摘要: 土壤氮素矿化是反映土壤供氮能力的重要因素之一,也是目前国内外土壤生态学研究热点之一。土壤氮素矿化可表示为土壤有机氮的含量、矿化过程中土壤环境因素和矿化持续时间的复合函数;土壤氮素矿化的基本模型有3类,即动力学模型、热力学模型及经验模型;影响矿化过程并可定量表示的土壤环境条件如土壤温度、湿度、pH及有机质形态。

关键词: 土壤有机氮, 矿化, 模型

Abstract: The mineralization of soil organic nitrogen is one of the most important factors reflecting soil nitrogen-supply capability and one of the hot subjects of soil ecology in home and abroad, which could be referred as a function of soil organic content, duration of its mineralization, and soil environmental factors affecting the process of mineralization. There are three basic model types of soil nitrogen mineralization, namely, the kinetic, thermodynamic and empirical types. Soil temperature, moisture, pH and organic N forms are the soil environmental elements which impact the mineralization process and could be quantified.

Key words: Soil organic nitrogen, Mineralization, Model
