| 本文以地处云南省滇中北部的永仁县为研究对象，通过资料收集、遥感调查、地面调查以及综合研究的方法，重点研究了区内地质灾害的发育特征和形成条件。研究结果表明：区内主要有滑坡、崩塌、泥石流3种地质灾害类型，滑坡居多，泥石流次之，崩塌最少。全区共有地质灾害点111个，以中小型为主。该区地质灾害是在地形地貌、地质构造、地层岩性、岩土体结构类型、降雨、地震、人类活动等诸多因素的影响下形成的，其中地形地貌、地质构造、地层岩性、岩土体结构类型为地质灾害形成的主要因素，降雨、地震、人类活动则是地质灾害形成的诱发因素。最终，本文认为地质条件因素对灾害形成影响程度最大，其次为降雨因素，最后为人类活动因素。建议根据地质灾害类型、发育特征、分布规律等，因地制宜，加强监测预测，做好地质灾害防治工作。 |

| This paper takes Yongren County， which is located in the north central Yunnan Province， as the research object. Through data collection， remote sensing survey， ground survey， and comprehensive research methods， the development characteristics of geological disasters in the study area are summarized and analyzed， and the formation conditions are explored according to their development characteristics. Research shows that there are three main types of geological disasters in the area： landslides， collapses， and mudslides， with landslides and mudslides being the main types， followed by collapses. There are a total of 111 geological hazard points in the entire region， mainly small and medium-sized. The geological disasters in this area are formed under the influence of various factors such as topography， geological structure， stratigraphic lithology， rock and soil structure type， rainfall， earthquake， and human activities. Among them， topography， geological structure， stratigraphic lithology， and rock and soil structure type are the main factors causing the formation of geological disasters， while rainfall， earthquake， and human activities are the inducing factors for the formation of geological disasters. Finally， this paper believes that geological conditions have the greatest impact on the formation of disasters， followed by rainfall factors and finally human activity factors. Based on the types， development characteristics， and distribution patterns of geological disasters， we should adjust measures to local conditions， strengthen monitoring and prediction， and carry out geological disaster prevention and control work well. |
