| 摘要: |
| 以长白山主要支脉张广才岭和哈达岭山系为研究对象，通过对各林分类型凋落物现存量及其
组成分析，探讨不同林分类型凋落物现存量的差异。结果表明，天然林凋落物平均现存量为 5.97 t/hm2；
人工林凋落物平均现存量为 5.96 t/hm2；在天然林各调查群落中，阔叶混交林和落叶阔叶纯林面积占有较
大比例，凋落物平均现存量分别为 6.11 和 5.99 t/hm2；其针叶混交林面积最小，平均现存量仅为 2.74 t/
hm2；在人工林各调查群落中，针叶纯林面积最大，平均现存量为 6.09 t/hm2；针阔混交林面积最小，平
均现存量为 5.76 t/hm2。在人工林、天然林未分解层各组分中，均表现出凋落叶（阔叶 针叶） > 凋落枝
（阔枝 针枝） > 杂物的趋势。 |

| Abstract: |
| Zhang Guangcai and Hada Mountains are the main branches of Paekdusan. Through the analysis
of litter accumulation (LA) and composition in various forest types, this paper explored the differences of LA in
different forest types. The average of forest LA in natural forest was 5.97 t/hm2, while the plantation forest was
5.96 t/hm2. The mixed forest of broad-leaved and the pure forest of broad-leaved accounted for a large proportion
of various forest community of natural forest, which the average LA was 6.11 and 5.99 t/hm2, respectively. The
average of LA was only 2.74 t/hm2 in coniferous forest, which was the minimum proportion. In plantation forest,
the LA of coniferous pure forest was 6.09 t/hm2, which possessed a large proportion. The mixed forest of coniferous and broad-leaved occupied the lowest proportion, which the number of average LA was 5.76 t/hm2. There was
a trend that leaf LA was higher than the branch LA, while trash LA was lower than branch LA in the un-decomposed layer of natural forest and plantation forest. |
