摘要

珠江支流谷河表观上可定义为城市黑臭水体。轮虫作为重要的指示生物，在评价水体营养和污染状态等方面得到广泛应用，但轮虫与黑臭水体关系的研究基本为空白。于2017年11月至2018年3月对广州谷河中大河段进行了轮虫与水体黑臭的3次调研。通过轮虫污染指示性种类组成、

E/O

指数、

B/T

指数和香农多样性指数

(H′)

对水质进行富营养化评价，采用黑臭多因子加权指数法(

)对谷河进行黑臭评价。结果表明，谷河中大河段的轮虫共计35种，隶属10科16属，其中污染指示种23种。根据

E/O

指数和

B/T

指数均判定谷河达到富营养化水平。

H′

指数判定谷河为α-中污型和β-中污型。Pearson相关性分析表明轮虫种类数、丰度与水温、COD

、DO、Chl

呈显著相关(

﹤0.05)。典范对应分析显示，藻类丰度、Chl

、水温、COD

等是影响谷河群落结构变化的重要因素，前翼轮虫、晶囊轮虫与

呈相关性显著，可作为谷河水体污染加重的指示生物。但轮虫总丰度、臂尾轮虫总丰度、臂尾轮虫组成比例与

没有显著相关性。研究表明轮虫可作为有效的水体污染指示生物来评价谷河水体营养状况，但用来评价水体黑臭状况还有待后续的深入研究。

Abstract

Gu River

a tributary of the Pearl River can be defined as urban black-odor water bodies. As important indicator organisms

rotifers have been widely used in the evaluation of water body nutrition and pollution status

but the research on the relationship between rotifers community structure and black-odor water body is limited. Three surveys of rotifers and black-odor water bodies were investigated in the part of Gu River along the campus of Sun Yat-sen University in Guangzhou from November 2017 to March 2018. The eutrophication of water quality was evaluated by composition of pollution indicative species of rotifer

index and Shannon-ack odorous water in Gu River. The black-odor indexes with parameters of multifactor (

) were used to evaluate the situation of black odorous water in the Gu River. The results showed that there were a total of 35 species of rotifera in the part of Gu River along the campus of Sun Yat-sen University

belonging to 10 families and 16 genera

among which 23 species are pollution indicator. Both

index and

but further studies are needed for the use of rotifers for black-odor evaluation.
