本文对四川王朗国家自然保护区不同海拔岷江冷杉森林群落内的凋落物总量、各凋落物组分随海拔的变化及其季节动态进行了研究,结果显示,各凋落物组分和总凋落物的年产量在不同海拔间均无显著性差异,年总凋落物量在3 537.18~4 761.84 kg.hm-2.a-1,高于同一地区的相似群落,表明在该区域岷江冷杉林具有相对较高的生产力。总凋落物在不同海拔梯度上具有相似的季节变化规律,但各凋落物组分的季节动态变化不一致。

The forests litterfall is an important component of forest ecosystem biomass,the annual average litterfall can reflect the primary production of forest and is the embodiment of the forest ecosystems function.This paper explored the quantity characteristic and seasonal dynamic of forests litterfall of Abies faxoniana community at altitudes between 2500 and 3500 m in the Wanglang Natural Reserve in southwest China.The results showed that total litterfall and each litterfall components were no significant difference at different altitudes.The total litterfall change in 3537.18～4761.84 kg·hm-2·a-1 from 2500 to 3500 m a.s.l.,higher than the similar community of the same area,which indicated that Abies faxoniana community in this area have a relatively high productivity.There are similar seasonal dynamic in total litter of different altitudes,but not in each litter component.
