摘要
本文将贵州西部约２８８６２ｋｍ２范围内近１８００处崩塌、滑坡总结为受塑流—拉裂、弯曲—拉裂、蠕滑—拉裂、滑移—弯曲和滑移—压致拉裂等五种地质模式或复合模式控制．并指出，区内崩塌、滑坡主要由塑流—拉裂、弯曲—拉裂、蠕滑—拉裂等地质模式演变而成，表现出较强的地层控制性；由于航片解译的局限性，未对滑移—压致拉裂模式举例讨论，但肯定其的确存在。同时阐明，近几十年来发生的滑坡主要为受蠕滑—拉裂地质模式控制的松散层滑坡．
Based on the study of Devolution and Landslip in an area of 2862 km2 in western Guizhou. five geological models, i. e. plastic flow-pully apart, flexion-apart, creep slidingpull apart, slip-flexion and slip-pull apart resulting from compression, and their complexes can be established. It is noticed that the devolution and Landslip in this area were formed mainly through evolution of plastic flow-pull apart, flexion-pull apart and creep slidingpull apart and were controled apparently by certain strata, and that the recent landslips were dominantly as creep sliding-pull apart.
