| 摘 要： | 以北方半干旱地区典型内陆封闭湖泊岱海为研究对象,采用室内模拟实验方法,开展了温度、pH、溶解氧及水生植物对湖泊沉积物中NH+4-N释放的影响研究.结果表明,温度升高,中性条件,厌氧条件均有利于NH+4-N的释放.狐尾藻对上覆水NH+4-N含量的有效控制作用是其抑制底泥释放、同化吸收作用和增强上覆水氧化条件等综合作用的结果,植物修复是控制湖泊富营养化水平的有效措施.

| Abstract: | The Daihai Lake is a typical inland lake in a semiarid region in Inner Mongolia,China.This research is mainly focus on the impact of temperature,pH values,dissolved oxygen,and hydrophyte(take Myriophyllum spicatum L.for example)on ammonium nitrogen release from the surface sediments of the Daihai Lake.The result indicated that higher temperature,neutral condition and anaerobic condition would improve the release of ammonium nitrogen.Furthermore,assimilation of Myriophyllum spicatum L.on the ammonium nitroge... |
