Keyword西南地区 滑坡灾害 分布 活动特征 灾害度
Abstract西南地区是我国滑坡发生数量最多、损失程度最大的地区,仅史料记载因滑坡所造成的死亡人数在25000人以上。本世纪80年代以来,平均每年损失约2亿元;目前全区受滑坡灾害或威胁的达200个县(市),近200万人口,60万间房屋,200万亩耕地,500余处矿山,140多个县城,区乡小镇1200多个。文章以史料和调查资料为基础,分析灾害的成因类型,并结合地质背景,划分8个滑坡强烈发育区,5个滑坡中等发育区,5个滑坡微弱发育区;以滑坡发生时间统计其频率,得出全区1930-1965年为滑坡活动宁静期,1966-1990为滑坡活动活跃期,以及其中变异状态。滑坡灾害度评估采用量化模型,考察以自然因素和滑坡现象为主的滑坡频度,灾害损失,以及地区经济发展水平,实现模型的构造采用计算机量化分析,并自动成图,旨在通过自然地貌发生过程和人文经济现象相结合,反映致灾体和受灾体相互作用的结果。西南地区是我国滑坡发生数量最多、损失程度最大的地区,仅史料记载因滑坡所造成的死亡人数在25000人以上。本世纪80年代以来,平均每年损失约2亿元;目前全区受滑坡灾害或威胁的达200个县(市),近200万人口,60万间房屋,200万亩耕地,500余处矿山,140多个县城,区乡小镇1200多个。文章以史料和调查资料为基础,分析灾害的成因类型,并结合地质背景,划分8个滑坡强烈发育区,5个滑坡中等发育区,5个滑坡微弱发育区;以滑坡发生时间统计其频率,得出全区1930-1965年为滑坡活动宁静期,1966-1990为滑坡活动活跃期,以及其中变异状态。滑坡灾害度评估采用量化模型,考察以自然因素和滑坡现象为主的滑坡频度,灾害损失,以及地区经济发展水平,实现模型的构造采用计算机量化分析,并自动成图,旨在通过自然地貌发生过程和人文经济现象相结合,反映致灾体和受灾体相互作用的结果。
Other AbstractIt is an area that landslides and their loses have occupied a predominant in Southwest of China. According to historical records before 1960s, the deaths from serious landslide hazard rose to above 25000. From 1980 onwards, the landslides in Southwest shew more active damage of which the annual loses reached ¥200 million. They are now as a potential hazard threating along 2 million people in 200 country, and above 140 county town, 600 thousand houses, 140 thousand hq of planting land, and 500 mining area. This paper hased on historic document and survey records analyses the landslide formative types. Combing with geological background, their zone classification has been carefully made to figure out 8 intense action regions, 5 moderate regions, and 5 weak ones. For landslide risk assessment it uses quantitative model probing into natural phenomena such as the density of landslide distribution, and geological background data, disaster loses and regionally economic development information which was deliberately organized into the modelling analysis and automatic graph. And the result carried out reflects into influence between landslide occurrence and human activities.
