白龙江流域地貌演化及其对地质灾害的影响
Geomorphology evolution of Bailong River Basin and its impact on Geo-hazard
摘要
Abstract
The Bailong River Basin is located in the transition zone of China from the first step to the second step, which is one of the areas suffered the most from the geological disasters in China. In recent years, the research has shown that the influence of Qinghai-Tibet plateau uplift on the Bailong River Basin geomorphology evolution is significant. The characteristics of geomor-phology evolution of Bailong River Basin is cascade and differential uplifts;the planation surface, multilayer cave system and the development of river terraces is the direct response to the plateau uplift. The temporal coupling of geomorphic evolution, rainfall and earthquake formed the present disaster chain pattern of Bailongjang earthquake-collapse, slide-debris. The plateau uplift effect is the essential cause for the development of geological disasters. With the further uplift of mountain, the dynamic condi-tions of the geological disaster development will be more sufficient, which will be in a high incidence trend in a certain period, it is a rebalancing process to the geomorphic evolution power.关键词
