摘要
为揭示普安县地质灾害发育的地理背景,统筹人与自然和谐发展,利用1950-2010年普安县国土资源局实时监测数据,从地形地貌、地层岩性、地质构造、水力条件及人类工程活动等方面分析了普安县地质灾害分布特征及形成机理。普安县地质灾害类型主要有滑坡、泥石流、崩塌和地裂缝等,呈现点多面广、分布不均和相对集中等特点,其中滑坡116处、泥石流3处、崩塌30处和地裂缝22处,以小型规模地质灾害为主,其次是中型,大型和特大型较少,提出了防灾减灾的对策与建议。
To reveal the geological background of geological disaster development and keep harmonious development between human with nature,the distribution features and formation mechanism of geological disaster in Pu＇an County were analyzed by using the real-time monitoring data of Pu＇an Land Resources Bureau from aspects of conditions of landform,stratum lithology conditions and geological structural conditions,hydraulic conditions,human engineering activities and so on.There were various types of geological disasters in Pu＇an,Mainly including landslide,debris flow,collapse and ground fissure.The distribution of geological disasters presented the characteristics of overing a broad,uneven distribution and concentration relatively.It included 116 landslides,3 debris flows,30 collapses and 22 ground fissures.The main portion was Small scale of geological disasters,the second is medium,the large and super large is less.The countermeasures and suggestions of disaster prevention and mitigation were put forward as well.
