采用PFU法对常德市16个水系站位的原生动物进行了采样。每年进行采样程序，在不同的网站在水系统和488种原生动物的季节性频率进行了鉴定。同时，对这些站点的水样进行了采样，并分析了各种水化学参数，包括DO、COD、BOD5、NH3、TP和挥发酚。本研究的目的是一方面利用化学方法对常德市的水污染状况进行调查，另一方面利用原生动物对水质进行评价。根据水化学参数和原生动物数据，推导出研究区的生物指数。建立了469种原生动物的物种污染值（SPV），并将SPV计算出的群落污染值（CPV）用于水质评价。对生物指数法进行了检验，结果表明，由SPV计算的CPV值与水体污染程度密切相关（p<0.00001）。这说明生物指数法是可靠的。提出了用CPV划分水质等级的建议。
Protozoan were collected from 16 stations in water system of Changde City (China) using the PFU method. Sampling programs were conduced on a yearly basis, with seasonal frequency at diverse sites in the water system and 488 species of protozoa was identified. At the same time, Water sampling from these stations was conducted and various water chemical parameters, including DO, COD, BOD5, NH3, TP, and Volatile Phenol, were analyzed. The aim of the research was, on one hand, using chemical method to take an investigation to the water pollution status of Changde City; on the other hand, using protozoan to make an evaluation to the water quality. With the chemical water parameters and protozoa data, a biotic index was derived for the investigated region. The species pollution value (SPV) of 469 protozoa species was established, and the community pollution value (CPV) calculated from SPV was used to evaluate water quality. The method of the biotic index was tested and the result showed that CPV calculated from SPV had a close correlation with the degree of water pollution (p<0.00001). This indicated that the method of the biotic index is reliable. The water quality degrees divided by CPV were suggested.
