Abstract

We developed a new biotic index of species pollution value (SPV) and community pollution value (CPV) based on the correlation of protozoan communities with chemical water quality to assess freshwater pollution. Five hundred and twenty-three species of protozoa SPV were established based on the data of River Hangjiang and Lake Donghu. The present research was conducted in order to further consummate the biotic index. Protozoa of the water system in Changde City were collected from 16 stations using the PFU method and the water chemical parameters of the stations were analyzed. The results showed that CPV calculated from SPV had a close correlation with the degree of water pollution (p < 0.00001), which indicated that the method is reliable. By combining the data of River Hangjiang, Lake Donghu and Changde City, the final form of SPV was accomplished and the SPV list increased to 757. The ultimate water standard evaluated by CPV calculated from SPV was proposed.

摘要

我们基于原生动物群落与化学水质的相关性，开发了一种新的生物指数，即物种污染值（SPV）和群落污染值（CPV），以评估淡水污染。根据汉江和东湖的数据，建立了523种原生动物的SPV。本研究旨在进一步完善该生物指数。采用聚氨酯泡沫塑料块（PFU）法从常德市水系的16个站点采集原生动物，并分析了各站点的水化学参数。结果表明，由SPV计算得出的CPV与水污染程度密切相关（p < 0.00001），这表明该方法是可靠的。通过结合汉江、东湖和常德市的数据，完成了SPV的最终形式，SPV列表增加到757种。提出了由SPV计算得出的CPV评估的最终水质标准。
