摘要
根据福安市地质灾害复核调查的资料,统计分析了该市十多年来地质灾害发生的现状,研究地质灾害发生与地形(地貌)、岩土体、降雨、人类工程活动等因素的密切关系,总结出大多数地质灾害点分布于自然坡度为25°～45°的陡坡地段,滑坡崩塌发生多为5～8月份的雨季或台风暴雨季节,人类工程活动致灾因素主要是削坡建房等,并提出相关的防治建议。
Based on the check to investigation of geological hazards in Fuan City, the paper analysed the geological disaster situation for over ten years and studyed the inducement of geologic hazards be a close relation with the factors, terrain （topography）, rock and soil, rainfall, human engineering activities. The paper presents most of geological hazards distributing in the steep slope of 25°-45°, collapse and landslide occurred typhoon and rainy season of may-august , and the disaster-causing factors of human engineering activities be cutting slope and building. The author put forward the related prevention and cure measure.
