| 摘 要： | 选择辽东地区不同林龄、坡向的日本落叶松人工林,采集林下凋落物,对其蓄积量和自然含水率、最大持水率、最大拦蓄率等持水性能进行研究,探索不同林型凋落物的持水性能。结果表明:林下凋落物蓄积量和持水性能都表现为半分解层大于未分解层。凋落物蓄积量为26.91～59.47t.hm-2,中龄林阴坡的蓄积量最大,幼龄林阳坡的蓄积量最小。林下凋落物的持水率为169.54%～292.57%,近熟林阴坡的林下凋落物持水率最大,幼龄林阳坡的林下凋落物持水率最小。对试验数据的细致分析和公式拟合,得到日本落叶松人工林凋落物的吸水速率与浸泡时间之间存在WA=atb的关系式。 |
| 关 键 词： | 日本落叶松 凋落物 持水量 持水率 吸水速率 |

| Abstract: | Different ages and slope approach of Larix Kaempferi forests plantation of eastern region in Liaoning Province were chosen,and the litter under the forests were gethered.The vo1ume and natural water content,the maximum water-holding percentage,the maximum interception rate and so on had been researched in this paper to make summary the water-holding properties for different forest types.It was shown that the vo1ume and water-holding capability of the litter layer for the 6 forest types were all indicated to... |
| Keywords: | Larix Kaempferi litter layer water-held water-holding rate rate of water absorbability |
