Abstract

Abstract: The distribution and community structure changes of macrobenthic invertebrates in Baiyangdian Lake, two upstream reservoirs and four upstream rivers were investigated in different seasons in May, August and October in 2019. The dominant species were all pollution-resistant species in Baiyangdian Basin. The biomass mainly showed that the south was higher than the north in Baiyangdian Lake. The biodiversity of macrobenthic invertebrates showed that the central region was higher than the coastal region in Baiyangdian Lake. The changes of biomass and abundance in the two reservoirs were similar, which were higher in spring and autumn than in summer. Fuhe River, Xiaoyihe River and Jumahe River showed the lowest biomass in spring, while Shahe River had the highest biomass in spring. The biodiversity analysis of the four rivers showed that the biodiversity in spring was higher than that in other seasons. In a word, in terms of biomass and biodiversity, the upstream rivers and reservoirs mainly show significant differences in different seasons, while the differences between different regions are not significant.- DOI:10.3969/j.issn.1000-1565.2022.04.013白洋淀流域大型底栖无脊椎动物群落结构分析武志鑫,王玺,刘瑀璇,孙枭琼,王宏伟(河北大学生命科学学院,生命科学与绿色发展研究院,河北保定 071002)摘要:2019年5月、8月和10月对白洋淀流域的淀区、2个上游水库和4条上游河流中大型底栖无脊椎动物的不同季节群落结构变化进行了调查,发现其优势物种均为耐污种.淀区群落结构主要表现出受区域性影响较大,受季节性影响不大的特点,分析其生物量和生物多样性指数,呈现出淀区南部生物量高于淀区北部,淀区中心生物多样性高于淀区边缘;2个水库生物量与丰度变化具有一定的相似性,均表现为春季和秋季高于夏季;府河、孝义河和拒马河表现为春季生物量最低,沙河春季生物量最高,在4条河流中春季生物多样性均高于夏、秋季.总之,从生物量和生物多样性两方面来看,上游河流和水库主要表现为不同季节间差异显著,而不同区域间差异不显著.关键词:白洋淀流域;大型底栖无脊椎动物;群落结构中图分类号:Q89 文献标志码:A 文章编号:1000-1565(2022)04-0424-09Analysis of community structure of macrobenthic invertebrates in Baiyangdian BasinWU Zhixin, WANG Xi, LIU Yuxuan, SUN Xiaoqiong, WANG Hongwei(Institute of Life Science and Green Development,School of Life Sciences, Hebei University, Baoding 071002, China )Abstract: The distribution and community structure changes of macrobenthic invertebrates in Baiyangdian Lake, two upstream reservoirs and four upstream rivers were investigated in different seasons in May, August and October in 2019.
