摘　　要：通过引入灾害链理论对斜坡地质灾害链进行深入研究,基于灾害链原理,分析地质灾害漫长链式灾变规律,指出原始地形地貌在地质构造演变及气象水文影响、地震作用和人为作用下形成的环境是导致斜坡地质灾害链的源头因素,崩滑流灾害链中危岩、崩塌、滑坡、泥石流等灾害要素之间的相互关联关系使链的延续成为可能。运用熵权理论对斜坡地质灾害链源致灾因素进行探讨,找出链式灾变规律的主要源头因素,为源头致灾因素的工程治理及防护措施等断链减灾提供依据。Slope geological disaster chain is profoundly studied by introducing the disaster chain theory. An analysis on the long chain disaster law on geological disaster is done based on the disaster chain theory. It is pointed out that the environment which formed in geologic structure evolution,terrain landform evolution,meteorological influence,hydrological influence,earthquake action and human unreasonable activities is the source factor that lead to slope geological disaster chain,and the slope geological disaster chain exists because of the interaction of perilous rock,collapses,landslides and debris flow. The disaster-causing factors of slope geological disasters chain is discussed by the entropy theory,and the main source factors of the chain disaster law is tried to be found out to provide the further research references on chain-cutting disaster mitigation.
