摘　　要：新罗区是福建省地质条件复杂、地质灾害最严重的县区之一。地质灾害的主要类型有不稳定斜坡、滑坡、崩塌、泥石流、岩溶地面塌陷、采空区地面塌陷六种。其中滑坡、岩溶地面塌陷是区内地质灾害的最主要类型,灾害呈现点多、面广、规模小、稳定性差的特点。野外调查表明,新罗区地质灾害的形成是多种因素相互作用的结果。通过对新罗区地质灾害的形成机理分析研究表明,地形地貌、地层岩性、地质构造以及水文地质等因素是地质灾害形成的基础因素;降雨及人类活动等因素是地质灾害形成的动态因素。XinLuo district is one of the counties with complex geological conditions and the most serious geological disasters in Fujian province. There are six main types of geological disasters, including unstable slopes, landslides, avalanches, debris flow, karst ground collapse and ground subsidence, of which landslides and karst ground subsidence are the most important types of geological disasters in the region, because of the numerous disaster points, a wide range of area, small scale and poor stability. The survey showed that the formation of the geological disasters in XinLuo district is the result of the interaction of many factors. By studying the formation mechanism of geological disasters in XinLuo district, it shows that topography, lithology, geological structure and hydrogeological is the fundamental factors in the formation of geological disasters; factors such as rainfall and human activities are the dynamic factors in the formation of geological disasters.
