In light of characteristics of subsidence area due to coal mining,the land use informatic Tupu of the subsidence area is studied according to the theories of geo-informatic Tupu.In view of the particularity of land use,the research method of land use informatic Tupu is put forward.Taking a certain subsidence area in Shandong Province of China as the research project,the changes of land use informatic Tupu of subsidence area before and after coal mining is analyzed.Taking a reclamation area in Xuzhou city as case,the changes of its land use informatic Tupu before and after reclaiming is studied.The results of research proved that the informatic Tupu is an effective tool for the study of the land use change in subsidence area.
