摘要/Abstract

摘要： 调查了2018年白洋淀大型底栖动物、水质和沉积物特征，分析了大型底栖动物群落结构与环境因子的关系。结果表明：白洋淀大型底栖动物6纲21种，以腹足纲和昆虫纲为主；平均生物量和平均生物密度具有时空差异，夏季平均生物量最高，南刘庄最大；春季平均生物密度最高，东田庄最大；利用多样性指数进行水质评价，发现白洋淀水环境质量处于较低水平，水体中的氮、磷和沉积物中的碳、氮含量相对较高；影响底栖动物的主要水质环境因子和沉积物环境因子分别为NO₃^--N、TN、温度、TOC和NO₃^--N、pH、NH₄⁺-N。本研究结果可为白洋淀大型底栖动物的修复与管理提供依据。

Abstract: The characteristics of macrozoobenthos and environmental factors in water and sediment in Baiyangdian Lake were investigated in 2018. The relationship between community structure of macrozoobenthos and environmental factors were analyzed. Results showed that macrozoobenthos consisted of 6 classes and 21 species in Baiyangdian Lake, with Gastropoda and Insecta being the dominant classes. The mean biomass and abundance had temporal and spatial variations. The mean biomass of macrozoobenthos peaked in summer, while the mean abundance of macrozoobenthos peaked in spring. The maximum of mean biomass was found in Nanliuzhuang site, while the maximum of mean abundance was found in Dongtianzhuang site. Quantified by the diversity index, water quality of Baiyangdian Lake was at a low level. Nitrogen and phosphorus contents in water and carbon and nitrogen in sediment were relatively high. NO₃^--N, TN, temperature and TOC in water and NO₃^--N, pH and NH₄⁺-N in sediment were the main environmental factors influencing macrozoobenthos. Our results could provide a basis for restoration and management of macrozoobenthos in Baiyangdian Lake.

Key words: macrozoobenthos, water environmental factor, sediment environmental factor, redundancyanalysis.
