摘　　要：利用Pilodyn对白榆活立木进行探测,室内测定白榆木材的基本密度、纤维长度和纤维宽度,对白榆Pilo-dyn值与木材的基本密度、纤维长度和宽度进行统计分析.结果表明:白榆Pilodyn测定值与木材外侧基本密度、全株木材基本密度呈极显著负相关,相关系数分别为-0.546和-0.607,整株木材基本密度对白榆Pilodyn值的贡献率为83.38%,依此建立了Pilodyn值与整株木材基本密度间的线性回归模型.Pilodyn was used to measure the vigor of living trees of Ulmus pumila in the field.Wood basic density,fiber length and fiber width were measured.The results showed that the value determined by Pilodyn was significantly negative correlated with outer wood basic density and the whole wood basic density,the correlation coefficient was-0.546 and-0.607 respectively.The contribution rate of whole wood basic density for Pilodyn value was 83.38%.The linear regression model between Pilodyn value and the whole wood basic density was built.
