摘要
运用岩石圈动力学和大陆动力学理论 ,讨论了青藏高原隆升使青藏高原东北部地区产生的新构造运动效应 ,认为本区的区域地质构造格局、地层岩性和地形地貌均是新构造运动的产物 ,其发育规模和特征均严格受新构造运动控制 。
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.
