摘　　要：在研究区域构造的基础上,通过实测地质剖面、采集定向标本、室内薄片观察、显微构造观测和岩组分析,研究地质构造对滑坡的控制作用。结果表明,宽大的北西向石狮村韧性剪切带和活动期次较多的脆性断层叠加部位是产生滑坡、崩塌和泥石流的高危地段。Based on the regional tectonics, the role of tectonics in controlling the landslides is analyzed by constructing meas ured geological sections, collecting oriented samples, observing indoor flakes, observing microstructure and analyzing petrofabric. The results show that landslides, avalanches and mudflows are most likely to occur in the large ductile shear zones and the places with superimposed brittle faults in Shishi.
