中文摘要：
受到日益加剧的全球变暖趋势的强力驱动,极端降雨及与之相伴的山区流域植被发育斜坡的群发性失稳事件在包括中国在内的多山国家的发生频率越来越高,因此对这一问题的深入研究具有重大的现实意义。到目前为止,降雨—滑坡领域的现有研究成果主要集中在并无成因联系的降雨事件与滑坡事件之间的相互关系及斜坡岩土体水岩相互作用方面,而降雨→滑坡过程链的基础环节———降雨向地下水转化方面的研究成果无论对渗透介质还是渗透过程的刻画精度都还不高。天然斜坡对强降雨的地下水响应大多都是有植物、动物及其生命活动产物共同参与的复杂水文学—水文地质学过程,相关领域的积累还不能覆盖这一过程的核心机理。深入调查山区流域植被发育斜坡对强降雨事件的地下水响应机制不仅可以为斜坡灾害的预报—预警提供更为明晰的理论支撑,而且对于地下水诱发滑坡理论的深化与发展也是重要的。
英文摘要：
Because of the ever-increasing global warming,the frequency of extreme rainfall and regional group slope failure events following the heavy rains in mountainous vegetated areas are getting higher and higher.An in-depth research of this problem is not only of great practical significance to landslide susceptibility assessment,but also of an extensive multidisciplinary theoretical value.The existing research achievements in relative fields mainly focused on the interrelation between rainfall events and landslide events,which are no genetic correlation,as well as the aspect of water-rock interaction in slope rockmass and soilmass.But the basic link of rainfall-landslide process chain — the transformation of rainfall into groundwater has received much less attention whether in permeable medium or in the penetration process.The response of groundwater in natural slopes to heavy rainfall is a complicated hydrologic-hydrogeologic process,which involves plants,animals and their life activities.The existing research accumulation in relevant fields provides realistic basis and certain theory reserves for investigating this problem,but it can not cover the kernel mechanism of the process yet.Probing ＂The response of the groundwater in vegetated slopes in mountainous catchments to heavy rain events＂ could provide slope hazard warning and prediction with a more clearly theoretical support,and it is also important for deepening the theory of landslides caused by groundwater.
