摘　　要：通过对活立木采用Pilodyn（无损检测仪）进行野外删试，并与用实验室测定的木材基本密度、木材管胞长度和宽度比较。结果表明：华山松南北方向上Pilodyn探测值没有显著差异，与木材外侧基本密度、木材基本密度得到的检验结果一致。探测值与木材外侧基本密度及木材基本密度实测值间存在极显著的相关关系；多元线性回归方程中，木材密度的贡献率最大（52．86％～63．74％）。通过一元线性回归方法建立Pilodyn探测值估测木材密度的模型。Pilodyn测定值不仅能估测华山松外侧木材基本密度，同时也能够估测华山松整个径向的木精基本吝囔，In order to research the relation Pilodyn penetration and wood properties,the living tree of Pinus armandii was penetrated by Pilodyn in both south and north directions in the field. The wood basic density and fiber length and width of increment core were measured in door. Through the analysis of Pilodyn penetration, the basic density of increment core,fiber length and width, the results showed that the Pilodyn penetration of Pinus armandii had no significant differences in the north and south directions. The result was the same as outer wood density and basic density and with outer wood density. Pilodyn penetration had highly significant correlation with basic density. The biggest contribution rate to the multiple regression equation was wood density （52.86%--63.74% ）. The model using the average of Pilodyn to estimate wood basic density was made through a linear regression metted. The Pilodyn penetration could estimate the average of outer wood density in an entire radial direction in living tree of Pinus armandii. It could also estimate the basic density in an entire radial direction.
