| Abstract: | The community structure of phytoplankton was surveyed in five samples collected at five sites at the inlet and outlet,and inner side of the island on the west side in Lang Tso Lake in Xizang(E 87°23′5.46″,N 29°12′33.45″),in July 2017.The results showed that there were 3 phyla and 12 species(genera)of phytoplankton,with density varying from 1.935×104 to 51.558×104 ind/L,average density of 17.188×104 ind/L,and biomass changing from 0.003 mg/L to 0.249 mg/L,average biomass of 0.099 mg/L.Canonical correspondence analysis(CCA)revealed that the phytoplankton in the lake was mainly affected by water temperature,pH,dissolved oxygen level and redox potential.The plankton comprehensive evaluation showed that Lang Tso Lake was a nutrient poor water body,which was in line with the type of plateau lake featured by high altitude,poor water body,high alkalinity and poor phytoplankton biomass.The findings provide basic data for the protection and scientific exploitation of the diversity of aquatic life in the waters,and fill the gap in the study of the structure of plankton communities in Lang Tso Lake in Xizang. |
