基于异速生长模型的我国城市人地关系动态研究

文章利用2010—2016年中国293个地级及以上城市城区人口和建成区面积数据，结合生物学的异速生长模型，对中国城市人口迁移的空间异质性特征及规律进行分析，深入挖掘异速生长关系下中国人口增长与土地扩张的动态过程及内在演化动力。研究发现:中国人口集聚空间非均衡性特点鲜明，东部经济发达地区人口集聚能力强，西部经济落后地区人口集聚能力弱，东西人口集聚现象对比鲜明，西部是东部人口迁移主要来源地。资源型城市在产业调整及资源枯竭时期，人口外流现象严重，此时资源型城市人口增长速度减缓，或出现负增长现象。

Dynamic study of urban man land relationship in China based on allometric growth model

Based on the data of urban population and built-up area of 293 cities at prefecture level and above in China from 2010 to 2016, combined with the biological allometric growth model, this paper analyzes the spatial heterogeneity characteristics and regular patterns of urban population migration in China, and deeply explores the dynamic process and internal evolution dynamics of population growth and land expansion in China under the allometric growth relationship. The results show that: the unbalanced characteristics of China's population agglomeration space are distinct, with strong population agglomeration capacity in economically developed areas in the east and weak population agglomeration capacity in economically backward areas in the west. There is a sharp contrast between the east and the west, and the west is the main source of population migration to the east. During the period of industrial adjustment and resource depletion, the phenomenon of population outflow is serious in resource-based cities. At this time, the growth rate of population in resource-based cities slows down or negative growth occurs.
