1993—2010年山东省人口分布的空间演变特征分析

CHARACTERISTIC STUDY ON SPATIAL EVOLUTION OF POPULATION DISTRIBUTION IN SHANDONG PROVINCE DURING THE PERIOD OF 1993 -2010

将人口分布的传统分析方法和空间自相关模型相结合，借助GIS技术对20世纪90年代以来山东省人口分布的空间格局及其演变特征进行分析，研究结果表明：1）2010年山东省17个地级市之间人口数量差异明显；人口密度在地级市之间和不同县级行政单元之间都存在较大差异；人口空间分布具有较强的空间自相关性．2）20世纪90年代以来山东省各地市人口总量和人口密度的增长都十分明显；全省人口空间分布较均衡，但呈现出不断集中趋势；人口分布趋同趋势先减小后增强等演变特征．

By using the traditional method of the population distribution and spatial auto - correlation analysis model, the spatio - temporal dynamics of population distribution of Shandong province have been analyzed based on GIS technology since the 1990s. The results show that the population quantity and its density of counties is quite different in 2010,and the population distribution has a stronger spatial autocorrelation. Since the 1990s, the total population and population density have grown obviously. The province＇s population but it presents a constant concentration trend, and the population centralization strengthen. spatial distribution is balanced, is to weaken first and then to
