摘要
米脂县是陕西省地质灾害较严重的地区之一。地质灾害点数量多,规模小,活动频繁,危害程度大,已造成巨额的经济损失和大量的人员伤亡,严重地制约着当地经济、社会的可持续发展,威胁着人民群众生命财产安全。文中分析了米脂县地质灾害的主要类型及特征,进行了地质灾害易发程度分区,总结了地质灾害的成因机理。认为该县地质灾害的发育与地形地貌、地质构造、降水和人类不规范工程经济活动密切相关。随着人类活动的日益加剧,人为因素已成为地质灾害发生的主导诱发因素。为此,文中提出米脂县地质灾害的防治应突出“以人为本”,坚持预防为主,避让与治理相结合,同时要不断规范人类工程经济行为,合理利用地质环境,提高当地群众的防灾减灾意识和自我保护意识,逐步建立和健全群专结合的地质灾害监测预警系统。
Mizhi, country is one of the areas greatly suffering from geologic disasters in shaanxi province. Loess slides, collapses and debris flows take place frequently and widely, which cause considerable loss of lives and properties. It is suggested that the geologic disasters forming cause and mechanism are closely related to geography, rainfall, geologic structures, and human engineering and economic activities. Artificial factors have become leading ones with the development of human activities. It is very important for the local people to have the knowledge of preventing geologic disasters and to complete the system of geologic disasters monitoring.
