摘　　要：基于1998年、2003年、2008年和2013年DMSP/OLS夜间灯光数据,选用加权标准差椭圆、引力模型与社会网络分析等方法,对淮海经济区经济空间格局演化与城市中心性进行测度。研究结果表明:1)淮海经济区经济总体水平较低,各地市经济发展水平差异显著,苏北和鲁南地区经济水平明显优于豫东和皖北地区,徐州市经济发展质量最优;2)城市间经济联系呈现以徐州市为中心,以济宁市、临沂市和枣庄市为重要节点的放射状分布,经济区边缘城市与外部的经济联系强度最弱;3)徐州市作为淮海经济区的中心城市,对周边城市有很好的经济引领作用,但尚不能对位于该区域边缘地带的城市形成较强的辐射和带动作用,其作为中心城市的带动力仍有较大提升空间。Based on DMSP/OLS night-time light(NTL)remote sensing images in 1998,2003,2008 and 2013,the evolution of economic spatial pattern and urban centrality of Huaihai Economic Zone were measured by using weighted standard deviation ellipse,gravity model and social network analysis,etc.The results show that:1)The overall economic level of Huaihai Economic Zone is relatively low,and the economic differences among different cities are significant.On the whole,the economic level of Northern Jiangsu and Southern Shandong is obviously better than that of Eastern Henan and Northern Anhui,among which the economic development quality of Xuzhou City is the best.2)Economic linkages between cities show a radial distribution taking Xuzhou as the center,Jining,Linyi and Zaozhuang as important nodes,and the economic connection between the fringe cities of the economic zone and the outside is the weakest.3)Xuzhou,as the central city of Huaihai Economic Zone,has a good economic leading role for its surrounding cities but not yet a strong radiation and driving role for the fringe cities,and its driving force as the central city still has great room for improvement.
