【摘要】：基于DMSP/OLS夜间灯光指数和SPOT-VEGETATION逐旬NDVI数据构建人居指数,模拟武汉市2000,2012年人口空间分布。采用空间自相关模型,从时空角度分析2000—2012年武汉市人口的空间分布格局及演变规律。结果表明:1利用夜间灯光强度估算方法可快速准确模拟武汉市人口空间分布。2人口空间分布格局有向武汉市中心城区集聚的趋势,具有"中间高周围低"的特征。3武汉市人口空间分布表现出较强的空间自相关性,根据局部自相关分析,"高-高"类型区主要分布在武昌、xZ口、江汉、江岸等中心区,"低-高"类型区主要出现在江河流域附近;随着时间的推移人口分布的"高-高"类型区扩大,表明武汉市人口在向中心城区聚集的过程中远城区也形成了相应的人口集聚中心。
[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.
