摘　　要：基于1996～2010年城市夜间灯光数据,运用城市位序规模法则、空间自相关分析和加权标准差椭圆等分析方法,对长江经济带城市体系空间结构及其变动特征进行系统分析.研究结果表明：长江经济带城市体系总体呈现东部相对密集、中西部相对稀疏的条形核心—边缘结构,1996～ 2010年间,城市体系集中度始终较高且经历了由“数量增长”向“规模扩张”转变的演化过程;城市体系空间增长表现为明显的先扩张后收缩、先向西南方向移动再向东北方向移动、沿海、沿江、沿沪昆线及南北交通通道轴线的动态演进特征;受地理条件、空间距离和发展阶段等因素的影响,长江经济带城市空间分布呈现明显的非连续性和片段化特征,区域内各城市群空间演化特征差异化显著,江浙沪地区已进入都市连绵化阶段,形成较为成熟的跨区域城市群,而长江经济带广大内陆城市群则基本处于以都市郊区化和多中心化为主导的发展阶段,尚不具备形成跨区域城市群的条件,各城市群边界和空间结构也存在诸多不确定性.Based on the DMSP/OLS night time light data of the years 1996 -2010 and using the analytical methods including city rank-size Rule, spatial autocorrelation analysis and the weighted standard deviation ellipse, this thesis systematically analyzes the spatial structure and changing features of the city system in the Yangtze economy belt. According to the research, the city system in the area has a core- peripheral structure, relatively dense in the east and sparse in the middle and the west. Between 1996 and 2010, the density of the city system was constantly high, though changing from increase in number to expansion in scale; The growth in space of the city system also has its obvious features, expanding first and shrinking afterwards, moving southwestward and then northeastward, moving along the coast, the Yangtze River, the Hukun Railway and North-South traffic passages; Due to the geographical conditions, distances and different phases of development, the cities in the Yangtze economy belt lie apparently discontinuously and in fragments. The features of development of each city group in the region are significantly different from each other. The Jiangsu-Zhejiang-Shanghai area has been developing in a continuous pattern, forming a relatively mature interregional city group. However, the vast inland city groups in the Yangtze economy belt are mostly in a city-suburb or multi-center pattern, immature for the forming of interregional city group and also with many uncertainties in the borders and spatial structures of city groups.
