摘要
该文在分析前人研究资料的基础上，论述了四川盆地周围边缘山地（即四川盆周山地）的泥石流、滑坡等主要山地灾害地貌的面状、线状和点状等平面分布特征，从地质力学角度分析了四川盆周山地大地构造体系的基本特点。进一步探讨了大地构造格局对四川盆周山地灾害地貌在区域分布规律方面的控制和在形成过程中的作用。
This paper expands on the regularity of planar,linear ,and point distribution of the maih nountain calamity landforms such as the debris flow and landslide in the mountains surrounding Sichuan basin. Form the angle of geomechanics it analyzes the basic characteristics of the geotectonic system in mountains surrounding Sichuan basin. Finally , it explores that the geotectonic system has the function of the control over regularity of regional distribution of mountain calamity landforms sur- rounding Sichuan basin and it also plays a role in the course of the formation of mountain calamity landforms surrounding Sichuan basin.
