【Abstract】 In view of the definition of disaster chain, this paper postulates the definition of disaster geomorphologic chain, a disaster chain made of series of geomorphologic disasters The disaster geomorphologic chain can be divided into different types on the basis of the different criteria Two kinds of thresholds in geomorphic disasters are analyzed according to Schumm’s geomorphic theory Finally, the critical process in the disaster geomorphologic chain is discussed by using the theory of dissipation theory更多还原
