The focus of International Strategy for Disaster Reduction has changed from site scale engineering "hard" measures to hose "soft" measures such as regional scale land use planning, that is to say, the most effective way of geological hazard prevention is to restrict land development activity through land use planning. In this paper, the author introduced some international experiences, including legal status of land-use planning and land approval, geological disaster mapping, public-welfare fundamental work of regional planning, and the implementation of restrictions on land development in highly risky area. Specific suggestions on prevention of geological hazard through land use planning are put forward.
