【摘要】 基于DMSP-OLS夜间灯光数据,运用空间统计分析方法,对山东县域经济发展的时空特征进行了研究。结果表明:1)区域单位面积GDP与单位面积灯光数据具有显著的相关性; 2) 20多年来县域GDP普遍增长,但经济发展空间不平衡特征没有完全扭转; 3)山东省县域GDP在研究期的后半段比前半段具有更高的增长率,在半岛地区尤为突出。本研究重建了山东省1992—2013年间的县域经济发展时空格局,并揭示了单位GDP相对能耗的时空差异,可为山东省县域经济发展政策的制定提供一定的指导。更多还原

【Abstract】 Based on the DMSP-OLS nighttime lighting data,the spatial and temporal characteristics of the economic development in Shandong counties were studied using spatial statistical analysis methods. The results show that:( 1) There is a significant correlation between GDP per unit area and unit area light data.( 2) The county GDP has generally increased for more than 20 years,but the spatial imbalance of economic development has not been completely reversed.( 3) The county GDP has a higher growth rate in the last 11 years than in the previous 10 years of the study period,especially in the peninsula. The study reconstructed the pattern of economic development of the county of Shandong Province during 1992—2013 and revealed the temporal-spatial differences of energy consumption per unit GDP. It will be helpful to the study of county economy development in Shandong province.更多还原
