摘要: 沉水植物对重金属的积累净化和受害机理研究主要集中在4个方面: (1)沉水植物对重金属(包括放射性物质)的吸收、积累和净化作用; (2)沉水植物对重金属的抗性强弱和机制; (3)沉水植物用于监测水体的重金属污染; (4)沉水植物的重金属胁迫机制, 包括重金属对植物形态和显微结构的损伤, 对植物抗氧化酶系统的影响, 对植物的叶绿素、蛋白质以及光合与呼吸作用等生理生化指标的影响, 植物对重金属的吸附和转运动力学, 以及Zn对Cd毒害的拮抗等。

Abstract: The author reviewed the absorption and purification of heavy metals by submerged macrophytes and the mechanism of harm. Four aspects were summarized and analyzed: (1) absorption and purification of heavy metals by submerged macrophytes;(2) resistance of submerged macrophytes to the stress of heavy metals and the mechanism; (3) monitoring the polluted water by heavy metals with submerged macrophytes; and (4) the stress of heavy metal contamination and its mechanism in submerged macrophytes.
