Choosing an appropriate GCM (Global Climate Model, GCM) is of great significance for the simulation hydrological cycle over a basin under future climate scenarios. In this study, Rank Score Method (RS) with eight indicators were applied to comprehensively evaluate suitability 19 GCMs issued in Sixth Global Atmosphere and Coupled Model Intercomparison Project (CMIP6) Yellow River Basin (YRB). The results indicated that: 1) perform differently simulating precipitation YRB top six ranking from MRI-ESM2-0, ACCESS-CM2, CNRM-CM6-1, CNRM-ESM2-1, FGOALS-f3-L, MPI-ESM1-2-HR. 2) Most overestimated precipitation, poorly simulated phase distribution extremes mainly due overstimulation wet season span amount season, although all could capture decadal feature annual precipitation. Meanwhile, it also found that most underestimated summer spring 3) well spatial overestimation source area, underestimation northern part middle reaches YRB.
