1黄河口湿地典型盐碱植被群落土壤氮素的季节动态及根际效应显示文摘于5、8和10月对黄河口湿地典型断面盐碱植被群落进行3个航次的野外生态调查,研究了不同植被覆盖的湿地土壤氮素的时空分布特征及典型盐碱植物碱蓬和芦苇群落土壤氮素的根际效应,并基于线性模型的冗余分析(RDA)探讨土壤理化参数对氮素分布特征的影响.结果表明,黄河口湿地5月和10月土壤氮素含量高于8月,土壤氮素以有机氮为主,无机氮以铵态氮为主;总体上,表层土壤氮素含量芦苇>碱蓬>光滩,光滩土壤氮素含量低于碱蓬和芦苇群落土壤的30%—50%;光滩、碱蓬和芦苇群落剖面土壤总氮、有机氮和铵态氮在0—10 cm表层含量最高,随土壤深度其含量下降,硝态氮在土壤中呈现显著淋溶作用,其峰值出现在地下土壤层30 cm左右;碱蓬和芦苇群落根际土壤氮素含量均高于非根际土壤,且碱蓬根际土壤氮素含量显著高于芦苇根际土壤(P<0.05).RDA分析结果表明,影响土壤氮素分布特征的主要理化参数是土壤有机碳含量和pH.植被种类影响黄河口湿地土壤氮素的累积,一般情况下土壤氮素的累积量呈现芦苇>碱蓬>光滩的特征,并具有明显的季节差异,相对芦苇群落,碱蓬在生长季节8月份根际土壤中积累更多的氮素.梁坤 樊玉清 Kudakwashe Meki 敦萌 闫琴 郑浩 李锋民 罗先香 2019环境化学2019,38,10:6
