【 摘 要 】

Several benthic plants and animals live in lakes and reservoirs. Benthic algae, mostly diatoms, can reflect the quality of the water environment. The indicative function of water quality by diatom community and basic principle of diatoms in-dexmethod was described. This paper investigates the benthic algal community in a water reservoir basin.in flood season (July) and non-flood season (November) respectively. A total of 129 species of benthic diatoms were collected in flood season (July) and non-flood season (November). By analyzing the generic index of Trophic Diatom Index (TDI), Index of Biological Diatom (IBD) and Specific Pollution Sensitivity Index (IPS) the status of aquatic ecological environment in this reservoir was evaluated, which indicates that the water quality of reservoir area is better.
