沉水植物苦草属在水体环境修复中的研究进展和应用现状

Research Advances and Application Situation of Vallisneria in Water Environmental Restoration

为掌握具水生态修复功能的沉水植物苦草属的研究现状,综述了国内外近30年关于该属植物的生物学特性,与各类环境因子之间的相互作用,以及在工程中的具体应用等方面的内容。已有研究结果表明,有序地种植苦草属植物,并与其他水生植物进行合理搭配,既形成优美的景观,又具有十分重要的生态修复意义。同时,为使苦草属植物发挥良好的生态恢复效益,指出现有研究中尚存在的问题,并提出今后的3个研究重点:(1)加大教育宣传,扩大应用范围;(2)规范种植管养,开发实用工具;(3)提倡资源化利用,实现持续发展。

The paper aims to summarize the research status of the genus Vallisneria, which has high value inwater ecological restoration. By means of reviewing nearly 30 years relevant researches on Vallisneriabiological characteristics, the interaction with environmental factors and the application situation inengineering etc., it was considered that cultivating the species of Vallisneria methodically with other aquaticplants could benefit the landscape construction, and could also be useful for water ecological restoration.Meanwhile, existing problems in researches on this genus were pointed out in this paper. To achievingecological restoration benefits, three issues were proposed for further study：（1） strengthening publicity andenlarging application;（2） standardizing plant maintenance and developing practical tools;（3） utilizingresources rationally and attaining sustainable development.
