| 摘 要： | 环境中氮污染对人类生活和生产影响很大。该文研究了氮肥在SPAC系统的分布情况及氮素平衡问题，建立了氮肥在SPAC系统的综合数学模型。该模型为排水条件下减少氮肥流失措施提供一定的依据，可有效提高氮肥利用率并减少其对环境的影响，尤其是减少其对水环境的污染。

| Abstract: | The nitrogenous pollution is a environmental problem which has prodigious influence on our life and production.It has become one of the leading study topics facing scholars in the world. According to the available data, this paper studies the nitrogenous fertilizer distribution in SPAC(Soil-Plant-Atmosphere Continuum) system and the nitrogen balance,and the synthetical mathematical model of nitrogen in SPAC system was built. According to the model, it can provide the measures of reducing nitrogenous fertilizer losses. It can increase the utilizable proportion of nitrogenous fertilizers effectively and reduce the effect on environment, especially on the water environment. |
