| 摘 要： | 为了阐明大清河摇蚊幼虫群落结构特征及其与环境的关系,2013年7月和10月对大清河摇蚊幼虫群落结构特征进行了季度调查。共采集到摇蚊幼虫46种,隶属4亚科25属,优势种为苍白摇蚊(Chironomus pallidivittatus Malloch)和柔嫩雕翅摇蚊(Glyptotendipes cauliginellus Kieffer)。结果显示大清河摇蚊幼虫群落具有季节和地区差异性。摇蚊幼虫平均密度和生物量、Shannon多样性指数、Pielou均匀度指数和Simpson优势度指数均表现为夏季大于秋季。根据密度和生物量的聚类分析表明不同区域摇蚊幼虫可分属3大类。通过Margalef丰富度指数与经纬度之间的相关性分析发现,大清河摇蚊幼虫Margalef丰富度指数与经度呈负相关,与纬度无显著相关性。采用Shannon多样性指数和Hilsenhoff生物指数对大清河的水质进行了初步评价,结果表明大清河不同流域的污染等级不完全一致,水质情况比较复杂,但大部分地区已达富营养化水平,建议对其投入更多的关注和保护。

| Abstract: | To study the correlation between community structure of chironomid larvae and environment, community structure of chironomid larvae in Daqing River was investigated in July and October in 2013. 46 species of chironomids belonging to 25 genera and 4 subfamilies were identified. Chironomus pallidivittatus and Glyptotendipes cauliginellus were the most abundant. The results revealed that chironomid larvae community in Daqing River exhibited seasonal and regional fluctuations. The average density and biomass were higher in summer than that in autumn. Shannon diversity index, Pielou evenness index and Simpson dominance index all suggested that species diversity was higher in summer. Clustering analysis of chironomid density and biomass suggested that Daqing River could be divided into three different areas. The correlation analysis showed that Margalef abundance index had negative correlation with longitude, but had no significant correlation with latitude. Bioassessment of water quality using Shannon diversity index and Hilsenhoff biotic index showed that the water quality in Daqing River was rather complex, with inconsistent pollution levels in different areas. However, most areas of the river reached eutrophication level, indicating that immediate action was needed to control further damage to the ecosystem. |
