太湖流域水生生物水质基准推导的物种选择

水生生物水质基准是水质基准体系的重要组成部分。由于不同地区的生态体系存在差异,所需要推导的水质基准也存在不同。目前太湖流域的水质基准研究刚刚起步,国内外制订的水质标准并不能代表太湖流域的水生生物和环境特征。因此,开展基于太湖流域的水生生物和环境特征的水质基准研究,对于太湖流域的水环境保护和水质管理具有重要的作用和意义。在水生生物水质基准的物种选择方面,选择了两种鱼类、两种浮游动物、3种底栖动物以及一种水生植物或浮游藻类,可以全面的代表太湖流域的水生态结构和营养等级。

Species Selection Derived from the Water Quality Criteria Based on Hydrobios in the Taihu Lake Basin

Aquatic water quality criteria are an important part of the water quality benchmarking system.As the ecological systems vary in different regions, the water quality benchmarks needed to be derived are also different. At present, study of the water quality criteria of the Taihu Lake Basin is just in a beginning stage and those formulated home and abroad cannot properly represent the aquatic life and environment characteristics of the Taihu Lake Basin. Therefore, studying the water quality criteria based on the aquatic organisms and environmental characteristics of the Taihu Lake Basin is of great significance to the water environment protection and water quality management in the Taihu Lake Basin. With regard to the selection of species on the basis of aquatic water criteria, two species of fish, two kinds of zooplankton, three species of benthic fauna and one aquatic plant or phytoplankton are chosen, overall representing the aquatic ecological structure and nutrition level of the Taihu Lake Basin.
