摘　　要：氮循环是地球生态系统中最重要的生物地球化学循环之一,它在土壤科学中扮演着关键角色。微生物等的作用使得大气中的氮进入土壤,并以氨、硝酸盐等形式被动植物吸收,最后在微生物的作用下再次回到大气中,形成了一个循环。氮循环可以增强土壤的肥力,不仅可以促进自然环境中的植物生长,还能增加农田作物产量,对维持土壤健康、农业生产和环境保护具有深远的影响。本文综述了土壤中氮循环的基本过程,并对土壤中氮循环当代农业生产的关系、影响土壤中氮循环的主要因素进行了详细分析论述,为合理利用和维护土壤中氮循环,实现可持续农业和保护自然环境提供理论支持。Nitrogen Cycle is one of the most significant biogeochemical cycles,which plays a key role in soil science.The nitrogen in air enters into soil by the effect of microorganism and transforms as ammonia and nitrate or other forms to be absorbed by plants,and it returns to air through microorganism to complete a cycle.The cycle can improve the soil fertility,which not only promote the growth of plant,but also increase the crop productivity.Furthermore,it is of great influence to maintain healthy soil and agricultural productivity,and protect environment.This paper summarized the basic process of nitrogen cycle,and analyzed the relationship between the cycle and modern agricultural production as well as the factors that impacts the whole cycle in soil.It would provide the theory support for achieving sustainable agriculture and natural environment protection when utilizing and maintaining the nitrogen cycle in soil.
