摘要

研究了次降雨过程中红壤小流域5种不同土地利用方式土壤N

P养分流失特征。结果表明

在降雨后

花生地、花-橘间作、橘园、板栗园和水田5种利用方式表层土壤N

P养分含量均有不同程度下降

其中花生地N

P含量下降最为明显

水田N

P含量降幅则最小;不同形态养分平均降幅依次为有效氮(5.49%)、有效磷(5.25%)、全氮(1.45%)、全磷(0.59%)。各样地地表径流中水溶态N

P养分含量花生地明显高于其他样地

而泥沙中N

P养分含量则以水田最高;各样地侵蚀泥沙中N

P养分有明显的富集现象

板栗园和橘园N

P养分富集率高于其他样地

水田N

P养分富集率最低。不同形态养分富集率也不同

全氮平均富集率为1.30

有效氮1.18

全磷1.11

有效磷1.38。侵蚀径流中N

P养分与表层土壤相同形态养分之间呈显著正相关。
