摘要
通过地质灾害野外调查和室内资料分析,结合前人研究成果,系统梳理总结了南澳岛地质灾害发育特征和形成条件。结果表明:南澳岛地质灾害类型主要是以小型崩塌、滑坡、不稳定斜坡失稳为主,呈点多面广、突发性强、危害性大的特点,集中分布在城乡人口密集区、岛内交通主要干线两侧的斜坡区和挖山采土采石区;南澳岛地质灾害的发生受地形地貌条件、气象水文条件、地层及地质构造条件和人类工程活动的综合影响,其中人类工程活动是诱发地质灾害发生的主导因素;南澳岛地质灾害的防治宜加强高风险区管控和隐患排查治理,规范人类活动工程,最大限度地减少和防止地质灾害引发的损失,保障当地人民群众生命财产安全。
Through the field investigation and indoor data analysis of geological disasters,combined with the previous research results of the predecessors,the development characteristics and formation conditions of geological disasters in Nan'ao Island were systematically sorted out and summarized,and the gap of geological disasters analysis on Nan'ao Island was supple-mented.The results show that:the occurrence of geological disasters in Nan'ao Island is affected by the comprehensive influ-ence of topographic and geomorphological conditions,meteorological and hydrological conditions,stratigraphic and geological structure conditions,and human engineering activities,among which human engineering activities are the leading factors induc-ing the occurrence of geological disasters.The prevention and control of geological disasters on Nan'ao Island should strengthen the control of high-risk areas,the investigation and management of hidden dangers,and the standardization of hu-man activity projects so as to minimize and prevent losses caused by geological disasters and ensure the safety of local people’s lives and properties.
