The dating of past landslide events is one of the most crucial aspects of landslide research, leading to a better understanding of past landslide activity. Landslides can be extremely dangerous natural hazards, and thus, solving the relationships between their activity and climate variations is of high importance. For these purposes, data about past landslide activity are fundamental for such analyses. Various methods of landslide absolute dating exist, but the most precise approach that dates back several centuries is based on tree-ring analysis (dendrogeomorphology). Landslide movements can affect the growth of trees in response to specific growth disturbances. Although dendrogeomorphic methods are successfully used for dating other geomorphic processes, their use in landslide research is actually the most frequent. Dendrogeomorphic research on landslides is strongly influenced by general approaches of landslide signal extraction from tree-ring series of disturbed trees and by the type of landslide (varying by morphology, material and mechanism of movement). This study provides an overview of basic aspects of dendrogeomorphic research on landslides, and more specifically, it reviews basic tree-ring-based approaches of landslide dating. Presented review focuses on various landslide types and their effect on dendrogeomorphic dating. This review is built from the extensive database of all accessible dendrogeomorphic studies of landslides from 1893 to 2020. Moreover, recommendations for specific sampling and approach choice in individual landslide types are presented. Finally, limits of tree-ring-based approaches are presented, including provided proposals for further research.

不同滑坡类型的树突形态学研究

过去滑坡事件的年代测定是滑坡研究最关键的方面之一，可以使人们更好地了解过去的滑坡活动。滑坡可能是极其危险的自然灾害，因此解决滑坡活动与气候变化之间的关系非常重要。为此，有关过去滑坡活动的数据对于此类分析至关重要。存在多种滑坡绝对测年方法，但是可以追溯到几个世纪之前的最精确的方法是基于树轮分析（树状形态）。滑坡运动可以响应特定的生长干扰而影响树木的生长。尽管树状地貌方法已成功用于对其他地貌过程进行测年，但实际上它们在滑坡研究中的使用最为频繁。滑坡的树状形态研究受到从受干扰树木的树环系列中提取滑坡信号的一般方法以及滑坡类型（随形态，材料和运动机制的变化）的强烈影响。这项研究概述了滑坡树状地貌研究的基本方面，更具体地说，它回顾了基于树环的滑坡测年的基本方法。提出的评论集中于各种滑坡类型及其对树状地貌测年的影响。本文是从1893年至2020年对滑坡的所有可访问的树状地貌研究的广泛数据库中建立的。此外，还针对个别滑坡类型提出了具体采样和方法选择的建议。最后，提出了基于树环的方法的局限性，
