Effects of fire disturbance on soil bacterial communities and nitrogen cycling functions in Xingan larch forests in the Daxingan Mountain forest area

Fire is crucial for shaping northern forest ecosystems and can significantly affect the soil microbial community structure. Investigating the effects of fire disturbance on soil microbial diversity and nitrogen cycling is essential to understand the mechanisms underlying soil nitrogen cycling. This study examined the fire burn site of the Xingan larch forest in the Daxingan Mountains, Inner Mongolia, to analyze the impact of varying fire intensities on soil nitrogen, microbial communities, and the abundance of nitrogen cycle related functional genes.
