| 中文摘要: |
| 贵州是山地省份，地质灾害发生尤其突出，为我国地质灾害高易发区，通过对全省重点地区重大地质灾害隐患进行详细调查，查明了全省威胁100人以上的重大地质灾害隐患发育状况，并对影响因素进行了综合分析研究，得出了：（1）贵州重大地质灾害全省各市州均有发育，其中西部六盘水、毕节和黔西南分布最多，其次为北部的遵义、铜仁，中部、南部和东部相对要少；（2）贵州重大地质灾害规模等级以小型和中型为主，大型以上规模等级的灾害数量少；（3）贵州重大地质灾害类型以滑坡为主，崩塌次之，地面塌陷相对较少，泥石流和地裂缝数量少；（4）岩土体类型变化大、结构松散，地形起伏、坡度变化大是重大地质灾害形成的主要影响因素，构造发育、地层破碎是次要因素；（5）降雨集中是重大地质灾害形成的主要诱发因素；（6）人为活动现已成为重大地质灾害发生的一个重要影响因素。 |

| Guizhou is the geologic disaster prone areas of the country，by detailed survey of important potential geologic disaster of the important areas，the types and distribution of important potential geologic disaster which threaten more than 100 people are known，then the preventions are carried out：（1）the important geologic disaster distribute in very city，the most distribute in Liupanshui，Bijie and Qianxinan，then the Zunyi and Tongren in the north area，the less distribute in the middle，south and east area；（2）the rank of important geologic disaster of Guizhou mainly are small and medium，the big disasters are less；（3）strengthen and accelerate the important geologic disaster prevention is an important method to reduce the geologic disaster hazard；（4）built up the forcsting system of geologic disaster automatic monitoring and weather risk real-time warning；（5）enlarge the coverage of basic geologic disaster and prevention knowledge and improve the prevention ability；（6）strengthen the geologic disaster prevention of mine and reduce the damage of human geologic disaster. |
