[ 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.%[目的]为祁连圆柏的抚育改造和管理提供理论依据.[方法]对祁连山寺大隆林区的祁连圆柏林分进行调查,选择标准木进行树干解析,分析祁连圆柏林分的生长过程.[结果]树高、胸径和材积连年生长量达到峰值的时间分别是80、120和 200年.其生长遵循一定规律,自变量树高总生长量与因变量年龄的曲线模型为y=e(R=0.982).胸径总生长量随年龄变化曲线模型为y=eR=0.946),材积总生长量与年龄的回归方程为y=2.2×10χ(R=0.994).[结论]祁连圆柏的生长遵循一定的规律.>
