Characteristics of nitrogen mineralization in soils under different forest types in cold-temperate forest region

  • 摘要: 目的研究不同林型不同海拔下森林土壤凋落物层和表层矿质土壤中氮矿化特征及与培养时间、土壤理化性质的关系,以了解森林土壤中针阔叶林下氮的矿化潜能,为充分地理解森林土壤氮循环提供参考。方法采用实验室好气培养法,以我国寒温带林区大兴安岭的偃松林、杜鹃−白桦林、杜鹃−落叶松林、杜香−落叶松林下漂灰土和棕色针叶林土的凋落物层及表层矿质土壤为研究对象,按培养时间测定其中的铵态氮、硝态氮含量及全氮、有机质、有机碳、含水量、pH、土壤机械组成等理化性质,研究4种林型下土壤中氮矿化与培养时间、海拔的关系,并通过主成分分析探讨氮矿化的潜在驱动因素。结果4种林型下,凋落物层中氮矿化以氨化作用占优势,表层矿质土壤中以硝化作用占优势。随培养时间的延长,凋落物层的矿化氮含量呈现先增后减的趋势,而表层矿质土壤中矿化氮含量呈现先减后增的趋势,培养初期有明显的矿化滞后期。pH对表层矿质土壤氮矿化产生了直接影响,而有机质、有机碳、全氮、土壤机械组成是土壤氮矿化过程中潜在的主要驱动因子。结论寒温带林区不同林型下凋落物层和表层矿质土壤中的氮矿化特征,因培养时间的差异导致氮矿化的趋势差异,两个层次均表现为随着海拔的升高,氮矿化量减少。通过比较分析,能够深入地认识寒温带林区森林土壤氮矿化潜力的变化趋势,研究结果为进一步理解森林土壤氮循环提供科学依据。
