Abstract：【Objection/Meaning】The studyaimed to explore the temporal and spatial evolution laws of non-grain conversionof farmlandattheplotscaleintheeconomicalldevelopedareasanditsinfluencing factors，soastoprovidereference forthe formulation offrmland protection policies.【Methods/Procedures】Firstlybased onthe interpretationofremote sensing images， thetypesanddegresofnon-grainconversionoffarmlandinHangzhouCityin2O10，2015and220wereidentifiedattheplot scale.Furthermore，，withthehelpoftheGeographicallyand Temporally WeightedRegression model （GTWR），theinfluencing mechanismof nongrain conversionoffarmland was explored.【Results/Conclusions】The studyfound that： （1）From 2010 to 2015，thenon-grainconversion rateof farmland in Hangzhou City increased from 26.05% to 31.42% ，and thendecreased to 15.83% from2015 to2O2o.Thespatialdistributionimbalanceintensified.（2）Duringtheresearchperiod，theareaofpondaquaculture decreasedsignificantlyhilethareaofegetableproductionontiuedtoincrease.（3）Theorigialqualityoffmlandagaated theexpansionofnon-grainconversionoffamland.Onthecontrary，thegeograpicalconditions werethekeyfactorstoiibitthe spreadofthis trend.Theimpactoftheacesibilityofagriculturallandscapesonthenon-grainconversionoffarmlandchanged from negative topositive.（4）The influencing factorsof non-grainconversionoffarmland mainlyplayedarole intheurban fringe areas， andthespatialheterogeneitywas high.Basedontheaboveconclusions，theatentionshouldbepaidtothetemporalandspatial evolutionandthetypetrendsofnon-grainconversionoffarmland，thediferencesinfactorssuchastheoriginalqualityand geographicalconditionssouldbeconsidered，andthemanagementandcontrolofurban fringe areasshouldbetrengtheed，oas
