Relationship between elements in the absorption and purification(富营养化水体中植物的元素吸收与净化能力的关系)
研究了不同植物在两种程度富营养化水中对元素的去除率及对富营养化成分的去除率.在重度富营养化水中,蒸腾强度高的植物对水中各成分均具较好的净化效果;而在轻度富营养化水中,所研究的植物间没有共同趋势.另外,可根据不同植物对环境的各自适应方式将其用于净化不同类型的污水.其中,灯芯草和空心菜不需元素补给,在重度和轻度富营养化水中均具较好的净化能力;鸭跖草是耐阴植物,有适度遮荫时净化效果较好;菩提子用于净化重度富营养化水时需补给适量的常量营养元素;芦苇在轻度富营养化水中净化能力较好,也适合用于盐离子浓度高的重度富营养化水净化;萱草和石菖蒲在两种水中净化效果接近,但不如上述植物,其优势是能越冬生长....
