| 摘 要： | 滨海河口区水体盐碱含量高,生态景观萧条,亟需筛选既能耐盐碱又能有效去除氮磷的植物.通过水培实验研究了盐碱胁迫下,芦苇、香蒲的耐受性及对水体中氮、磷的去除率.结果表明,芦苇至少能够耐受10‰的盐度和高达8.5的p H,香蒲能耐受的盐度为7.5‰、p H为8.0,结合生长、生理指标(叶片相对电导率、脯氨酸、叶绿素和根系活力)的变化,芦苇耐盐碱性强于香蒲;盐胁迫下,芦苇对氨氮去除率相对较高,由于香蒲生物量较高,对硝氮、总磷去除效果好,分别比芦苇高2.5%、7.3%,对总氮去除两者相当;碱胁迫下,芦苇耐碱性较强,对氨氮、总磷的去除效果较香蒲稍好,而香蒲对总氮的去除率比芦苇高8.2%.综上所述,芦苇、香蒲可作为修复滨海高盐碱水体生态景观的备选植物.
