四川汶川发生8.0级强震后,在震中附近山区引发了大量的岩石崩滑、山体滑坡、堰塞湖等次生地质灾害,国土资源部中国地质调查局组织四川、湖北、湖南、陕西、安徽和中国地大的有关专家利用卫星遥感资料,迅速调查次生地质灾害情况,每天上报,供国务院等有关部门决策。本文选择重灾区之一的有代表性的什邡北部山区加以介绍,分析了特殊构造部位与次生地质灾害发生的关系,建立了次生地质灾害遥感解译标志,总结了该区次生地质灾害的主要类型,评价了该区的灾情现状,并提出了合理的防治建议,供同行们切磋。
8.0 earthquake of Wenchuan,Si Chuan Province caused a lot of rockfall, landslides, dammed lake, and other secondary geological disasters near the epicenter in the mountainous areas, China Geological Survey of Ministry of Land and Resources has organized many experts from Sichuan, Hubei, Hunan,Shaanxi,Anhui and China university of geoscience ,using satellite remote sensing data, rapidly surveied secondary geological disasters dued to earthquak, dally reported infomation to the relevant departments of the State Council for decisionmaking. In this paper, choose one of representative of the worst-hit area ,the north mountains of Shifang City, specialy analysised the relationship between structure location and secondary geological disasters ,established signs of secondary geological disasters with remote sensing interpretation, summed up the main types of the secondary geological disasters in the area, assessed the current situation in the disaster area and made a reasonable prevention and treatment recommendations for colleagues compare notes.
