摘要
为探明花溪三江口河段螺类资源的生物多样性,并为其相关研究、开发和资源保护提供依据,于2010年3—8月对三江口螺类资源进行了调查。结果表明:三江口有螺类13种,隶属于6科10属。大型水生植物覆盖的区域,以大脐圆扁螺与平盘螺的密度最大,分别达592个/m3、619个/m3。其余区域以长角涵螺和光滑狭口螺的密度最大,分别达262个/m3、240个/m3。
Snail resources in Sanjiangkou reach of Huaxi river in Guiyang city were investigated from March to August in 2010 to explore the biological diversity of snails and provide the basis for relevant research,development and resources conservation.The results showed that there were 13 snail species belonging to 10 genera,6 families in Sanjiangkou reach.The dominant species were Hippeutis umbilicalis and Valvata cristata in the area covered by macrophytes and the biomass per cubic meter were up to 592 and 619 respectively.The dominant species in other regions were Alocinma longicornis and Stenothyra glabra with the biomass per cubic of 262 and 240 respectively.
