摘　　要：对武汉市5个城郊湖泊的底栖动物群落组成及与水环境因子的关系进行了研究.调查中共检出底栖动物29种,主要优势种为霍甫水丝蚓(Limnodrilus hoffmeisteri)、环棱螺(Bellamya sp.)和水丝蚓(Limnodrilus sp.),均为喜有机质的耐污种;水体理化指标表明5个湖泊呈高度富营养化,除叶绿素a质量浓度之外,各湖的理化因子间存在显著性差异.典范分析(CCA)与冗余分析(RDA)分析表明,水体中的总氮(TN)和总磷(TP)与环节动物密度正相关,与软体动物呈负相关;透明度(SC)与各湖泊优势种相关性差异较大;叶绿素a则对优势种影响较弱或无明显影响.基于底栖动物指示物种进行水质评价结果显示,Wright指数评级偏优,Goodnight-Whitley生物指数及BPI相对重要性指数近似,调查的5个城郊湖泊处于轻污染至β-中污染,与水质调查的结果相近.研究有助于准确掌握武汉市城郊湖泊生态系统的特征和状态,为城郊湖泊资源的合理利用和生态修复提供科学依据.This study investigates the composition of macroinvertebrate communities and their relationships with water environmental factors in five suburban lakes located in the outskirts of Wuhan.A total of 29 species of macroinvertebrates were collected,with dominant species being Limnodrilus hoffmeisteri,Bellamya sp.,Limnodrilus sp.,all of which are organic matter tolerant species.The physicochemical indicators of the water bodies showed that the five lakes were highly eutrophic,and there were significant differences in the physicochemical factors among the lakes,except for the concentration of chlorophyll a.Canonical correspondence analysis(CCA)and redundancy analysis(RDA)showed that total nitrogen(TN)and total phosphorus(TP)in the water were positively correlated with densities of annelids,but negatively correlated with mollusks.Transparency(SC)showed significant differences in correlations with dominant species among lakes,while Chlorophyll a had weak or no apparent influence on the dominant species.When assessing water quality based on macroinvertebrate indicator species,it was found that the Wright index rating was slightly favorable,and the Goodnight-Whitley index and the BPI(biotic index of pollution)were relatively important,indicating that the water quality of the surveyed five suburban lakes ranged from light pollution to β-moderate pollution,consistent with the results of water quality surveys.This study is helpful to understand accurately the characteristics and status of suburban lake ecosystems of Wuhan City,providing scientific basis for the rational utilization and ecological restoration of suburban lake resources in Wuhan City.
