水生维管束植物在水污染中的应用

The role of aquatic vascular plants in remediation of water pollution: a review

随着水污染的加剧,高效低耗的水污染处理技术逐渐受到人们的重视,水生维管束植物以其特有的组织和生态功能及易于人工操纵等原因而在净化水体污染、防治富营养化方面发挥了重要的作用。文章对水生维管束植物在水质净化中的作用、影响因素、水生植物的综合利用及其在水污染监测中的作用等方面进行了系统分析,提出多种植物组合比单种植物能更好地实现对水体的净化,通过温度、水深的调控措施可以加强水生维管束植物对水质的净化效果,温度、水深、水质状况以及水生植物的经济价值等是水生植物选择的重要因素。指出了当前水生维管束植物研究中存在的一些问题,认为在人为操纵下,对于水生植物的长效管理是其在水污染应用中的一个重要内容。

with the aggravation of water pollution, much attention has been paid to those highly effective and low consumptive techniques on water pollution remediation. Aquatic vascular plants play an important role in control of water pollution and eutrophication with the characteristics of its specific tissue, ecological functions and easy manipulation. This article summarizes the aspects of aquatic vascular plants on the water purification, it’s influencing factors and the comprehensive utilization as well as their functions in monitoring the water pollution. It is pointed out that the better effect of water purification can be achieved with the combinations of several types of aquatic vascular plants than with only monotype. Regulating the water temperature and depth to a suitable level can strengthen its function of water purification. The water temperature, depth, initial quality and the economic value of aquatic plants are all affecting factors on the selection of aquatic vascular plants. The main aspects and the problems on the research of aquatic vascular plants are discussed. The long-term effective management on the aquatic vascular plants, under manipulation, is believed to be an important part in water pollution control.
