Abstract

The problem of unbalanced development has become increasingly prominent in the northern and southern regions,and the phenomenon of the North-South spatial differentiation of China's population has aroused widespread concern. Based on the population census data from 1982 to 2020,this paper explores the spatial differentiation pattern of the population and its influencing factors in the southeastern half of HU Huanyong Line by the means of Theil index and geographical detector. The results show that: 1) It presents stable population distribution pattern which is denser in the south than in the north in the southeastern half of HU Huanyong Line,and it still maintains the advantages of population size and density in the southern region from 1982 to 2020. 2) The overall difference of population distribution continues to widen in the study area,which is dominated by the intra-regional differences between the northern region and the southern region in the southeastern half of HU Huanyong Line. Among them,the internal disparity in the southern region is smaller than that in the northern region,but the increase range is greater. 3) The migration direction of population shifts to the south in the study area,and the regional differences of population density change continue to expand. A few regions present the characteristic of rapid population growth with the significant advantage of population density. 4) The spatial differentiation of population is the result of the combined effect of natural environment,economic and social factors. Economic and social factors,such as the economic development level,innovation ability and employment opportunities,are the main factors of population density change,among which the innovation ability is playing a greater role in the population density.

Key words： population distribution; northern and southern regions; Qinling-Huaihe Line; HU Huanyong Line; natural environment; economic development level; innovation ability
