| 摘 要： | 为了进一步探讨土壤凋落物层对土壤呼吸的影响,用Li-6400对大兴安岭北部3种林型(白桦-落叶松林、樟子松-落叶松林和落叶松纯林)自然状态的土壤呼吸(RS)、去凋落物后的土壤呼吸(RD)以及凋落物呼吸(RL)进行测定,结果表明:凋落物层的去除会使土壤呼吸速率降低,3种林型观测期内平均RS分别为7.32μmol m-2 s-1、8.55μmol m-2 s-1和6.66μmol m-2 s-1,平均RD分别为6.46μmol m-2 s-1、7.98μmol m-2 s-1和5.74μmol m-2 s-1。但去除凋落物后的土壤总呼吸速率较自然状态下分别升高了13.85%、16.21%和13.73%;凋落物的去除并不影响...
