土壤生态系统的稳定对维持森林生态平衡具有重要意义,而森林土壤微生物是影响森林生态系统的重要因素。由于人类行为造成的土壤氮素增加会对森林土壤微生物产生巨大影响,氮添加可使森林土壤碳氮含量显著增加,并通过氮素对土壤环境和土壤微生物的影响,改变土壤微生物群落结构、多样性和功能。因此,阅读和整理国内外关于氮添加影响土壤性质以及土壤微生物变化的大量文献,探究氮添加对土壤碳氮转化、微生物群落结构和多样性、功能群的响应机理等方面的影响具有重要意义。
The stability of soil ecosystem is of great significance for maintaining forest ecological balance, and forest soil microorganisms are important factors affecting forest ecosystem. The increase in soil nitrogen caused by human behavior will have a great impact on forest soil microorganisms. Nitrogen addition can significantly increase the carbon and nitrogen content of forest soil, and change the structure, diversity and function of soil microbial community through the influence of nitrogen on soil environment and soil microorganisms. Therefore, it is of great significance to read and sort out a large number of domestic and foreign literature on the effects of nitrogen addition on soil properties and soil microbial changes, and to explore the effects of nitrogen addition on soil carbon and nitrogen transformation, microbial community structure and diversity, and response mechanism of functional groups.
