, 1999 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 ...

, 2015 反硝化作用作为水体彻底去除硝态氮的主要途径之一,主要发生在沉积物中。为了调查杭州西湖高硝态氮水体中底泥反硝化作用及其影响因子,2013年12月(冬季)和2014年6月(夏季)在西湖5个子湖区和3个湖湾的13个点位(X1~X13)进行样品采集,以底泥中硝酸盐还原酶活性和反硝化强度代表反硝化作用。结果表明,西湖水体冬夏两季TN浓度分别为1.568~2.613 mg/L和1.117~2.848 mg/L,硝态氮在TN中占比平均值分别为76%和72%。冬夏两季的底泥反硝化强度分别为0.132~1.350 mg ...

, 2003 研究黄土旱塬区长期定位试验中 1 0个典型处理土壤剖面 (0～ 30 0 cm)水分和无机氮的季节变化 ,探讨在半干旱区农田无机氮的积累与迁移机理。结果表明休闲处理除表层外土壤剖面的水分、硝态氮和铵态氮的含量分别稳定在 1 7%～ 2 0 %、4～ 7mg N/kg和 6～ 1 0 mg N/kg土的范围。种植作物显著地改变土壤剖面水分和硝态氮的分布状况 ,并使其含量发生大幅度的季节变化。作物利用限制了农田土壤硝态氮向深层的迁移。小麦连作无化肥氮处理及苜蓿连作不施肥或氮 ...
