Abstract：Taking Inner MongoliaAutonomousRegionasthestudyarea，fiveinterpolationmethods，namelythe Inverse DistanceWeighted（IDW），Spline，OrdinaryKriging（OK），LocalPolynomialInterpolation（LPI），andRadialBasisFunction（BF） methods，wereemployedtospatiallyinterpolaterainfalldatafrom89meteorologicalstationswithinthestudyareaandits suroundings.Subsequentlyacrosvalidationaproachwasadoptedtocomparethepredictionauracyofthefiveinterpolation methods，therebyselectingthemostsuitableinterpolationmethodforInerMongoliaAutonomousRegion.Theresearchrevealed thattheLocalPolynomialInterpolationexhbitedthehghestinterpolationaccuracyptiallyeflectingthespatiallcontiuous variationcharacteristicsofrainfallwithintheregion.Conversely，theOrdinaryKrigingmethoddemonstratedthelowest interpolationauracy，withsimulationresultstendingtoproducethe"Bul's-Eye"efet.Theresearchfindingscanprovide relevantguidanceforselectingrainfallinterpolationmodelsthatcapturethespatio-temporaldistributionofrainfallinIner Mongolia and offer insights for related studies.
