【摘要】 为研究挠力河湿地大型底栖动物功能特性的季节变化,及其与底质、植被之间的关系,于2016年7月份—2017年5月份在挠力河湿地设置11个采样点进行大型底栖动物采集和分析。结果表明:在挠力河湿地发现大型底栖动物共9目18科42种,划分为6种摄食功能群,即捕食者(PR)、杂食者(OM)、直接集食者(GC)、过滤收集者(FC)、刮食者(SC)和撕食者(SH),其中,刮食者和捕食者是优势功能群,物种数分别为19种和11种;6种运动功能群,即漂浮者(PL)、潜水者(DI)、附着者(CN)、扩张者(SP)、攀爬者(CM)和挖掘者(BU),其中附着者为优势功能群,物种数多达25种。底质类型、水生维管束植物等均是影响大型底栖动物生长和分布的因素,同样也影响其功能群的变化。更多还原

【Abstract】 The experiment was conducted to study the seasonal variation of functional traits for macroinvertebrates in Naolihe Wetland and the effect by environment factors,collected macroinvertebrates from 11 sampling sites from the summer of2016( July) to the spring of 2017( May). The macroinvertebrates in 42 species of 18 families of 9 orders are divided into6 feeding groups,including Predators,Omnicorous,Gathers-collectors,Filter-collectors,Scrapers and Shredders. Scrapers and Predators are dominant functional groups among them,the species number are 19 and 11. The total of 6 movement groups,including Planktonic,Divers,Clingers,Sprawlers,Climbers and Burrowers. Clingers is the main functional group of all,and the species number is 25. The sediment type,and aquatic vascular bundle are the factors affecting the growth and the variation of functional groups for macroinvertebrates.更多还原
