摘　　要：2014年7月对扎龙湿地8个采样点进行了浮游植物调查,共鉴定出浮游植物6门95种(包括变种、变形),以绿藻门和硅藻门为主。同时采用浮游植物功能群分类的方法,共划分出了22个不同的功能群,常见功能群(功能群出现频率大于65%)共有12个,分别为功能群MP、P、D、C、J、Lo、F、N、X1、X2、W1、TD,其中功能群MP、P、D、C在每个采样点都能监测到。此外,1#东升水库以功能群P和D占优势,2#克钦湖度假村以功能群J和C占优势,3#克钦湖以J、C、MP占优势,4#翁海排干以功能群MP和P占优势,5#扎龙湖心以功能群Lo和N占优势,6#扎龙湖以功能群MP、P和N占优势,7#龙湖以功能群MP、P占优势,8#吐木柯小桥以功能群Z、P占优势。并用基于浮游植物功能群的Q指数法对水质进行评价,Q值大小关系:7#>6#>8#>5#>4#>3#>1#>2#,评价结果为:1#东升水库和2#克钦湖度假村水质为中等,3#克钦湖水质好,4#翁海排干、5#扎龙湖心、6#扎龙湖、7#龙湖、8#吐木柯小桥水质均极好,只是轻度污染,这与多样性指数评价结果较为一致。We took the phytoplankton summer survey of Zhalong wetland on 8 sampling points, in July,2014.There were 6phylas and 95 speicies（including varieties, forms）.Chlorophyta and bacillariophyta were the major part of the phytoplankton.By using the method of functional group classification, the phytoplankton was divided into 22 different functional groups.There were twelve common functional groups（functional group frequency was greater than 65%）, MP、P、D、C、J、Lo、F、N、X1、X2、W1、TD. MP, P, D, C can be detected at each sampling point. In addition, 1# P and D were dominant functional groups; 2# J and C are the dominant functional groups;3# J、C and MP were dominate functional groups; 4# P and MP were the dominant functional groups; 5# Lo and N were dominate functional groups;6# MP、P and N were dominate functional groups;7# P and MP were the dominant functional groups; 8# P and D were dominate functional groups. What＇s more, based on the Q index method, we evaluated the water quality of the functional group. The relationship of the Q value was 7#6#8# 5# 4# 3# 1# 2#.The evaluation results were：1# and 2# were medium; 3# was good quality;4#、5#、6#、7#、8# were excellent quality, just slight pollution. This result was consistent with the result of diversity index and evaluation.
