基于人口集聚度的中国人口集疏格局

Research on the Spatial Pattern of Population Agglomeration and Dispersion in China

人口集聚和疏散是人口空间分布格局最直观和最集中的体现,研究一个地区人口集疏的空间格局,不仅可以揭示该地区人口集疏的内在规律,也有利于深入研究该地区的整体人口分布的态势和规律,更能够体现出区域内经济格局以及城市化格局的发展。基于人口集聚度的中国人口集疏空间格局的研究,有助于准确把握中国人口空间分布的基本脉络,具有一定的学术价值和实践意义。本研究采用了人口集聚度分级评价的方法,依据人口集聚度的不同,将各个地区划分为不同等级的人口集聚区,并对其分别讨论。在此基础上,结合中国人口分布格局、自然条件空间格局、人居环境自然适宜性评价结果以及经济发展格局和城市化格局,对中国的人口集疏的空间格局进行了归纳,得出了中国人口分布"西疏东密"的传统空间格局突出,人口集聚以平原地区为依托并呈现"沿海、沿江、沿线"高度集聚的特征的结论。

Population agglomeration and dispersion are the most direct and the most concentrated expression of population spatial distribution pattern.The research on population agglomeration and dispersion spatial pattern and its formation mechanisms in a specific region will not only help to reveal the population agglomeration and dispersion in the region of the inherent law itself,but also benefit the study of the overall regional population spatial pattern,and even further,the study of regional economy agglomeration and urbanization.With the largest population and significant difference in regional natural condition and economy,China＇s population agglomeration and dispersion,in terms of not only the size but also complexity,are not comparable in the world.Thereby,research on the spatial pattern of China＇s population agglomeration and dispersion,which will contribute to grasping the essence of China＇s population spatial distribution pattern,is of great significance in both academy and practice.The article chose the classification evaluation of population agglomeration,which classified China into many population agglomeration types of different levels according to their population centralization index,and then,discussed them in each type.Based on this and the comprehensive consideration on the spatial distribution pattern of China＇s population,natural conditions,human environment suitability and economic development,the article generalized the spatial pattern of China＇s population agglomeration and dispersion.
