides,the urban expansion pattern has shifted from inward integration to outward expansion,with increased landscape fragmentation.
