On the basis of geo dynamics and lithosphere dynamics, in this paper it is discussed that the neotectonic movement was induced by intensive rising of the Qinghai\|Tibet Plateau, and the pattern of regional geologic structures, stratum and lithology, topography and physiognomy in the northeastern Qinghai\|Tibet Plateau were resulted from Neotectonic movements. Scales and characteristics of these geological units were also controlled by Neotectonic movements. Neotectonic movement and its effects control the evolution of geological environment and the development of geological hazards directly or indirectly. Geological hazards in this region express characteristics of seriousness, frequentativeness, zonation, cyclycity, group\|occarence and association.
