摘要
青海省地形多样,分带性显著。北依祁连山,西为柴达木盆地,东跨黄土高原,南为青南高原,地质灾害种类繁多,广泛分布。文章通过青海省671个滑坡进行分类,举例说明各种滑坡类型的特点及其危害,根据省内滑坡地质灾害的类型与发育特征,对滑坡成灾环境、发育特点进行归纳、总结,并对青海省滑坡地质灾害的发展趋势进行预测分析,加强地质灾害的研究,深化对地质灾害的认识,有利于构筑防灾体系,促使人类避免群死群伤事件,将地质灾害防治从分散的、被动应急状况,转变为有组织的、主动的和有预见性的局面。
Landform is various in Qinghai province with notable zoning. The north leans on Qilian Mountain,the west is Qaidam Basin,the east strides over a loess plateau,and the south is Qinghai south highland with various and broad distribution geological disasters. This article carried out landslide types on the basis of 671 landslides in Qinghai to illustrate different kinds of landslide types' characteristic and their hazards. According to the type of landslide and developmental characteristics,to summarize and conclude landslide hazard environment and development characteristics,to predict and analyze to the development trend of the landslide,to strengthen the study of geological disasters,and to deepen the understanding of geological disasters in favour of building disaster prevention system,prompting human to avoid geological hazards,and changing scattered and passive emergency into organized,active and predictive situation.
