Comparative Study About The Centralization And Discretization Of The Population Distribution During The Urbanization In China And The USA

Urbanization development and regional population distribution research are hot topics in the field of population geography research.There are also different characteristics of population distribution changes in different stages of urbanization.This study defines the process of population distribution change as two processes of centralization and discretization and discretization of population distribution,reflecting the process of continuous accumulation and differentiation of population distribution and the process of tending to decentralization and equalization,with population density standard deviation and centralization level.The degree of discrimination is used to determine the process characteristics of population distribution,and the authenticity of population distribution centralization and discretization is verified through the analysis and comparison of the population data of China and the United States.When the urbanization is in the early stage,the level is low,and the development speed is fast,it usually corresponds to the centralization stage of population distribution.When the urbanization is in the later stage and the level is high,the discretization of population distribution may occur.This may be the structural adjustment of the population distribution.After experiencing the rapid development of urbanization,great changes have taken place in the industries,space,and resources related to population development.The adjustment of population distribution is a relatively slow process.The results of this adjustment and change may be gradually revealed in the later stages of urbanization.With the continued advancement of high-level urbanization,the population distribution may return to a centralization process.Currently,China is in the middle period of urbanization.The level of urbanization is continuously rising,the development speed is still rapid,and the population distribution is in a centralization stage.There are large differences in the population distribution in the region.The research and analysis of urbanization process and the centralization and discretization of population distribution will help us better judge the current situation of population distribution changes in the region,and provide a direction for thinking on how to optimize the distribution of urbanization and promote the balanced development of regional population distribution..
