| 摘 要： | 构造-地貌-气候耦合是现代地球系统科学研究的热点之一。大量地质事实表明,构造、地貌、气候与地质灾害的发生密切相关,而三者的阶段性耦合,即地文期-构造节律-气候旋回耦合,在很大程度上决定了地质灾害在时间分布上的群发和空间上的群集。从地文期-构造节律-气候旋回的关系及耦合作用的分析入手,通过地文期、构造节律、气候旋回与地质灾害的关系论述,建立了地文期、构造节律、气候旋回与地质灾害的耦合关系模式。依据现有资料,对三峡地区滑坡的群(高)发与地文期、构造、气候的耦合关系进行了初步分析,并就如何加强这方面的研究进行了讨论。

| Abstract: | Tectonic-physiognomy-climate cycle coupling is one of the focus of modern earth system science.A mass of geological facts suggest that geological hazards can be consanguineously related to tectonic,physiognomy and climate.Tectonic-physiognomy-climate cycle coupling in stage means the physiography stage-tectonic rhythm-climate cycle coupling,and dominates the conglomeration of geological hazards both on space and time.In this study we establish the coupling model of physiography stage,tectonic rhythm,climate cycle and geological hazards,based on the coupling and relationship between physiography stage,tectonic rhythm,climate cycle and effects which they have on the occurrence of geological hazards.Based on the geological data,we carry out a primary analysis of the relationship between the physiography stage-tectonic rhythm-climate cycle coupling and the occurrence of the landslides in the Three Gorges area.Besides,we also discuss on how to further this kind of research. |
