城市扩展迁移轨迹及其驱动因素研究
Research on urban expansion and migration trajectories and their driving factors
摘要
Abstract
Clarifying the trajectories of urban expansion and migration not only provides a tangible record of urban development but also offers decision-making support for urban planning,management,and promoting sustainable urban development,this paper selected 30 cities across the country as case study areas and utilized built-up area data from four time points:1990,2000,2010,and 2020.By analyzing indicators such as urban expansion speed,intensity,dynamic degree,and centroid coordinates,this paper investigated the traj-ectories of urban expansion and migration,and further analyzed the driving factors behind urban expansion.The results showed that from 1990 to 2020,the urban expansion area,speed,intensity,and dynamic degree in the study area had been steadily increasing,with first-tier and quasi-first-tier cities generally expanding faster than second-tier and third-tier cities.The migration directions of the ex-pansion centroided of the 30 cities are quite diversified,with nearly two-thirds of the cities experiencing a southward shift in their ex-pansion centroids.The driving factors of urban expansion were influenced by a combination of natural,human,and other factors.关键词
