贵州构造—岩土体分区及其与地质灾害形成的关系

Zoning of Structure and Rock-Soil Mass in Guizhou and Relations with the Formation of Geological Disaster

岩土体是组成地壳表层的一种地质体,是地质灾害的重要载体和物质基础。本文采用活动论和系统论的观点,以构造为主线,首次提出贵州构造—岩土体分区方案,将贵州划分为赤水、武陵山—乌蒙山、清水江和南盘江4个构造—岩土体区,并将武陵山—乌蒙山构造—岩土体区进一步划分成5个构造—岩土体亚区,分析和归纳总结了贵州岩土体和各构造-岩土体区特征及其与地质灾害发育程度的关系。

Rock and soil mass, a kind of geological body forming the earth crust surface, is the important carrier and material base of geological disaster. With a viewpoint of mobilism and system theory, the suggestion of zoning of structure and rock-soil mass in Guizhou is made for the first time. Guizhou is divided into four structure and rock-soil masses, namely Chishui, Wulingshan-Wumengshan, Qingshuijiang and Nanpanjiang. Wulingshan-Wu- mengshan is further divided into five sub-areas of structure and rock-soil mass. Finally, the characteristics of the structure and rock-soil mass and its relations with the development degree of geological disaster are analyzed and summarized.
