为探索火对白桦落叶松林土壤微生物的干扰作用，采用试验点烧方法调查分析了火后土壤微生物群落的即时变化。结果表明：火干扰减少了土壤微生物量，细菌、放线菌、真菌含量，同时降低了火后土壤微生物的代谢能力、土壤Shannon－wiener多样性指数、群落均匀度；燃烧过程中的平均温度与细菌、放线菌含量，微生物量碳质量分数的相对变化率显著相关，说明细菌、放线菌含量，微生物量碳质量分数的变化受平均温度的影响；最高温度与细菌、真菌、放线菌含量，微生物量碳质量分数，平均吸光率显著相关。

We burned the experimental place to explore the impact of fire on the soil microbe of white birch and larch forest .The fire not only reduced soil microbial biomass carbon, bacteria, actinomyces and fungi, but also decreased microbial meta-bolic capacity, Shannon-wiener diversity index, and community evenness in the soil.In the process of burning, the change of bacteria,actinomyces , microbial biomass carbon were influenced by the average temperature.The highest temperature correlated significantly with the bacteria, fungi, actinomycetes, microbial biomass carbon and the average absorbance.
