摘要
对邛海浮游植物的种类组成、生物量、优势种、污染指示种和硅藻指数等指标的分析表明,邛海浮游植物的污染指标种占40.4%,优势种多为β-中污带指示种,水质评价为β-中污染,浮游植物生物量碳重量为230mg/m ̄3,硅藻指数为142.4,表明水体处于中营养水平。
The water pollution and eutrophication of the Qionghai Lake was
evaluated.based on the analysis of the species composition,biomass,dominant
species,saprobic indi-cator,diatom biotic index of the phytoplankton sampled from 5 stations in
l993;The avex-age biomass of the phytoplankton was 230 mg C/L.In 99 species found,the
saprobic indicator up 40.4%.Bacillariophyta and Chlorophyta were the main groups of the
phytoplankton.Most of the saprobic indicator are the indicator of the β-ms,the average diatom
biotieindex was l42.4.It was judged that the water pollution of the Qionghai Lake was β-mand
in moderate tropic level.
