摘　　要：N既是植物必需的营养元素,又是造成环境污染的重要元素.正确模拟土壤中N循环已经成为科学家共同关注的热点问题.简述了土壤N循环的基本过程,重点介绍了13种土壤N循环模型和6个土壤N循环过程的模拟,并讨论了模拟中存在的参数化问题.Nitrogen is one of the necessary nutrients for plant, and also a primary element leading to environmental pollution. Many researches have been concerned about the contribution of agricultural activities to environmental pollution by nitrogenous compounds, and the focus is how to simulate soil nitrogen cycling processes correctly. In this paper, the primary soil nitrogen cycling processes were reviewed in brief, with 13 cycling models and 6 simulated cycling processes introduced, and the parameterization of models discussed.
