Abstract

Abstract: 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 bacteria,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 asignificant increase in the number of microorganisms trend based on the analysis of variance.The number of microorganisms 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 relationship between different soil layer and soil microbe both in Aoxiang and 3 km area.

Key words: fire disturbance, soil bacteria, soil fungi, soil actinomycetes, Daxing′anling
