摘　　要：[目的]揭示山东半岛蓝色经济区城市土地经济密度时空差异特征,为统筹该区域土地利用提供参考。[方法]利用变差系数、空间自相关等方法对山东半岛蓝色经济区36个县(区)在2005—2011年的城市土地经济密度时空差异特征进行研究。[结果](1)山东半岛蓝色经济区平均城市土地经济密度由5.46亿元/km2增长到9.72亿元/km2,总体呈不断上涨趋势,但城市间土地经济密度差异明显,其高值点主要集中在蓬莱市、龙口市和招远市形成的空间集聚区;(2)城市间土地经济密度的区域动态差异呈不断减小趋势,相对发展速率存在明显差异,其中龙口市最高,蓬莱市最低,且呈负向发展态势;(3)土地经济密度在整体空间分布格局上差异不断减小,局域的集聚中心由荣成市和文登市移动到蓬莱市、龙口市和招远市。[结论]山东半岛蓝色经济区城市土地经济密度空间分布不均,整体上东部城市土地经济密度明显高于西部城市。[Objective] Investigating the temporal-spatial difference features of urban land economic density of the blue economic zone in Shandong Peninsula in order to provide a sensible planning for land use pattern. [Methods] Data was collected from urban land economic density of blue economic zone（thirty-six countrylevel cities） in Shandong Peninsula during 2005--2011. Coefficient of spatial variation and autocorrelation were used. [Results] （1） The average density of urban land economy showed a rising trend, increasing from 546 million yuan/km^2 to 972 million yuan/km^2. Urban land economic density among cities had significant differences, the higher values of land economic density located in Penglai, Longkou and Zhaoyuan City; （2） Regional differences of land economic density dwindled, comparatively there were significant differences in relative development efficiency for all cities. The highest relative development efficiency was in Longkou City; Penglai was the lowest and it also showed a negative development as compared with others; （3） The spatial differences of land economic density reduced gradually, and the spatial centralization had converted from Rongeheng and Wendeng City to Penglai, Longkong and Zhaoyuan City. [Conclusion] It showed the distributional pattern was uneven, and the trend was increasing on the urban land economic density of blue economic zone in Shandong Peninsula, and the value was comparatively higher in the east than that in the west.
