摘　　要：我国是地质灾害频发的国家,滑坡地质灾害是其中重要的灾害类型之一,对受灾区居民的安全造成严重威胁。由于历史滑坡地质灾害(如古滑坡)的数据获取途径有限,同时灾害记录的信息并不是很完整,因此不利于开展滑坡地质灾害的历史重建及预测研究,而树木地貌学方法为解决该问题提供了新的思路。本综述对滑坡地质灾害中的树木倾斜、树轮偏心、树轮宽度突变、应力木形成和细胞管腔变化等常见的树木异常指标进行了总结分析;针对不同的树木异常指标,提出了相应的采样策略和灾害事件的识别方法,进而分析还原了滑坡地质灾害事件的形成历史及时空分布;在此基础上,结合环境数据对滑坡地质灾害的诱发因素进行了探讨。总体而言,树木地貌学方法在滑坡地质灾害研究中具有很好的应用前景,能够为滑坡地质灾害的历史重建及预测提供参考方法和理论依据。China is a country with frequent geological disasters,and landslides are one of the essential types of disasters that pose a significant threat to the safety of the residents in the affected areas.However,the limited data on historical landslide geohazards(e.g.,ancient landslides)and the incomplete disaster records hinder research on the historical reconstruction and prediction of landslide geohazards.The dendrogeomorphology method provides a new idea for solving the problem.Therefore,this review analyzes common tree anomaly indicators such as tree tilting,tree ring eccentricity,mutations in the growth of tree ring width,the reaction wood,and variation in the lumen of tree cells in landslide geohazards.Meanwhile,this paper analyzes the corresponding sampling strategies and identification methods of disaster events through different tree anomaly indicators.Then,it analyzes and restores the history and spatial and temporal distribution of landslide geohazard events.On this basis,the predisposing factors of landslides geohazards are discussed with environmental data.In conclusion,the dendrogeomorphology method has a good potential for application in the study of landslide geohazards.It can provide a reference method and theoretical basis for the historical reconstruction and prediction of landslide geohazards.
