Abstract

ABSTRACT Forest soils potentially store a large pool of carbon and phosphorus. A deep understanding of the total carbon and phosphorus stock in forest soils is vital in the assessment of the nutrients dynamics in forest ecosystems. This study examined the effects of elevation, soil depth, and climatic variables, specifically mean annual temperature (MAT) and mean annual precipitation (MAP), on soil carbon and organic phosphorus in Schrenk's spruce (Picea schrenkiana) forest at Tianshan Mountains. Results showed that soil organic carbon (SOC) significantly increased while organic phosphorus decreased with elevation. Interestingly, carbon increased faster with increasing elevation in the alluvial horizon than in the leached horizon, demonstrating the important role of deep soils in carbon sequestration potential. SOC concentration decreased with soil depth, whereas phosphorus concentration initially decreased and then increased. SOC had no significant relationships with MAT and MAP, whereas phosphorus concentration decreased with MAT. Similar to the impacts of MAT and MAP on SOC, these two climatic variables also exerted no significant influence on C:P ratio.

天山天山天山云杉林土壤沿海拔梯度的碳磷比
摘要森林土壤可能储存大量的碳和磷。深入了解森林土壤中的总碳和磷储量对于评估森林生态系统中的养分动态至关重要。本研究考察了海拔、土壤深度和气候变量,特别是年平均气温(MAT)和年平均降水量(MAP)对天山施伦克云杉林土壤碳和有机磷的影响。结果表明,随着海拔的升高,土壤有机碳含量显著增加,有机磷含量显著降低。有趣的是,随着海拔的增加,冲积层的碳增加速度快于浸出层,这表明深层土壤在碳固存潜力中的重要作用。SOC浓度随土壤深度的增加而降低,而磷浓度则先降低后增加。SOC与MAT和MAP没有显著关系,而磷浓度随MAT而降低。与MAT、MAP对SOC的影响相似,这两个气候变量对C:P比也没有显著影响。
