| Abstract: | An investigation on aquatic organisms was conducted in the upper stream of Heihe River in Qinghai Province,China,in May 2010.There were 39 phytoplankton species belonging to Bacillariophyta,Chlorophyta,Cyanophyta and Cryptophyta,including 25 diatoms,accounting for 64.10% of the total amount;7 green algae,accounting for 17.95%;and 6 blue green algae,account for 15.39%.The amount of the algae was varied from 236 300 ind./L to 1 376 600 ind./L with an average of 913 000 ind./L,while the biomass was arranged from 0.1796 mg/L to 1.0841 mg/L with an average of 0.7306 mg/L.There were 13 species zooplankton,including 5 species protozoan accounting for 38.64%,7 species rotifers accounting for 53.85% and 1 species copepod accounting for 7.69%.The amount of zooplankton was varied from 1.52 ind./L to 11.22 ind./L with an average of 6.06 ind./L,while the biomass was ranged from 0.0076 mg/L to 0.0957 mg/L with an average of 0.0353 mg/L.Four species of fishes were found,among which Schizopygopsis pylzovi Kessler was the new recorded species in this region.The Richness index（D） was found to be 0.5247,Shannon-Wiener index（H） 0.7887,indicating that both the Richness index（D） and Shannon-Wiener index（H） were lower than the biodiversity. |
