摘要/Abstract

摘要：

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(Robinia pseudoacacia)林沟谷地(G-Rp),人工柠条(Caragana korshinskii)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.

Abstract:

In this study, three representative vegetation restoration patterns were selected in gully areas including an artificial Robinia pseudoacacia forest gully (G-Rp), an artificial Caragana korshinskii shrubland gully (G-Ck), and a natural grassland gully (G-Ng). Soil samples were collected along five gully position transects on each gully. The study evaluated the effects of three revegetation types on the soil carbon, nitrogen and phosphorus of the gully areas. Results indicated that three revegetation types in the gully areas could significantly improve soil organic carbon and soil total nitrogen contents and storages, and slightly reduce soil P contents and storages. G-Ck significantly reduced soil P contents and storages compared with CK (slope cropland) (P<0.05). The spatial distributions of soil C, N, P contents and storages were significantly different among three gully areas (P<0.05). There was a significantly and positively linear correlation between soil C and N (P<0.0001). Therefore, the implementation of revegetation in gully area, as one of important geomorphic unit, can significantly increase carbon sequestration and N stocks.
