摘要
树轮地貌学以其定年准确、分辨率高和时间跨度长等特点在地表过程的研究中具有极其重要的作用。树木年轮可以作为一个可靠的工具来获得滑坡过去活动的历史证据,进而解释现在正在发生的并窥探滑坡的变形信息。本文对国内外树轮地貌学方法在滑坡事件研究中的现状和取得的成果进行总结,重点阐释了树轮地貌学的原理和树轮地貌学重建滑坡活动迹象与时空分布的研究进展,并讨论了该方法存在的不足,展望了我国利用树轮地貌学开展滑坡事件研究的前景。
Dendrogeomorphology is now playing an important role in the study of geomorphic processes because of such characteristics tree ring have：accurately dating,high resolution and long time span.Some previous researches have shown that tree rings can be used as a reliable tool for historical evidence of past landslides,which can explain what is happening now and detect landslide deformation in the future.The paper reviewed the current situation and achievements of landslide studies which use dendrogeomorphological methods,especially the principles,the reconstruction of landslide activity and spatio-temporal distribution were illuminated.Finally,the shortcomings of this method were pointed out and the future development prospects were looked forward to.
