以内蒙古自治区根河市潮查林场为研究对象，分别选取2000年和2003年火烧迹地，选取临近未火烧样地作为对照，研究在林火干扰发生距今10年和13年后，在自然恢复后土壤不同层次细菌、真菌、放线菌的数量变化情况。结果表明：火烧13年后火烧迹地的土壤微生物数量比对照样地微生物总体上高，火烧后土壤细菌、真菌、放线菌平均增加了99.8，93.8，100.5万株／g。火烧10年后火烧迹地微生物数量也有明显的增加，土壤细菌、真菌、放线菌的数量分别平均增加了96.2，117.2，105.6万株／g。敖乡和3km 处火烧迹地土壤微生物数量均与土壤深度没有明显的关系。

The sites burnt in 2003 (Aoxiang)and 2000 (3km)in Chaocha State Forest Farm of Genhe city were selected as research area,the unburned forest area was selected as control.The number of soil bacte-ria,fungi and actinomycetes in the natural recovery with different forest fire intensities were investigated which occurred 13 years and 10 years after the fires.The results show that in 13 years after the fire in the burned area,the soil microbial number is higher than that of the control plots.After burning,soil bacteria, fungi,actinomycetes averagely increased by 99.8,93.8 and 100.5 ×104 /g.The results show that asignifi-cant increase in the number of microorganisms trend based on the analysis of variance.The number of mi-croorganisms also increased significantly 10 years Later.The number of bacteria,fungi and actinomycetes increased by 96.2 ×104 /g,117.2 ×104 /g and 105.6 ×104 /g on average.There was no significant rela-tionship between different soil layer and soil microbe both in Aoxiang and 3 km area.
