地衣形态量计在同震滑坡研究中的应用
|
摘要
阐述了地衣形态量计法的基本原理和各种不同的具体量计方法及其在同震滑坡研究中的应用方法，指出将该方法应用于同震滑坡研究中，可以帮助提供地震时间、震中、地震频度、地震影响范围和地震断层的一些信息．
The basical principle of lichenometry is that lichens become larger with increasing age, and their size may be proportional to the age of the substrata on which they are growing. Depending on the degree of control over the determination of the lichen age-sire relationship, various kinds of dating are possible. In uncontrolled situation it is possible to distinguish between coseismic landslides of different age, assigning relative ages to each. At a more controlled level, it is possible to produce dates for coseismic landslides. The applications of lichenometry in research of coseismic landslides can help to get information of time, location, regional frequency and affected area of earthquakes and the location of seismic faults.
