宁夏人口分布区域差异研究

Regional differences of population distribution in Ningxia

为了解近30 a宁夏人口分布的区域差异,运用Arcview,Excel等软件,通过人口自然密度和综合经济密度的定性与定量相结合以及罗伦斯曲线等方法,研究了宁夏人口在1980—2008年期间的时序和空间分布变化.结果表明,各地区人口分布变化速度在加快,人口趋于向中部和北部社会经济发展水平高的县市集中,政府的移民政策对人口分布的影响作用较强,人口分布的历史基础对人口分布的影响在逐渐减小;南部山区人口呈负增长,中部干旱带人口稀疏,北部川区和南部山区人口密集,分布不平衡.

In order to explore Ningxia population distribution from 1980-2008,the development of Ningxia population and spatial distribution in each city and county regions have been researched by using natural population density,comprehensive economic density and florence curve in qualitative and quantitative methods.The conclusion shown that the populations of all regions changes rapidly,and it tends to the cities where has high social and economic development level in the north and central of Ningxia.Government’s immigration policy plays important role of population distribution,and the historical population basis distribution has less effect on the population distribution.Population growth of southern mountain region is negative;There is sparsely population in the central arid,densely population in southern mountainous area and northern river areas,the distribution is uneven.
