摘      要：Global land cover maps are important sources of information for a wide range of studies including land change analysis and climate change *** the global land cover maps attempt to present a consistent and homogenous data in terms of the production process,the existing datasets offer coarse resolution data,e.g.1000 m for IGBP DISCover and 300 m for GlobeCover 2009 that is oftentimes ***,GlobeLand30 data based on Landsat archive for two timestamps of 2000 and 2010 has been *** presents a finer spatial resolution of 30 m,which provides numerous opportunities for a wide range of *** main objective of this study is to use this dataset for characterizing global land cover patterns,monitoring,and identifying extreme land change cases with their types and *** findings reveal massive land change patterns including deforestation,desertification,shrinkage of water bodies,and urbanization across the *** results and discussions of this research can help policy-makers,environmental planners,ecosystem services providers and climate change researchers to gain finer insights about the forms of global land *** research calls for further investigation of the underlying causes of the massive changes and their consequences on our ecosystems and human populations.
