【摘要】：对全球气候变化对地质灾害的响应关系,尤其是对滑坡和泥石流灾害的响应关系进行了综述。工业化革命以来,特别是近几十年来全球气候发生着重要的变化,全球几乎所有地区都经历着升温过程。全球气候变化对极端天气事件(极端降雨、气温升高、强风和洪水灾害)的影响尤为强烈,并且增加了地质灾害的发生风险。其中,水循环和气温的变化是影响地质灾害发生的直接因素。气温上升会导致大气层含水量升高、冰川冻土退化、海平面上升、蒸发作用增强;水循环变化会导致降雨频率、降水周期、降水强度的改变。日益增加的极端天气与同岩土体相互作用,导致了不同类型地质灾害的发生,严重威胁着人类的生活起居。
[Abstract]:The response relationship of global climate change to geological hazards, especially to landslide and debris flow disasters, is reviewed in this paper. Since the industrial revolution, especially in recent decades, the global climate has undergone important changes, almost all regions of the world are experiencing a warming process. Global climate change has a particularly strong impact on extreme weather events (extreme rainfall, rising temperatures, strong winds and floods) and increases the risk of geological hazards. Among them, the change of water cycle and temperature is the direct factor that affects the occurrence of geological disaster. The rise of temperature will lead to the increase of atmospheric water content, the degradation of glacial permafrost, the rise of sea level and the enhancement of evaporation, and the change of water cycle will lead to the change of rainfall frequency, precipitation cycle and precipitation intensity. The increasing interaction between extreme weather and the same rock and soil resulted in the occurrence of different types of geological disasters, which seriously threatened the daily life of human beings.
