摘　　要：黄河流域是中国重要的生态屏障,研究其水源涵养服务功能对推动黄河流域生态保护与高质量发展具有重大意义。采用InVEST模型量化黄河流域1980—2020年水源涵养服务功能,使用空间自相关分析黄河流域水源涵养服务功能空间分布模式,并运用地理探测器分析黄河流域水源涵养服务功能的驱动因素。结果表明:(1)1980—2020年黄河流域水源涵养量为174.8639亿m^(3)—378.4538亿m^(3),多年平均水源涵养量265.0475亿m^(3),其中草地与林地多年平均水源涵养量分别占黄河全流域水源涵养总量的52.94%和24.27%。全流域水源涵养量呈现上下游地区较高,中游地区较低的分布格局。(2)全局莫兰指数为0.875,表明黄河流域水源涵养服务在空间上呈现聚集分布,以低-低聚集与高-高聚集为主。(3)1980—2020年不同地类平均水源涵养能力排序:灌木林>有林地>高覆盖草地>其他林地>中覆盖草地>低覆盖草地>旱地>建设用地>未利用地>水田>水域。(4)降水量是影响黄河流域水源涵养量变化的主要驱动因子,降水量与土地利用间交互作用对黄河流域水源涵养服务功能空间分异解释力显著增强。研究结果可为黄河流域生态系统管理与高质量发展提供重要参考。The Yellow River Basin is an important ecological barrier in China.With the increasing interference of human activities,the ecological problems of the Yellow River Basin have received more attention from the academic community.On April 1,2023,the Yellow River Protection Law of the People′s Republic of China was formally implemented,which explicitly required to strengthen the synergistic management of the Yellow River′s water resources,water environment,and water ecology in order to realize the harmony between human and nature.It is of great significance to study water conservation service function to promote ecological protection and high⁃quality development in the Yellow River Basin.Based on the InVEST model,this study quantitatively evaluated the water conservation service function of the Yellow River Basin from 1980 to 2020.We analyzed the spatial distribution pattern of the water conservation service function by the spatial autocorrelation and analyzed the factors affecting change of the water conservation service function via geographical detector.The results showed that:(1)the water conservation volume of the Yellow River Basin from 1980 to 2020 ranged from 17486.39 million m^(3) to 37845.38 million m^(3),with the averagely annual water conservation volume of 26504.75 million m^(3).The multi⁃year average water conservation volume of the grassland and forestland accounted for 52.94%and 24.27%of the total water conservation volume in the Yellow River Basin,respectively.A higher distribution pattern in the upstream and downstream regions and a lower distribution pattern in the middle reaches were presented.(2)The global Moran index was 0.875,indicating that the spatial distribution of water conservation service in the Yellow River Basin showed aggregation distribution,which was dominated by low⁃low aggregation and high⁃high aggregation.(3)From 1980 to 2020,the order of average water conservation amount of different land types was shrubbery>forest land>high cover grassland>other forest land>medium c
