摘　　要：树木年轮资料具有定年准确、连续性强、分辨率高和分布广泛等特点。研究采用WinDENDRO年轮分析系统对陕西省楼观台实验林场和陕西省宁东林业局297个木芯样本的年轮宽度进行分析,通过年轮自动识别和人工判读确认,并对部分出现异常的样本数据进行交叉定年,得到了较为准确的树木年龄和直径连年生长量数据,有效补充了建立树木生长模型的数据种类和精度。同时,研究选取50年油松的木芯样本分析结果,对其直径连年生长量、早晚材生长率和不同方向的直径生长量进行了应用分析。Tree-ring data has the characteristics of high accuracy,strong continuity,high resolution,and wide distribution.297wood cores were analyzed using WinDENDRO image system for ring width analysis regarding age and annual diameter increment data,which can effectively improve the variety and accuracy of data for tree growth modeling,with the methods of automatic identification,manual interpretation,and cross-dating.Wood cores of50-year Pinus tabulaeformis were applied for analysis of diameter current annual increment,earlywood and latewood ratio,and diameter increment from different directions.
