Land use change stands as the primary factor influencing habitat quality (HQ). Clarifying the spatiotemporal change and the obstacle factors of the coupling relationship between HQ and urbanization level (UL) can provide imperative references for achieving sustainability in the Yellow River Basin (YRB). This study is based on the InVEST model, spatial autocorrelation, and obstacle factor analysis to measure the spatiotemporal dynamics and impediments of the coupling relationship between HQ and UL from 2000 to 2020 in the YRB. The findings were as follows: (1) From 2000 to 2020, the HQ showed a tendency of rise first and then fall, with the pattern of "High in the middle and west, low in the east"; (2) from 2000 to 2020, the UL had an upward trend, with the pattern of "Low in the west, high in the middle and east"; (3) the coupling and coordination level of HQ and UL in the YRB changed from extreme incoordination to verge of coordination, and it had a distribution pattern of "High in the east, low in the west", with the high-value area expanding to the east and the low-value area shrinking to the west. (4) Location condition, climate, proportion of construction land, vegetation index, and proportion of non-agricultural employment are the main obstacle factors that determined the coupling and coordination of the HQ and UL.
土地利用变化是影响生境质量（HQ）的主要因素。阐明 HQ 与城市化水平（UL）耦合关系的时空变化及其障碍因素，可以为黄河流域（YRB）实现可持续发展提供重要参考。本研究基于 InVEST 模型、空间自相关和障碍因子分析，测算了 2000-2020 年 YRB 生境质量与城市化水平耦合关系的时空动态及其障碍因素。结果表明：（1）2000-2020 年 HQ 呈先升后降趋势，呈“中高西低”格局；（2）2000-2020 年 UL 呈上升趋势，呈“西低东高”格局；（3）YRB 生境质量与 UL 的耦合协调度由极度失调转变为濒临协调，呈“东高西低”的分布格局，高值区向东扩展，低值区向西收缩；（4）区位条件、气候、建设用地比例、植被指数和非农就业比例是决定 HQ 和 UL 耦合协调的主要障碍因素。
