云南兰坪箐花甸国家湿地公园大型底栖动物多样性调查
Investigation on the Diversity of Benthic Macrofauna in Qinghuadian National Wetland Park,Lanping,Yunnan Province
摘要
Abstract
This study investigated water quality parameters and benthic macrofauna diversity in typical riverine habitats of Lanping Qinghuadian National Wetland Park using standardized sampling methodologies.Results indicate favorable overall water quality and high biodiversity of benthic macrofauna.Across six sampling sites,a total of 23946 individuals were collected,belonging to 59 spe-cies within 45 families and 9 orders,including 55 aquatic insect species and 4 non-insect taxa.The community exhibited pronounced dominance by a limited number of taxa,with uneven species distribution.Dominant taxa included Nemouridae(Plecoptera,relative a-bundance:22.55%),Orthocladiinae(Diptera,20.99%)and Baetidae(Ephemeroptera,9.76%).Significant differences in species diversity and richness were observed between riverine streams and swamp streams,driven by habitat heterogeneity,substrate composi-tion,flow velocity,and water quality parameters.These findings provide critical insights for benthic macrofauna conservation,habitat management,and biodiversity research in high-altitude wetland ecosystems.关键词
