| 摘 要： | 应用稀释平板法探讨了不同海拔高度土壤细菌、真菌和放线菌数量与生境的关系.结果表明,不同海拔样地真菌数量差异显著；AM-2样地细菌、真菌数量最大；AM-3的放线菌数量最大；而AM-4的细菌数量、真菌数量、放线菌数量均为最小值；相关性分析表明,细菌、真菌、放线菌与海拔、地下生物量呈显著正相关；与土壤含水量呈极显著负相关.这表明,土壤微生物受到地下生物量及土壤含水量影响最大.

| Abstract: | The correlation between soil microbe and habitats in different elevations in Yushu was studied with pour plate method.The results showed that the number of fungi and bacteria were maximal at sampling site AM-2,the number of actinomycete was maximal at sampling site AM-3,the number of bacteria,actinomycete and fungi were minimal at sampling site AM-4.Quantities of soil microbe was positively correlated to altitude and belowground biomass,but negatively correlated to soil moisture content.These findings sugge... |
