澜沧江上游不同植被类型土壤微生物特征研究
The Study on Soil Microbial Characteristic under Different Types of Vegetation in Upstream of Lancang River
摘要
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 forestPinus yunnanensiseucalyptusAlnus 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.关键词
