How to realize the sustainable use of land resources is extremely important for environmental protection and sustainable development in ecologically fragile regions. Nevertheless, the logic of achieving sustainable land use (SLU) in ecologically fragile regions and the corrective mechanisms for the implementation of land use efficiency systems are not fully revealed in theory. The Yellow River Basin is an important ecological barrier in China, and it holds an important position in China’s economic and social development, as well as for ecological safety. However, the basin is also ecologically vulnerable. Therefore, investigating eight central cities in the Yellow River Basin of China and using municipal-level panel data from 2009 to 2018, this paper constructs a multidimensional index system and is dedicated to carrying out a comprehensive evaluation of SLU and the diagnosis of obstacle factors in ecologically fragile regions. The study found the following: (1) From 2009 to 2018, the SLU level in the central cities of the Yellow River Basin evolved from the “Unsustainable Level” to the “Initial Sustainable Level” and then to the “Basic Sustainable Level”. The overall development trend was positive, and the level of SLU also rose. (2) From 2009 to 2018, there was significant geographical variation in spatial disparities in SLU in the central cities of the Yellow River Basin. In 2018, the average comprehensive score of SLU showed a pattern of downstream > upstream > midstream. (3) The obstacle factors of SLU in the Yellow River Basin of these cities in 2009 were concentrated on resource and environmental sustainability, while those in 2018 were concentrated on social acceptability. (4) In terms of the transfer process of land use types in these Yellow River Basin cities, the transfer from cultivated land to other types of land use played a major role, while construction land showed a significant expansion over the past ten years.
如何实现土地资源的可持续利用对生态脆弱地区的环境保护和可持续发展极为重要。然而，生态脆弱地区实现可持续土地利用（SLU）的逻辑以及土地利用效率系统实施的矫正机制在理论上尚未得到充分揭示。黄河流域是中国重要的生态屏障，在中国经济社会发展以及生态安全方面具有重要地位。然而，该流域生态也较为脆弱。因此，本文以中国黄河流域的八个中心城市为研究对象，利用2009年至2018年的市级面板数据，构建多维指标体系，致力于对生态脆弱地区的可持续土地利用进行综合评价及障碍因素诊断。研究发现如下：（1）2009年至2018年，黄河流域中心城市的可持续土地利用水平从“不可持续水平”演变为“初步可持续水平”，进而发展为“基本可持续水平”。总体发展趋势向好，可持续土地利用水平也有所提升。（2）2009年至2018年，黄河流域中心城市可持续土地利用的空间差异存在显著的地理特征。2018年，可持续土地利用平均综合得分呈现下游>上游>中游的格局。（3）2009年这些城市黄河流域可持续土地利用的障碍因素集中在资源与环境可持续性方面，而2018年则集中在社会可接受性方面。（4）在这些黄河流域城市土地利用类型的转移过程中，耕地向其他土地利用类型的转移起主要作用，而建设用地在过去十年呈现出显著扩张。
