摘要
2006年4月对马岭河浮游植物进行调查研究。经定性,定量分析共纪录浮游植物130种(其中包括变种和变型),隶属4门7纲13目22科39属,其中硅藻在种类及数量上均占优势。通过浮游植物数量、群落结构、硅藻商、Margalef指数、Shannon-Weiner指数和Pielou均匀度指数对该地区进行了富营养状况评价。结果表明:马岭河受到中偏重污染,属于富营养型水体。
The phytoplankton in the Malinghe River was preliminarily investigated in this paper in April 2006. By means of identification, the results showed that there were 130 species , varieties and forms, belonging to 39 genera, 22 families, 13 orders,7classes and 4 divisions. Bacillariophyta was dominant in species and quantity. Results based on phytoplankton quantity , structure and three diversity indices revealed that the Malinghe River had been polluted in a moderate way and became eutrophic.
