STUDY ON THE RATIONALITY OF CHINESE POPULATION DISTRBUTION
中国人口分布的合理性研究

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, ara-rble 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.
