摘要:
采用野外调查采样及室内实验分析的方法，选取原生植被旱冬瓜林地作为对照，对澜沧江上游山区不同植被类型云南松林、桉树纯林、生态混交林（桤木+圣诞树）土壤细菌、真菌、放线菌3大类微生物的数量及总量进行研究，结果表明：3大类微生物分布均表现为A层大于B层。不同植被类型土壤细菌和真菌数量变化趋势均为旱冬瓜林>生态混交林>桉树林>云南松林，且A、B层消长趋势一致；不同植被类型A层土壤放线菌数量变化趋势为云南松林>桉树林>生态混交林>旱冬瓜林，B层土壤放线菌数量变化趋势则为生态混交林>云南松林>桉树林>旱冬瓜林；不同植被类型土壤微生物总数变化趋势为旱冬瓜林>生态混交林>桉树林>云南松林，A、B层消长趋势一致。
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.
