利用临沂市赤松、黑松、油松测高木资料，对３树种平均树高差异性进行了检验。求算出各树种的树高曲线方程，并采用松类二元立木材积式导算出各树种的一元立木材积表。经检验分析，各树种一元立木材积表的精度均明显高于１９７５年编制的松类一元立木材积表。 Using the data of Pinus tabulaeformis, Pinus thunbergii and Pinus tabulaeformis in Linyi City, the average tree height difference of the three tree species was tested. Calculate the tree height curve equation of each tree species, and use the pine bivariate timber integrated guide calculate the tree species of one yuan timber volume table. According to the test and analysis, the precision of one-dimensional standing timber volumetric table for each species was significantly higher than that of the one-standing pine standing volume table compiled in 1975.
