Abstract:

选取黄土丘陵区3种代表性植被恢复模式的沟谷地样地人工刺槐(Robiniapseudoacacia)林沟谷地(G-Rp),人工柠条(Caraganakorshinskii)灌丛沟谷地(G-Ck)和天然草地沟谷地(G-Ng).通过分析沟谷地5个坡位样带的土壤样品,评价了不同植被恢复模式对沟谷地土壤碳氮磷元素的影响.结果表明3种植被恢复模式对沟谷地土壤有机碳和全氮的含量及储量具有显著的改善作用,对土壤全磷含量及储量略有减少的影响,其中柠条灌丛沟谷地土壤磷相对于对照(坡耕地)减少达显著差异(P<0.05);土壤碳氮磷的含量及储量在沟谷地的空间分布存在显著差异(P<0.05),总体呈由上到下递增趋势(除G-Rp沟底);沟谷地土壤碳氮元素间呈正向和极显著的线性相关关系(P<0.0001).在黄土丘陵区沟谷地地貌单元实施植被恢复,可显著地提高沟谷地土壤的碳汇和氮素储量.
