鸭绿江中下游、辽河、大凌河流域浮游植物比较研究
|
Abstract:
2010年5~6月，通过对辽西北供水工程供水区(鸭绿江中下游)和受水区(辽河、大凌河)流域浮游植物种类区系组成、现存量及分布等内容的调查研究，共鉴定出浮游植物8门，91属，241种。综合评价：供水区水域呈贫-中营养型，水质受轻微污染；受水区水域呈中-富营养型，水质受中度污染，部分区域富营养化较严重。
The current species composition, standing crop and distribution, ect. on the phytoplankton were investigated and studied in the waters of the Northwest of Liaoning Province water supply project, during May to June in 2010. The water supply project consists of the water supply (the middle and lower reaches of Yalu River) and water benefited areas (Liaohe and Dalinghe River). There were 241 species of phytoplankton, which belonged to 91 genera of 8 phyla. The overall evaluation suggested that the water supply area could be delimited to os-β-ms level and the water was polluted slightly. However, the water benefited area could be delimited to β-α-ms level; the water was medium-polluted; and the eutrophication was more serious in some regional water.
