| 摘 要： | 利用浑善达克沙地白音敖包采集的白扦树芯样本，使用传统宽度测量手段和图像分析手段建立了研究区域采样点的全轮、早材、晚材宽度年表。对比分析结果表明，研究区域内基于图像分析手段和传统宽度测量手段所获取的全轮宽度数据不存在明显差异。基于图像分析手段建立的全轮、早材及晚材宽度年表之间在全频域、高频域和低频域的相关系数均呈显著正相关，且三种年表在低频变化上比在高频域更为一致。过去142年以来，全轮、早材、晚材宽度年表均具有2个低值阶段和2个高值阶段，且3个年表间的高低值变化阶段基本一致。与当地气象资料的相关分析结果显示，全轮、早材、晚材宽度年表均对气温表现出负相关，对降水变化的响应则不明显。而早材宽度与气温表现出的较高相关系数还说明了基于图像分析手段获取的该种数据具有作为气候代用资料的价值。
