摘要

The Qinghai-Tibet Plateau (QTP) is the most unique region of human-land relations,and its main factor is population.By building a population and space dataset of the QTP at the township level from 1982 to 2017,this paper presents the pattern evolvement and regional distribution characteristics of township-level population in the QTP in detail for the first time.By using Geodetector meth-od to analyze the influencing factors of township-level population change in the QTP,this paper provides scientific foundations for studying the Third Pole,ecological environment protection of the QTP,and human-land relations.The conclusions are as follows:1) The population spatial distribution is not balanced at the township level,presents the regional differentiation characteristics of 'dense in southeast and sparse in northwest'along the 'Qilian-Jilong Line',and demonstrates the phenomenon of population center of gravity moving to the hinterland of the plateau at an accelerated speed;2) The township-level population develops in a decentralized trend in general,and the cold-and hot-spot distribution of population has prominent spatial distribution characteristics.The population hot spots are concentrated in the surrounding areas of Xining,Golmud,Hotan and Lijiang;3) The population of the QTP is increasing,and the inter-annual change of township population has a relatively stable regional regularity;4) The level of per capita income is the leading factor in the change of township population,and its effect intensity is increasing continuously.The relative effect intensity of urbaniza-tion level and location conditions on population change has decreased significantly after 2000.The adaptability of living environment,such as topography and climate,has little influence on population change.
