摘要: 土壤呼吸速率与土壤微生物密切联系。研究了太白山北坡植被土壤微生物对土壤呼吸速率的影响。不同植被类型土壤呼吸速率大小顺序是:阔叶栎林(5.5μmol/(M2.s))>桦木林(4.25μmol/(M2.s))>落叶阔叶林(4.62μmol/(M2.s))>杨树林(3.09μmol/(M2.s))>太白红杉林(1.77μmol/(M2.s))>秦岭冷杉林(1.73μmol/(M2.s))>高山草甸(1.63μmol/(M2.s))。不同植被类型土壤除真菌数量随海拔升高而增多之外,放线菌、细菌都是随海拔升高呈单峰变化趋势。土壤呼吸速率与土壤细菌、放线菌呈极显著正相关性(P<0.01),与真菌则呈极显著负相关(P<0.01),而与海拔梯度呈显著相关(P<0.05),表明土壤呼吸受土壤微生物群落影响较大。

Abstract: Soil respiration is closely related with soil microbe.It has been researched the effect of soil microbe on the soil respiration rate of various vegetations in the northern slope of Taibai Mountain.The results showed that the order of mean soil respiration rate of various vegetations was as following: broad-leaved oak vegetation( 5.5 μmol/( m2·s) )>birch vegetation( 4.25 μmol( m2·s) )>deciduous broad-leaved vegetation( 4.62 μmol/( m2·s) )>poplar vegetation( 3.09 μmol/( m2·s) )>Larix chinensi vegetation( 1.77 μmol/( m2·s) )>Abies chensiensis vegetation( 1.73 μmol/( m2·s) )>alpine meadow( 1.63 μmol/( m2·s) ).With the increase of altitude, the quantity of fungi increased, but the quantity of bacteria and actinomycosis had showed single-peak trend.Soil respiration rate were highly significantly positive to bacterial and actinomycetes( P< 0.01),and soil respiration rate was highly significant negative to fungi( P< 0.01).However altitude was only positive to soil respiration rate.Microbe community had strong effect on soil respiration.

Key words: Soil respiration rate, Bacteria, Actinomycetes, Fungi
