摘要：该研究旨在探讨滇池湖滨湿地水生昆虫群落在时空上的特征以及与环境因素的关系,并为湖滨湿地的修复提供理论支持.在2018年8月至2019年3月期间,对滇池的4个区域的5个湖滨湿地的水生昆虫和水质状况进行了季度调查.利用优势度指数和4个物种多样性指数分析水生昆虫群落的特征,并使用Pearson相关性分析研究水生昆虫群落与环境因素之间的关系.调查共记录了7目31科的水生昆虫,涵盖了69个分类单元.其中,双翅目水生昆虫个体数和分类单元数最多,占总个体数的59.07%和总分类单元数的47.84%.划蝽科(Corixidae)一种、多足摇蚊属一种(Polypedilum sp.)和摇蚊属一种(Chironomus sp.)是滇池湖滨湿地的优势分类单元.在时间尺度上,滇池湖滨湿地的水生昆虫群落最为复杂的是春季,其次是夏季和冬季,而秋季相对简单.在空间尺度上,滇池东岸和东北岸的水生昆虫群落较为复杂,南岸次之,而西岸和北岸相对简单.相关性分析表明,pH值、溶解氧和化学需氧量是与滇池湖滨湿地水生昆虫群落显著相关的关键水环境因子.
The aim of this study was to explore the temporal and spatial characteristics of the waterborne insect community in the wetlands along the shores of Dianchi Lake,as well as its relationship with environmental factors,and to provide theoretical support for the restoration of lakeshore wetlands.From August 2018 to March 2019,quarterly surveys were conducted on the waterborne insects and water quality of five wetlands in four regions around Dianchi Lake.The dominance index and four species diversity indices were used to analyze the characteristics of the waterborne insect community,and Pearson correlation analysis was used to investigate the relationship between the community and environmental factors.A total of 69 taxonomic units were recorded,covering 31 families and 7 orders of waterborne insects.Among them,the highest numbers of individuals and taxonomic units were observed in the order Diptera,accounting for 59.07%and 47.84%of the total individuals and taxonomic units,respectively.One taxonomic unit each from the families Corixidae,Polypedilum sp.,and Chironomus sp.were identified as the dominant taxonomic units in the wetlands.The waterborne insect community in the wetlands was found to be most complex in spring,followed by summer and winter,and relatively simple in autumn.In terms of spatial distribution,the waterborne insect community on the east and northeast shores of Dianchi Lake was the most complex,followed by the south shore,while the west and north shores were relatively simple.Correlation analysis indicated that pH,dissolved oxygen,and chemical oxygen demand were key water environmental factors significantly correlated with the waterborne insect community in the wetlands along the shores of Dianchi Lake.
