锐齿槲栎

坡向对锐齿槲栎种群的更新有重要影响，光照好的东南坡上的更新情况明显比光照较少的西北坡好。

Influence of the slopes with different directions on population regeneration was also studied , and it showed that the slope direction was one important factor for regeneration .

锐齿槲栎的非结构性碳水化合物含量随着海拔升高而降低，铁橡树中在中、高海拔却略有升高，显示出两种植物碳资源分配和利用策略的不同。

Non-structural carbohydrate content decreased with increasing altitude in Qa , yet which escalated at high and medium altitude for Qs implying there were different carbon resource allocation and use strategies in two kinds of plant .

结果表明：（1）随着海拔的升高，锐齿槲栎叶形态特征在海拔间相对比较恒定，仅低海拔的干重较中高海拔稍大而叶形指数又稍小。

The main results are showed as follow : ( 1 ) The leaf shape and size was relatively constant in Qa along the altitudinal , only the dry weight was higher and the leaf shape index was smaller in low altitude than that in medium altitude gradient .
