摘要/Abstract

摘要： 本文对次生蒙古栎林中的灌木层及主要灌木树种(毛榛子、溲疏和刺五加)在林分养分生物循环中的地位与作用进行了研究。研究结果表明,虽然灌木层在生物量、养分量、存留量、归还量等方面在林分中都次于乔木层,但循环速率为0.68,高于乔木层(0.60),又高于林分(0.64),在林分养分步入良性循环中起着重要的不可缺少的作用。毛棒子和溲疏是灌木中的优势或亚优势树种,是在养分良性循环中具有突出贡献的树种,是重点保护的树种。刺五加在养分循环中,养分存留的比较多,归还比较少、循环速率比较低,具有消耗地力并具有药用的灌木,在此林分中既应保护、维持,又要加以控制。

Abstract: The status and role of the shrub layer and main shrub species in the nutrient cycling of the mongolian oak forest were stated in this paper. The results show that the shrub layer's cycling rate is 0.68 which was more than the arbor's (0.6) and the forest's (0.64) although it is less important than the arbor layer in biomass, nutrient content, remained content, returned content etc. The shrub layer have a important role in promoting the nutrient cycling of the forest. Corylns mandshurica and Deutyia amurensis are dominant or Sub-dominat shrub species which should be protected because they Play an important role in the nutrient cycling, Acanthopanax senticasus matains more nutrient and the cycling rate is low in the nutrient cycling. It exhausted the soil but can be used as a kind of drug. So it should be protected and on the other hand should be controled.
