本文在人口分布合理性判定标准和指标讨论的基础上,通过对自然环境与人口分布相互关系的定性研究,和综合反映自然条件、经济水平的土地食物生产力与人口分布的定量分析,论证了我国东密西疏人口不均衡分布的内在合理性。

Through qualitative and quantitative analysis of the relationships among natural resources, land productivity and population distribution, the thesis demonstrated the immanent rationality of Chinese population distribution which is dense in the East and sparse in the west of China.Criterions of the rationality of population distribution. The criterion of propulation density is presentative, while that of natural environment and land productivity is basic (or immanent).Natural environment and population distribution. Dividing the inland 29 povinces and municipalities into five groups, it can be seen that land productivity is closely connected with natural environment, and population quantity is adapted to land productivity by comparing the cultivation index, ararble land, multiple-crop index, climate effectiveness index, forest covering index, food output, etc. of the groups.Correlation analysis and food population density. Correlation coefficient between population density and land productivity, and further natural environment. The difference of population distribution is vsry wide measuring by population density, that lowers meauring by arable land population density. Population distribution tends to be rational measuring by food population density.
