Abstract: 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.

Key words: Soil nitrogen, Nitrogen cycle, Model, Simulation
