Abstract: A review of the geomorphoiogical thoughts in the last one hundred years indicates that modern geomorphology has inherited the rational parts of W.M. Davis'theories and, on the other hand, has experienced a revolution in theory framework. Davis proposed his theory framework of Geomorp-hology, i. e., the interpretative description of landforms by structure, process and time, and developed and perfected his theory of erosion cycles in the viewpoint of geomorphic evolution.His evolution viewpoint and his research method of comining deduction with observation hitherto have their realistic significance, Thanks to the impetus by systems theory and oceanic research, a scientific revolution in Geomorphology took place after Davis during late 1940s to early 1960s.Its hallmarks are,(a)the theoretical core of geomorphology has been transferred as a whole from the trinity of structure-process-time to that of morphology-process-timespace;and (b)the old concepta in Davis have been engiven new meaningss, and the study area of geomorphology has been greatly larged.
