梅岭地质灾害类型与形成机制

Types and Forming Mechanism of Geohazards in Meiling

梅岭是国家级风景名胜区,滑坡、崩塌等地质灾害频发,严重威胁着景区的生态环境和生命财产安全。通过对梅岭地质灾害类型、分布与形成机制的实地调查与分析,结果表明:该区域的地质灾害类型以滑坡、崩塌、危(滚)石和山洪为主,主要分布于人工活动较强的低山丘陵区沿沟谷分布的居民点附近和修建的道路两侧;发育机制与地质地貌有较大关系,更主要是受强降水和人类活动的影响。

Meiling is a national tourist attraction. In recent years, landslide, collapse and other geological disasters occur frequently which seriously threat the ecological environment, life and property safety in the scenic spot. In this research, we analyzed the geological disaster type of Meiling, carried out field survey on the distribution and formation mechanism and concluded that geological disaster types mainly contain landslide, collapse, dangerous rock or rockfall and mountain torrents. They were mainly distributed nearby residential areas along the valleys of low hilly land and both sides of building roads where human activities were strong. Geohazards forming mechanism had close relationship with geologic physiognomy. Furthermore, it was mainly affected by the strong rainfall and human activities.
