Research on the Growth Characteristics of Sabina
摘要
Abstract
[ Objective ] The theoretical basis of the improvement and management of Sabina was provided through the research. [ Method ] The stand of Qilian Sabina in the Sidalong Forest Zone in Qilian Mountain was investigated the growth processing of the tree was mastered through the analysis of the standard tree selected. [ Results] The time of the peak value of annual growth amount the height, the diameter and the volume was in the 80th,120th and 200th year. The growth the tree followed a certain law and the curve model of total growth amount of the independent variable-tree height and the dependent variable-age was y = e(2.4５98-61.２06/x) (R2=0.982); total diameter and age, y= e（3.329 4-124.00/x） ( R2 =0.946) and the regression equation of total volume growth amount and age was y = 2. 2 × 10-8x2 770 7 (R2 = 0.994 ). [ Conclusion ] There was a certain law in the processing of Qilian sabina.关键词
