以空间代替时间的方法,对1～10龄梭梭人工林进行生长状况调查,分析了梭梭各生长指标的变化规律。结果表明：随着林龄的增加,梭梭冠幅、树高、地径以指数方程增长,当年生长量以二项式函数变化,地上生物量以幂函数增加;树高、地径和地上生物量之间存在极显著正相关关系;梭梭枝条当年生长量在第4年达到最大值。

Based on the investigations on growth situations of 1~10-year Haloxylon ammodendron plantation,the changing rule of growth indexes for Haloxylon ammodendron has been analyzed by use of spatio-temporal substitution method.The results show that as stand age increasing,crown width,tree height and ground diameter increase in the exponential equations and the above-ground biomass increases in the power function while the current annual increment in the binomial equation.There is significant positive correlations among tree height,ground diameter and above-ground biomass.In addition,the current annual increment peak of the branches is in the forth year.
