| Other Abstract | 泥石流是西藏山区和河谷地带常见的一种自然现象，当地称为“冰川暴发”。每当雨季和冰雪消融季节泥石流活动频繁，危害较大。因此，开展西藏泥石流研究，掌握其发生、发展与分布规律，探索其防治途径，具有重要的意义。 |
| Abstract | The Xizang area has undergone strong uplift since Neogene. With unique natural conditions favourable to the occurrence and development of debris flows, it is one of the regions where debris flows are most developing and active in China. In Xizhang there are two kinds of water sourcesforming debris, i.e, rainwater and meltwater. The former causes rainfall debris flows, and the latter triggers glacial debris flows. The development and distribution of debris flows in Xizang vary with landforms and climate. In the interior of Xizang, debris flows are not developing for the weather is parching and cold. On the other hand, both types of debris flows are widdy distributed and strong in acitivity in mountainous region of Southeast and South Xizang with a humid and rainy climate,and much meltwater in summer. That is the chief region of debris flows in Xizang. The distribution of debris flows has a vertical zonation. Glacial debris flows orginate in the alpine ice and snow belt; rainfall debris flows in the forest or sparse brush belt. The activity of debris flows in Xizang with a long history is characterzied by rhythm, which is related to the rhythm of the climate and sesmic activity. |
