【摘要】：基于DMSP/OLS夜間燈光指數(shù)和SPOT-VEGETATION逐旬NDVI數(shù)據(jù)構(gòu)建人居指數(shù),模擬武漢市2000,2012年人口空間分布。采用空間自相關(guān)模型,從時(shí)空角度分析2000—2012年武漢市人口的空間分布格局及演變規(guī)律。結(jié)果表明:1利用夜間燈光強(qiáng)度估算方法可快速準(zhǔn)確模擬武漢市人口空間分布。2人口空間分布格局有向武漢市中心城區(qū)集聚的趨勢(shì),具有"中間高周圍低"的特征。3武漢市人口空間分布表現(xiàn)出較強(qiáng)的空間自相關(guān)性,根據(jù)局部自相關(guān)分析,"高-高"類型區(qū)主要分布在武昌、xZ口、江漢、江岸等中心區(qū),"低-高"類型區(qū)主要出現(xiàn)在江河流域附近;隨著時(shí)間的推移人口分布的"高-高"類型區(qū)擴(kuò)大,表明武漢市人口在向中心城區(qū)聚集的過(guò)程中遠(yuǎn)城區(qū)也形成了相應(yīng)的人口集聚中心。
[Abstract]:Based on the DMSP/OLS night light index and SPOT-VEGETATION NDVI data, the residential index was constructed to simulate the spatial distribution of population in Wuhan in 2000 and 2012. By using spatial autocorrelation model, the spatial distribution pattern and evolution law of Wuhan population from 2000 to 2012 are analyzed from the point of view of time and space. The results show that: (1) the spatial distribution of population in Wuhan can be simulated quickly and accurately by using the method of estimating the intensity of light at night. (2) the spatial distribution pattern of population has the tendency of agglomeration to the city center of Wuhan. The spatial distribution of population in Wuhan shows strong spatial autocorrelation. According to the local autocorrelation analysis, the "high-high" type areas are mainly distributed in the central areas of Wuchang, xZ mouth, Jianghan, Jiangan, etc. The "low-high" type area mainly appears near the river basin; With the passage of time, the expansion of the "high-high" type of population distribution shows that the population of Wuhan has also formed the corresponding population concentration center in the process of gathering into the central urban area.
