【摘要】：本文基于MODIS遥感影像和DMSP/OLS夜间灯光数据,以及Landsat TM/ETH影像数据和统计年鉴数据,通过计算标准城市用地复合指数NUACI,提取2000、2005和2010年三个节点年份长江中游城市群城市建成区范围,分析长江中游环鄂阳湖城市群、武汉城市圈和环长株潭城市群城市建成区空间分布和演变特征。从总体来看,2000—2010年之间长江中游城市群的城市建成区面积扩展速度不断加快,其中武汉城市圈城市建成区面积空间分布最广且城市建成区分布单中心圈层空间格局显著,但随着扩散效应的加强,逐步形成以"鄂州—黄石—黄冈"三城市为核心的城市圈副中心:环长株潭城市群由单城市星状空间分布向多中心网络状空间分布格局发展,"长沙—株洲—湘潭"三城市集群发展更为显著;环鄱阳湖城市群城市建成区空间扩展速度最快,空间分布格局放射轴向特征显著,城市建成区的空间扩展与交通要素关系密切。
[Abstract]:In this paper, MODIS remote sensing image and DMSP/OLS night light data based on Landsat and TM/ETH image data and statistical yearbook data, calculated by the standard of city land composite index NUACI, extract 2000, 2005 and 2010 three node year City Yangtze River city group of built-up area, analysis of the middle reaches of the Yangtze River City group, Hubei ring Yang Lake of Wuhan city circle and ring of Chang Zhu Tan city cluster City built-up area spatial distribution and evolution characteristics. Overall, the Yangtze River city group city between 2000 and 2010 the built-up area expansion is speeding up, the Wuhan city circle city built area spatial distribution and the most widely distributed single center circle city spatial pattern is significant, but with the strengthening of the diffusion effect, gradually formed a "Ezhou - Huangshi - Huanggang" three city is the core of the city circle center: ring of Changsha Zhuzhou Xiangtan city group is composed of a single star city spatial distribution network to the spatial distribution pattern of the development of multi center, "the development of Changsha - Zhuzhou - Xiangtan" three city clusters are more significant; the fastest expansion of built-up area of Poyang Lake city group city space, spatial distribution pattern the axial radiation characteristics and close relationship between city spatial expansion and traffic elements built area.
