| 摘 要： | 应用凤眼莲生态系统治理了上海市区一条富营养化河浜,使水质改善,由于藻类生长受到控制而水变澄清。凤眼莲抑制藻类生长的作用机制除了对光和矿质营养的竞争外,主要是由于凤眼莲根系向水体分泌化合物,能伤害和清除藻类(剋制作用Allelopaihic effect)。根圈栖生的一种软体动物——水蜗牛,以藻类为食,也是凤眼莲生态系统清除藻类的一个因素。

| Abstract: | An eutrophic canal in the urban area of Shanghai has been harnessed by means of establishing a new ecosystem including water-hyacinth (Eichho-rnia crassipes). In addition to the competition of water-hyacinth with algae for light and mineral nutrients, the excretion from root system of water-hyacinth can injure and abate algal cells and Hippeutis sp. (Planorbidae), a kind of mollusca living in the root zone of water-hyacinth, is feeding on algae. |
