摘要

In spring,summer,autumn 2015,we studied the seasonal variation of phytoplankton community structure in six rivers within Duobukuer Nature Reserve,and made preliminary evaluation of the water quality in Duobukuer Nature Reserve based on phytoplankton diversity.The results showed that a total of 7 phyla,41 genera,66 species and varieties of phytoplankton were identified in Duobukuer Nature Reserve;the annual species composition was dominated by diatom( 59%) which also preponderated in dominant species( 84. 3%),biomass( 68%)and abundance( 75%),with no significant seasonal variation. Shannon-Wiener diversity index( H’) and Pielou evenness index( J) were used to evaluate the water quality in 13 sampling points,and the results showed that the water quality was good in Duobukuer Nature Reserve,the sampling points 5,6 and 12 presented β-pollution,and other sampling points were in an oligosaprobic-clean state.
