黟县宏村水系浮游植物调查与水质评价

Phytoplankton investigation and water quality evaluation in Hongcun hydraulic engineering of Yixian

2002年9月至2004年4月对黟县宏村水系进行四季调查,共采集到浮游植物122属种。依据调查结果选用“污染指示种”、“指示群落”两种方法对宏村水系水质污染状况进行了评价。研究表明,宏村水系属微污———甲型中污水体。

The community compoition of phytoplankton was investigated in Hongcun hydraulic engineering in the period September 2002,January and,July 2003,April 2004.The total of 72 genera were collected including 38 genera of Chlorophyta,21 genera of Bacillariophyta,5 genera of Euglenophyta,2 genera of Pyrrophyta and 1genera of Chrysophyta. On the basis of the investigation of the phytoplankton,a biological assessment of water pollution was conducted by using the methods of “saprobie indicator”,“indicator commuuity”.The trophic type of Hongcun hydraulic engineering could be regarded as oligotrophic to mesotrophic.
