【摘要】：本文基于MODIS遙感影像和DMSP/OLS夜間燈光數(shù)據(jù),以及Landsat TM/ETH影像數(shù)據(jù)和統(tǒng)計(jì)年鑒數(shù)據(jù),通過計(jì)算標(biāo)準(zhǔn)城市用地復(fù)合指數(shù)NUACI,提取2000、2005和2010年三個(gè)節(jié)點(diǎn)年份長江中游城市群城市建成區(qū)范圍,分析長江中游環(huán)鄂陽湖城市群、武漢城市圈和環(huán)長株潭城市群城市建成區(qū)空間分布和演變特征。從總體來看,2000—2010年之間長江中游城市群的城市建成區(qū)面積擴(kuò)展速度不斷加快,其中武漢城市圈城市建成區(qū)面積空間分布最廣且城市建成區(qū)分布單中心圈層空間格局顯著,但隨著擴(kuò)散效應(yīng)的加強(qiáng),逐步形成以"鄂州—黃石—黃岡"三城市為核心的城市圈副中心:環(huán)長株潭城市群由單城市星狀空間分布向多中心網(wǎng)絡(luò)狀空間分布格局發(fā)展,"長沙—株洲—湘潭"三城市集群發(fā)展更為顯著;環(huán)鄱陽湖城市群城市建成區(qū)空間擴(kuò)展速度最快,空間分布格局放射軸向特征顯著,城市建成區(qū)的空間擴(kuò)展與交通要素關(guān)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.
