摘　　要：氮素循环是陆地生态系统物质循环的重要组成部分,氮素在土壤中的迁移转化状况既影响着土壤的供氮能力,又与大气、水体的氮素污染紧密相关,因此相关内容一直为国际国内研究的热点。本文在简述土壤氮形态和氮循环各环节概念的基础上,就目前研究的热点和前沿进行了综述,以期能为以后的研究提供一定的思路。Nitrogen cycle is an important part of terrestrial ecosystem in the material cycle. The transfer and transformation of nitrogen in the soil is not only affecting the soil nitrogen supply ability,but also closely related to the nitrogen pollution in atmosphere and water,so the relevant content is always very important all over the world. In this paper,on the basis of introducing soil nitrogen forms and nitrogen cycle,the research focus and research frontiers were summarily reviewed,looking forward to stimulating inspiration for the future explore.
