| 摘 要： | 贵州喀斯特环境地质灾害类型多样、分布广泛、发性强，其发生、发育过程不但具有明显的季节性，且具有同步叠加、连续发生及交替出现等特点；地质灾害的危害程度、暴发频率也在逐年增大。其形成过程主要受岩性、地貌、灾害性降水和人类经济等条件影响。地球内动力地质作用决定了喀斯特地质灾害的环境背景，如广布的碳酸盐岩和陡峻的地貌特征等。特别是挽近期的构造运动对近、现代地质灾害具有明显的控制作用；人为活动改变了岩（土）体的平衡状态而导致环境地质灾害发生。

| Abstract: | The karst geohazards are characterized by diversity, widespread, sudden attack; they not only have obvious seasonality, but also occur with synchronal superposition, continuous repetition and alternative appearance. They are caused from lithology, geomorphic feature, tectogenetic movement, disastrous rainfall, and artificial geologic process. The endogenic geological processes in geological history laid down a substantial foundation for environmental geohazards; external geologic process from climate and human activity are the key to trigger and accelerate the formation and development of karst geohazards. |
