  • 为探究东莞城市湿地公园浮游植物群落结构特征、功能类群及其与环境因子的关系,于2019年4—12月按季度在东莞生态园中央岛群水域和月湖湖区设置7个采样站点,采用传统分类法、功能群分类法及综合营养状态指数法等对该园区水环境中浮游植物群落结构和环境因子进行了调查分析。结果表明:在东莞生态园共鉴定出浮游植物7门137种(属),其中,绿藻门物种数最多,全年优势种均来自蓝藻门;浮游植物年平均丰度和生物量分别为(16.83±1.97)×107 ind./L和(23.00±3.00)mg/L,丰度和生物量在季节间存在显著性差异(P<0.05),且季节和湖区间存在显著交互作用(P<0.05);聚类分析(CA)显示,浮游植物物种组成在季节间存在显著性差异(P<0.05);东莞生态园浮游植物可划分为24个功能群,其中D、F、H1、J、Lo、MP、P、S1、SN、W1、X1和Y为优势功能群,且存在季节演替;RDA分析显示,水温(WT)、磷酸盐(PO3--P)、氨氮(NH4+-N)、pH和总磷(TP)是影响浮游植物优势种和优势功能群的主要环境因子;结合单因子水质评价法、综合营养状态指数(TLI)、功能群Q指数、浮游植物现存量、叶绿素a和浮游植物多样性指数对东莞生态园进行水质评价综合分析显示,水体有机污染严重,主要污染物质为氮。研究表明,东莞生态园浮游植物群落以蓝藻为优势种,水环境处于中度富营养状态或中污染状态,需严格控制外来污染并加强水体自身净水能力。
