| 摘 要： | 枯落物层在森林生态功能中具有十分重要的作用。在冀北山区北沟林场搜集了3种典型森林群落枯落物,研究其储量和持水特性。结果表明：3种林分类型枯落物半分解层的储量均大于未分解层;枯落物最大持水量总和为：油松蒙古栎混交林（155.31t/hm2）〉山杨桦树混交林（105.62t/hm2）〉落叶松桦树混交林（88.17t/hm2）;枯落物有效拦蓄量半分解层均大于未分解层,排序为：油松蒙古栎混交林（128.15t/hm2）〉山杨桦树混交林（82.27t/hm2）〉落叶松桦树混交林（69.22t/hm2）;总的有效持水量为：油松蒙古栎混交林（132.01t/hm2）〉山杨桦树混交林（89.39t/hm2）〉落叶松桦树混交林（74.95t/hm2）;枯落物各层持水量与浸泡时间呈很好的对数关系。总之,油松蒙古栎混交林保持水土效果最佳。 |

| Abstract: | Litter layer plays a very important role in forest ecosystem function.This study,in the northern mountain of Hebei Province,collected three typical forests litter,and analyzed their reserves and water-holding characteristics.The results showed that: the reserves of the three forest types of semi-decomposed litter layer are greater than that of the undecomposed layer;maximum water holding capacity of litter sum: the mixed forest of Pinus tabulaeformis and Quercus mongolica(155.31 t/hm2)>the mixed forest of P... |
