In this paper, the primary scientific issues about the impacts of land use and land cover change (LUCC) on global climate are analyzed, and its research progress is reviewed. LUCC-climate-ecosystem research system integrated with satellite and field observation is constructed, with the consideration of the intercross, integration and interpenetration among subjects to study the land use change effects on global climate. Furthermore, dynamic patterns and mechanisns of LUCC, research approaches about the mechanisms and effectiveness of LUCC impacts on ecosystem and climate, and then the technical routes for the application of integrated satellite-earth research system to land use change effects on global climate are discussed and analyzed.
