| 摘 要： | 研究结果表明，椴树叶分解过程适合用指数衰减方程来表达，随海拔和植被类型的上升，在1－5号标准地，椴树叶分解常数分别为－0．391，－0．339，－0．257，－0．198和－0．125，即随海拔升高，分解速度下降，光水条件的实验表明，60％－80％的庇荫条件下，分解较快，浇水多的比浇水少的分解快，在实验区条件下，水分条件比光照条件影响更明显，与红松针叶的分解实验相比，二者规律极为相似，而且分解速率相差甚微。 |

| Abstract: | A 4-year field experiment was carried out in the Changbai Mountain to study the decomposition process of Tilia amurensis leaf and its affecting environmental factors. The results reveal that the decomposition process of Tilia amurensis leaves could be expressed by an exponent equitation. With the increase of elevation and the change of vegetation types, the decomposition rate in 1-5 standard experimental fields was -0.391, -0.339, -0.257, -0.198 and -0.125, respectively, indicating that the decomposition rate was decreased with ascending elevation. The maximum decomposition took place when the environment was in the shadow of 60%-80%. The leaves were acceleratively decomposed when the tested moisture was increased. Moisture affected the decomposition process more strongly than light. |
