| 摘 要： | 三期对南明河贵阳市区三江口至水口寺河段12个断面的调查，共获底栖动物31种，其中污染指示种有17种，软体动物在种类上占优势，环节动物在数量上占优势。采用指示生物法、污水生物指数法和生物学指数法(BPI)对河段的水质评价为中污染一重污染，其中中、下游河段污染严重。表明南明河的水质尚差，水质改善亟待加强。

| Abstract: | An investigation on macroinvertebrate community from Sanjiangkou to Shuikousi along the Nanming River in Guiyang was carried out in three times.The authors obtained 31 species of macroinvertebrate in 12 sections,which 17 species of macroinvertebrate are indicator animal of water pollution. Mollusca dominates in species,while annelida dominates in number.At the same time,we adopted the indicator living things,the pollution bio-index and the biological pollution index to evaluate water quality. The investigatied sections were medium-serious contaminated.The middle-lower reaches of the Nanming River were the most serious in polltion.The comprehensive results indicated that the water quality of the Nanming River must be improved. |
