| 摘 要： | 树木年轮定年准确、连续性强、分辨率高，并且易于获取复本，已经成为过去气候变化研究的主要手段之一。在沙漠地区，受气候条件的限制，树轮研究工作开展的较少。通过分析腾格里沙漠南缘油松树木年轮宽度的变化及其对气候因子的响应，发现夏季（6~8月）温度以及年降水量是当地油松生长的重要限制因子。对树木年轮标准化年表的功率谱分析表明，树轮记录具有2.6 a，7.5 a，14 a以及16.5 a的显著周期，其中2.6a以及7.5a周期的树轮指数变化，可能与ENSO的周期有关。

| Abstract: | Dendroclimatology approach is significant in study on climatic changes for its precise dating,high continuity,high resolution and easily obtained duplicates.However,in desert area only less dendroclimatological work have been conducted limited by climatic conditions.Analyses to the STD chronology and its response to climatic changes suggested that the summer temperature(June-August) and year precipitation are the main limited factors to the Pinus tabulaeformis growth in south margin of Tengger Desert.Besides,power spectrum analyses suggested that STD chronology had significant periodicities of 2.6 a,7.5 a,14 a,and 16.5 a.Among which the periodicities of 2.6 a and 7.5 a are possibly associated with ENSO,which affect tree growth through climatic changes. |
