发布时间：2018-11-25 19:25
【摘要】：以淮河流域为研究区域,以县域为研究单元,选取人口数及人口密度为研究指标,通过20世纪80年代以来淮河流域人口密度、不均衡指数、重心移动、偏移-分享分析及空间自相关分析等来研究人口空间格局及其演变趋势.结果表明:淮河流域人口增长速度在变慢,人口密度仍在全国平均人口密度的4倍以上,人口分布存在一定的空间关联性,在淮河各支流的中、上游县市区域形成人口集聚区域,人口呈不均衡分布状态且不均衡趋势加强,人口重心逐渐向东北方向迁移.
[Abstract]:Taking the Huaihe River Basin as the research area, taking the county area as the research unit and selecting the population number and population density as the research index, the population density, the unbalanced index and the center of gravity of the Huaihe River Basin since the 1980s have been shifted. Migration-sharing analysis and spatial autocorrelation analysis are used to study population spatial pattern and its evolution trend. The results show that the population growth rate in the Huaihe River Basin is becoming slower, the population density is still more than 4 times of the national average population density, and the population distribution has a certain spatial correlation, in the Huaihe River tributaries, The population concentration area is formed in the upstream counties and cities, the population distribution is unbalanced and the unbalanced trend is strengthened, and the population center of gravity is gradually moving to the northeast.
