Kunming Vocational and Technical Colege of Industry,Kunming,Yunnan Province,65o3O2 China Abstract: Using GlobeLand3O surface cover data from Xundian County，Yunnan Province in 2Ooo and 2020 as data sources,this study procesed the data with ArcGIS1O.6 for cropping and overlay analysis,and other processing toanalyze theamplitude,dynamics,and land transfer of land usechanges.The spatiotemporal changes in surface cover of Xundian County over the past 2O years were studied.The results indicate that:Firstly,the overalltrend of landcoverchangeinXundian Countybetween2OoOand2O2Owasanincreaseingrassand,waterbodies,andartificialsurfaces,whiletheareaofcutivatedland,forestland,andshrublanddecreased;Secondly,theartificialland cover types in Xundian County have the most drastic changes,with a dynamic degree K of 29.97% for a single land use type; Thirdly,the dynamic degree Lc of comprehensive land use in Xundian County was 0.19% .Forthly,the transferand changeoflanduse types mainly involve themutual transferofcultivated land,grassand,artificial surfaces,and forest land.
