摘要:
为了解贵州高原百花水库浮游植物功能群的动态变化与环境因子的关系,于2020年1—12月(除2月份)对浮游植物与水环境指标进行逐月采样,利用RDA和相关性分析,结合群落更替指数(BC)对百花水库浮游植物功能群进行分析.结果表明:1)2020年百花水库共鉴定出浮游植物7门64种,其中绿藻门物种数最多为27种,其次为硅藻门和蓝藻门,浮游植物总生物量的范围为124.8~2235.4 μg/L;2)百花水库浮游植物共归类为26个功能群,其中S1、LM、J、B、P、D、MP、Y和W1为优势功能群,多数适宜生存在中营养的水体.功能群B、D和LM是长期处于优势地位的功能群,以梅尼小环藻(Meneghiniana cyclotella)、尖针杆藻(Synedra acus)和飞燕角甲藻(Ceratium hirundinella)为主;3)综合营养状态指数(TLI(Σ))为36.90~50.20,生态状态指数(Q)值为0.73~3.46,说明百花水库处于中营养状态.4)分析结果表明,水温和pH共同影响浮游植物优势功能群的动态变化.

Abstract:
To determine the relationship between the dynamic changes of phytoplankton functional groups and environmental factors, the observation data on water quality and phytoplankton community were analyzed monthly from January 2020 to December 2020 (except February). This article used RDA and correlation analysis, combined with community turnover index (BC) to analyze the phytoplankton functional groups in Baihua Reservoir, Guizhou Plateau. The results showed that:1) In 2020, 64 species of phytoplankton in 7 phyla were identified in Baihua Reservoir, among which the numbers of Chlorophyta species were up to 27, followed by Diatom and Cyanophyta. The total biomass of phytoplankton ranged from 124.8 to 2235.4 μg/L; 2) The phytoplankton in Baihua Reservoir was classified into 26 functional groups, of which S1, LM, J, B, P, D, MP, Y and W1 were the dominant functional groups, and most of them are suitable for survival in medium nutrient water bodies. Functional groups B, D and LM were the long-term dominant functional groups, mainly represented by Meneghiniana cyclotella, Synedra acus and Ceratium hirundinella, respectively; 3) The comprehensive trophic level index (TLI(Σ)) was between 36.90 and 50.20, and the ecological status index (Q) value ranged from 0.73 to 3.46, indicating that Baihua Reservoir was in a mesotrophic state; 4) The analysis results showed that water temperature and pH together affect the dynamic changes of the dominant functional groups of phytoplankton.
