中文摘要：

水体富营养化及其引起的有害藻类水华是重要的环境问题,严重威胁着水体景观、生态功能以及人类健康.如何有效防治水华是目前环境领域的研究热点和前沿.通过植物的化感作用来抑制藻类生长作为一种新型的生物抑藻技术而备受关注.而从水生植物中提取、分离出的化感物质更是对控制水华爆发具有专一、高效的特点.综述了从自然环境里较易获得的芦苇中得到的化感物质EMA对常见水华和赤潮藻类的影响,对抑藻效果和抑制机理进行了分析阐述,并提出了目前仍存在的问题和该领域内的发展前景.

英文摘要：

Eutrophication and harmful algal blooms are one of the major environmental problems in China and the countries of the world, and undertaking a serious threat to water landscape, ecological function and human health. How to effectively treat with HABs is currently the hot field of the environment and cuttingedge research. By allelopathic plants to inhibit the growth of algae is a new biological algal technol ogy has been receiving world wide attention. Extracted and isolated from aquatic plants which is allelo chemicals for controlling water blooms have the characteristics of loyal and efficient. In this paper, influ ences of reeds allelochemicals EMA from the natural environment to get easier to obtain on common domi nant species are concluded, analysis of the algal effects and inhibition mechanism, and propose the existing problems and development prospects.
