| 摘 要： | 通过模拟培养试验比较研究了滇池沉积物用细沙原位覆盖后种植苦草、红土原位覆盖后种植苦草以及直接种植苦草三种生态修复措施对无机氮迁移转化的影响.结果表明,直接种植草桶中,水体中高锰酸盐指数、悬浮物质(SS)、NH4+-N及沉积物中NH4+-N的浓度最高,细沙覆盖后种草桶中次之,红土覆盖后种草桶中最低.另外,细沙和红土覆盖后...

| Abstract: | Effects of three ecological restoration measures which are planting Vallisneria spiraslis L.directly in Dianchi sediment,planting Vallisneria spiraslis L.in sediment covered by silver sand and planting Vallisneria spiraslis L.in sediment covered by laterite on transfer and transformation of inorganic nitrogen were studied by indoor incubation experiment.Results showed that the concentrations of CODMn,SS and NH4+-N in waters and NH4+-N in sediment were the highest in plastic casks treated with planting Valli... |
