Abstract The aim of our study was to compare patterns of tree-ring eccentricity developed in Norway spruce trees as a result of landsliding with the one caused by the prevailing wind (in 2 study sites), and with the normal growth of trees (in 2 reference sites). We sampled 20 trees per study site and 10 per reference site. Two cores were taken from each tree (120 cores in total) from the upslope and downslope, windward and leeward sides of stems. Ring widths measured on opposite sides of stems were compared using the method of percent eccentricity index. Graphs of the index obtained for individual trees were analysed. Statistical indicators were calculated for a percent eccentricity index. Disturbance events were dated and the response index was calculated. The results show that the patterns of eccentricity developed as a result of the prevailing winds and due to landsliding differ from one another and from the reference sites. The results suggest that the impact of the prevailing wind on tree growth is more severe than the impact of landsliding. The difference may result from the slow-moving character of the landslide under study. The results, however, indicate that wind impact should be taken into account in dendrogeomorphic research and that the impact of mass movements should be considered in dendroecological studies on wind.

我们能否区分由山体滑坡和盛行风造成的树木年轮偏心率？树木年代学约会的后果

摘要 我们研究的目的是比较挪威云杉树由于滑坡与盛行风引起的山体滑坡（在 2 个研究地点）以及树木的正常生长（在 2参考网站）。我们在每个研究地点取样了 20 棵树，每个参考地点取样了 10 棵树。从茎的上坡和下坡、迎风侧和背风侧从每棵树上取两个芯（总共 120 个芯）。使用百分比偏心指数方法比较在茎的相对侧测量的环宽度。分析了为单个树木获得的指数图。计算偏心率百分比的统计指标。干扰事件被标注日期并计算响应指数。结果表明，由于盛行风和滑坡而形成的偏心模式彼此不同，也与参考地点不同。结果表明，盛行风对树木生长的影响比山体滑坡的影响更为严重。这种差异可能是由于所研究滑坡的缓慢移动特性造成的。然而，结果表明，在树状地貌研究中应考虑风的影响，在对风的树状生态学研究中应考虑群体运动的影响。这种差异可能是由于所研究滑坡的缓慢移动特性造成的。然而，结果表明，在树状地貌研究中应考虑风的影响，在对风的树状生态学研究中应考虑群体运动的影响。这种差异可能是由于所研究滑坡的缓慢移动特性造成的。然而，结果表明，在树状地貌研究中应考虑风的影响，在对风的树状生态学研究中应考虑群体运动的影响。
