Abstract:: With the Alnus nepalensis forest as control, to investigate the quantity of soil microbe (bacteria, epiphyte and actinomyces) and microbial biomass of different vegetation types in upstream of Lancang River by the method of field sampling and laboratory analysis. The others vegetation types are Pinus yunnanensis, eucalyptus and eco-mixed forest (Alnus nepalensis+Acacia dealbata). The results indicated that the A layer of the quantity of bacteria, epiphyte and actinomyces were higher than the B layer. The order of the A layer the quantity of bacterial and epiphyte were Alnus nepalensis forest>eco-mixed forest>eucalyptus>Pinus yunnanensis. The B layer is same as the A layer. In the A layer, the order of the quantity of actinomyces was Pinus yunnanensis>eucalyptus>eco-mixed forest>Alnus nepalensis forest. In the B layer, the order of the quantity of actinomyces was eco-mixed forest>Pinus yunnanensis>eucalyptus>Alnus nepalensis forest. In the A layer, the order of soil microbial biomass is Alnus nepalensis fores>eco-mixed forest>eucalyptus>Pinus yunnanensis. The order in B layer is same as that in A layer.
