| 摘 要： | 汶川大地震对地质环境影响很大，由于大地震的影响，其震前震后的地质灾害类型、数量等发生了很大的改变。本文通过搜集前人资料，现场调查，分析了汶川大地震前后汶川县地质灾害的变化。结果表明，地震前汶川县地质灾害类型主要以泥石流为主，地震后，汶川县地质灾害类型主要为崩塌，其次为泥石流和滑坡。地震使汶川县地质灾害数量极大增加，同时，也使得其主要地质灾害类型发生改变。

| Abstract: | The Wenchuan earthquake made a great impact on the geological environment. Because of the impact of a major earthquake, the disaster types and quantity have led to great changes happen before and after the earthquake. In this paper, the collection of previous data, field investigation, analysis of the changes of geological disasters in Wenchuan County of before and after the Wenchuan earthquake. The results showed main types of geological disasters in the main debris flow in Wenchuan County before the earthquake, Wenchuan County main types of geological disasters as landslides, followed by mud--rock flows and landslides, and the earthquake greatly led to increase of the number of geological disasters and made the type change of the main geological disasters. |
