摘要:
如何确定人类历史活动稀少、植被覆盖率较高的高寒山区泥石流历史活动次数及时间较为困难。树木年代学分析方法可通过树木年轮生长变化对泥石流活动的响应特征,重建过去一定时间内的泥石流历史活动事件。通过对我国四川省境内贡嘎山东坡磨西河流域内倒灶沟泥石流堆积扇上140个桤木的树木年轮样本取样及树木年代学分析,重建了该沟在过去20 a间的2次较大规模泥石流活动事件(分别为1996年和2005年)和5次小规模洪水(或泥石流)事件。研究结果表明,在过去20 a间,倒灶沟大规模泥石流每隔约10 a便会发生一次,而小规模的泥石流或洪水则每隔2~3 a便会发生一次。同时,研究还发现,磨西河流域内泥石流堆积扇上有利于类...
Abstract:
It is difficult to identify the historical events of debris flow because of the rear human activity and well covering of vegetable in high mountain area. We can date the historical events of debris flow in the past few years according to the reaction of tree ring to the activity of debris flow by dendrochronological method. Based on 140 tree rings from debris flow fan of Daozao debris flow in Moxi basin which locate in the east of M.T Minya Kongka, Sichuan province of China. We dated two big debris flow events(1996 and 2005) and 5 small debris flows or flood events in the past 20 years by analysis these tree rings at University of Silesia, Poland. Results show that there have a reoccurrence of big volume debris flow with the interval time of 10 years and have a reoccurrence of small volume of debris flow or flood the interval time with 2 to 3 years in Daozao gully. At the same time, the result show that the debris flow fans in Moxi basin are suit the growing of Alnus nepalensis (with 1.4 cm width of tree ring) and other species of trees which have the same growth characteristics like Alnus nepalensis, and this research can provide scientific basis to the prevention of debris flow in Moxi basin.
