摘要
2012年8月至2013年4月对柘林水库大型底栖动物进行了4次调查,共采集到底栖动物32种,隶属3门18科31属,其中软体动物门12种、节肢动物门12种、环节动物门8种。优势种为中华颤蚓Tubifex sinicus。柘林水库大型底栖动物年平均密度为620.42ind./m2,年平均生物量为16.05g/m2。密度季节变化为春季高,夏季低,生物量季节变化为春季高,秋季低。库湾及库区底栖动物较为丰富。功能摄食群中撕食者、滤食者和收集者季节变化明显,刮食者与捕食者变化较为平稳。水库中底栖动物优势类群多为耐低氧的寡毛类。
The community structure of macrozoobenthos in the Zhelin reservoir was studied from August, 2012 to April,2013.In total,32 taxa belonging to 3 phyla,18 families and 31 genera were identified,The dominate specie was Tubifex sinicus.Zhelin reservoir’s annual average density was 620.42 ind./m2 and biomass was 16.051 g/m2 .Higher density and biomass were found in low temperature seasons.Given the Functional Feeding Groups,the gather-collectors,shredder and collector had obviously seasonal changes, obviously,but while the scrapers and predator changed relatively stable.Compared with other reservoirs, the dominant species of most reservoirs were Oligochaetes.
