【摘要】 根据国家标准《水质——微型生物群落监测——PFU法》(GB/T12990 -91),两次对湖北鸭儿湖生物氧化塘进行了生物监测与评价.共检出原生动物192种,其中植鞭毛虫48种、动鞭毛虫46种、纤毛虫82种、肉足虫16种.试验所得生物学参数,即PFU原生动物群落结构和功能参数表明:如今Ⅰ号氧化塘整体状况与1982年相比变化较大,Ⅱ号氧化塘相比1982年也有所变化,但不是很大.其它3个氧化塘,第一次试验结果为从Ⅲ号氧化塘到Ⅴ号氧化塘依次变好;第二次试验结果则按Ⅴ、Ⅲ、Ⅳ顺序变好.两次试验所得此三塘的生物学参数之间差别并不大.鸭儿湖氧化塘水体状况与1982年所得结果相比有了很大改善. 图5表3参13更多还原

【Abstract】 Biomonitoring and evaluation were performed for abandoned oxidation ponds in the Ya-Er Lake, based on the National Standard of PRC "Water Quality-Microbial Community Biomonitoring PFU Method". During this investigation, altogether 192 species of protozoa were identified and recorded, including 48 phytomastigophora species, 46 zoomastigophora species, 82 ciliata species and 16 sarcodina species. The biological parameters, that is, the structural and functional parameters of PFU protozoan community, resulted from this study demonstrated that the first oxidation pond at present changed greatly compared with that in 1982 and the second oxidation pond changed too, but not as much as the first pond. The other three ponds became better in the following sequence: pond III, pond Ⅳ, pond Ⅴ during the first study, and the sequence: pond Ⅴ, pond III, pond Ⅳ during the second study. But the differences among the three ponds were not significant. The comparison of the results from the present study and that in 1982 demonstrated that the water quality and aquatic ecology became better after the oxidation ponds were abandoned.
