摘要: 准确地识别城市化进程中建设用地的变化情况及其背后的驱动力,对城市后续的可持续发展具有重要意义。本文首先以2000—2020年遥感影像为基础,对太原市建设用地空间分布变化进行研究,然后结合地理探测器模型和地理加权回归模型,对研究区建设用地的空间分布影响驱动力因子进行研究,得到以下结论:除政策因素外,现有的城市建设用地空间分布变化还受到高程、交通、GDP、人口等因素的显著作用。太原市城市建设用地变化的布局不单是GDP变化、人口变化、海拔高度、公路网密度4个显著性因子均匀、独立、直接作用的结果,而是具有空间异质性的各因子两两交互作用后增效的产物。本文成果有望为城市建设用地驱动力研究提供一种新思路。

Abstract: Accurate identification of the change of construction land in the process of urbanization and the driving force behind it is of great significance to the subsequent sustainable development of cities. Based on remote sensing images from 2000 to 2020, this study studied the spatial distribution changes of construction land in Taiyuan city, and then combined the geographic detector model and the geographically weighted regression model to study the driving factors influencing the spatial distribution of construction land in the study area, and the following conclusions were reached:In addition to the policy factors, the existing urban construction land spatial distribution changes are also affected by elevation, traffic, GDP, population and other factors. The distribution of urban construction land change in Taiyuan is not only the result of the uniform, independent and direct effects of the four significant factors, such as GDP change, population change, altitude change and highway network density, but the product of the synergistic effects of the pairwise interaction of various factors with spatial heterogeneity. The results of this study are expected to provide a new way to study the driving forces of urban construction land.
