中文摘要: 近年来,在全球气候变暖的背景下,我国突发性、局地性极端强降雨事件频发,加之城镇化进程中的人类社会经济活动,导致发生了大量的地质灾害事件,地质灾害造成的人员伤亡占我国自然灾害造成人员伤亡总数的比例呈逐渐上升趋势。本文以十二五期间我国发生的地质灾害为主要研究对象,搜集了全国省级国土部门的权威数据,通过数理统计,以及对孕灾条件和诱发因素的分析等,研究总结了20102015年(十二五)期间全国发生的地质灾害的总体情况及特征: ①在全国发生的64 530起地质灾害中,滑坡、崩塌、泥石流为主要灾害类型,中小型灾害最为发育; ②强降雨是地质灾害的主要诱发因素,汛期降雨型地质灾害在地域上具有随时间由东南向西北逐渐推移的特征;③地质灾害造成的危害具有向低人员伤亡、高财产损失方向发展的趋势。研究结果对今后一段时期全国地质灾害防治工作部署提出了建议。
英文摘要: In recent years,under the impact of global warming,a larger number of geo-hazards were triggered by the frequent occurrences of sudden and regional extreme heavy rainfall events as well as the human society and economic activities during the process of urbanization. The portion of casualties caused by geo-hazards gradually increases in the total number of casualties caused by natural disasters in China. In this study,the authoritative data about geo-hazards occurred in the 12th five-year plan were collected from the provincial department of land and resources. By mathematical statistics,and the analysis of the conditions of inducing disasters,following characters of geo-hazards occurred in China in the 12th five-year plan can be summarized: ①In 64 530 geohazards, landslide,avalanche and debris flow are the main types,and the samll and middle classes of geohazards occurred are the most; ②Heavy rainfall is the major triggering factor,and the occurrences of rainfalltriggered geo-hazards move from the southeast to the northwest gradually as time during the flood period; ③The development trend of casualty and economic loess caused by geo-hazards were decreasing and increasing. In the end,the recommendations about the work arrangement of geo-hazards in the next period.
