By imitating different concentration of Cd2+ Cu2+ Cr3+ Cr6+and Zn2+polluted water environment,we mainly studied their toxic effects on aquatic piants by means of measurement of physiologicai indexes and electron microscopy observation as well as the relieving to Cu2+ injury of antioxidase enzyme system in Lemna minor L. and Vallisneria asiatica Miki in this paper by throwing Ce.the experimental results showed that Cd2+ Cu2+ Cr3+ Cr6+ and Zn2+ might injure photosynthetic systems, protective enzyme system, substance metabolism systems and cell ultrastructure of the plant.

本文通过模拟不同浓度梯度的重金属Cd~(2+)、Cu~(2+)、Cr~(3+)、Cr~(6+)和Zn~(2+)污染环境，利用生理生化测定、扫描电镜、透射电镜、气相色谱及激光共聚焦等实验手段，研究了四种金属离子对不同生态型的水生植物的毒害影响，初步探索了Ce对浮萍Cu害的缓解效应和La、Zn及其交互作用对浮萍活性氧清除系统影响。

The khondalite series within Kongling Group in Yichang City, Hubei Province are composed of aluminum-rich schists-gneisses and garnet-sillimanite-quartzites, leptynite and mafic granulites, its protoliths are clay, sandstones-greywacke and marlite. REE distribution patterns of aluminum-rich gneisses incline NASC, Eu show negative abnormity and Ce displays no abnormity in chondrite-normalized REE distribution patterns.
