| 摘 要： | 研究阳际峰自然保护区不同海拔梯度土壤剖面状况及其微生物学性状,探讨土壤微生物量C与N、酶活性、微生物商与呼吸速率的变化及其相互关系。结果发现,不同海拔梯度土壤在微生物学性状上均有较大差异。总的趋势是植被覆盖度高,地形平缓,土层厚,微生物活性强,且与海拔梯度呈显著正相关。在剖面分布上,也有明显的层次差异,即随土层的增加而减少。

| Abstract: | The soil profile and soil vertical pattern of the Yngjifeng Moutain Nature Reserve were surveyed,the soil microbial biomass C,N(SMBC,SMBN),soil respiration(C-CO2),microbial quotient(Cmic/TOC),metabolic quotient(qCO2) and enzyme activities were studied.There was obvious difference in microbial properties along the elevation gradient.The enzyme activities were strong in the plot with good vegetation coverage,flat terrain,and thick soil layer.There was significant difference(p<0.05) between the altitude and the microbial biomass and enzyme activities in the surface layer(A).In profile,the biological activities decreased with the increase of the depth of the layers of soil. |
