摘要： 水生植物按挺水、浮水、沉水植物分成3类,分别列举出常见的具有化感抑藻作用的水生植物及其抑制藻类摘。总要结出化感物质抑藻具有选择性、低促高抑等特点,同时不同化感物质之间还存在协同、相加和拮抗作用,并从光合系统、细胞膜、酶活性等细胞水平和基因水平出发介绍了水生植物化感抑藻的作用机制。针对水生植物日常代谢的化感物质浓度较低以及实验室效果能否较好地应用于工程项目,今后的研究重点将是具有高效抑藻作用的化感物质的人工提取或合成,及其在自然水体中的实际应用研究。

Abstract: The species of common allelopathic algae-inhibiting emergent, floating and submerged plants and the algal suppressed were listed. It was concluded that allelochemicals had the characteristics of selectivity and promotion low concentration, inhibition at highconcentration, and there were synergistic, additive and antagonistic effects among different allelochemicals. And the mechanism of al-gae inhibition by allelopathy was introduced from the cell level ( such as photosynthetic system, cell membrane and enzyme activity)and gene level. Aquatic plants had a low concentration of allelochemicals in their daily metabolism and wheth the laboratory effect couldbe well applied to engineering projects, it was pointed out that the future research focus will be on the artificial synthesis of highly effec-tive allelochemicals and their practical applications in natural conditions.

Key words: aquatic plants, allelopathy, allelochemicals, antialgal mechanism, cell level
