摘　　要：辽阳地区地质灾害分布较广,对辽阳人民生产及生活构成巨大威胁。本文通过野外调查和遥感数据,研究辽阳市地质灾害与人类工程活动、植被覆盖、地质构造、降水、地形地貌、岩土体类型等孕灾因素的关系。辽阳东部、南部丘陵地貌形成的地势高差为崩塌发育提供先决条件;软土在地下不同程度的发育为工程建设增加施工难度;辽阳东部、南部地震活动时刻对人民生产生活带来威胁,最为关键的是人类不良工程活动,由其导致植被破坏、不合理灌溉等诸多孕灾因素叠加后,最终形成地质灾害。There are many geological disasters in Liaoyang area.They are great threats to the production and life in Liaoyang.Based on the field investigation and remote sensing data,this paper studies the relationship between geological disasters and influence factors.The influence factors include human activities,vegetation cover,geological structure,rainfall,landform and geomorphology,rock soil mass types and other factors in Liaoyang.The difference of terrain and elevation provides the prerequisite for collapse in the east and south of Liaoyang;the development of underground soft soil increases the difficulty of construction;seismic activity poses a threat to production and living in the east and south of Liaoyang.The important key is the bad engineering activities,which leads to vegetation destruction,unreasonable irrigation and so on,and then to form the geological disasters.
