Land use conflict, as the spatial manifestation of conflicting human-land relationship, has a profound impact on sustainable use of regional land resources. Taking the Yellow River Basin (YRB) as an example, a land use conflict assessment model was constructed based on landscape pattern indices. The dynamic patterns and driving factors of land use conflict in the YRB and the corresponding driving factors were then assessed from 2000 to 2020 based on spatial autocorrelation analysis and the geodetector method. Significant spatial and temporal differences in land use conflict were observed in the YRB from 2000 to 2020. During this period, the area of stable controllable decreased by 3465 km, whereas the areas of strong and extreme conflict increased by 34,964 and 13,057 km, respectively. The expansion of areas with extreme and strong conflict mostly occurred in regions with high urbanization and human activity, including northern Shaanxi, Hetao Plain, and the Yellow River Delta. The distribution of land use conflict in the YRB from 2000 to 2020 was characterized by significant spatial agglomeration; high-value cluster conflict mainly extended from the midstream area to the upstream area, whereas low-value clusters tended to be concentrated in the upstream area of the Qinghai and Qilian Mountains. The spatial and temporal differentiation in land use conflict from 2000 to 2020 was influenced by factors related to the natural environment, geographic location, social economy, and regional policy in the YRB. The effects of elevation, distance to the nearest major river, population, economic density, and per capita disposable income of residents increased continuously during the study period, whereas the influences of mean annual precipitation and ecological retreat weakened. Analysis of the interactions between driving factors showed significant dual-factor and non-liner enhancement effects on the spatial and temporal differentiation in land use conflict. The findings provide a scientific reference for the comprehensive management of national land and ecological construction in the YRB.
土地利用冲突是人类-土地关系冲突的空间表现，对区域土地资源的可持续利用具有深远影响。以黄河流域（YRB）为例，构建了基于景观格局指数的土地利用冲突评估模型。然后，基于空间自相关分析和地理探测器方法，评估了 2000 年至 2020 年 YRB 土地利用冲突的动态格局和驱动因素及其相应的驱动因素。2000 年至 2020 年，YRB 的土地利用冲突存在显著的时空差异。在此期间，稳定可控面积减少了 3465 平方公里，而强冲突和极端冲突面积分别增加了 34964 平方公里和 13057 平方公里。极端冲突和强冲突面积的扩大主要发生在城市化和人类活动水平较高的地区，包括陕北、河套平原和黄河三角洲。2000 年至 2020 年，YRB 的土地利用冲突分布特征为显著的空间集聚；高值聚类冲突主要从中游地区向上游地区扩展，而低值聚类则倾向于集中在青海南部和祁连山地区。2000 年至 2020 年土地利用冲突的时空分异受到 YRB 自然环境、地理位置、社会经济和区域政策等因素的影响。海拔、距最近大河的距离、人口、经济密度和居民人均可支配收入等因素的影响在研究期间持续增加，而年平均降水量和生态退缩的影响则减弱。驱动因素相互作用分析表明，双因素和非线性增强效应对土地利用冲突的时空分异具有显著影响。研究结果为黄河流域乃至全国土地综合管理和生态建设提供了科学参考。
