中文摘要:
      于2013年7月至2014年6月每月下旬对滆湖控藻网围内、外和清淤区3个区域轮虫的群落结构进行对比分析。采用淡水浮游生物调查方法,对轮虫种类组成、优势度、现存量和物种多样性及与水质特征参数的关系进行了研究。经鉴定:轮虫共有51种,隶属于14科22属。主要优势种包括:角突臂尾轮虫(Brachionus angularis)、针簇多肢轮虫(Polyarthra trigla)、曲腿龟甲轮虫(Keratella valga)、长肢多肢轮虫(Polyarthra dolichoptera)和长三肢轮虫(Filinia longiseta)等。典型对应分析(CCA) 结果表明,水温(T)、高锰酸盐指数(CODMn)、溶氧(DO)、总氮(TN)和总磷(TP)是影响轮虫生态特征的主要水质因子。多重比较表明,轮虫现存量网围内显著低于网围外(P<0.05),网围内、外皆极显著低于清淤区(P<0.01)。轮虫的生物密度年均值为:网围内[(428±96)ind/L]< 网围外[(939±220)ind/L]<清淤区[(1216±330)ind/L];生物量:网围内[(0.364±0.100)mg/L]< 网围外[(0.991±0.316)mg/L]< 清淤区[(1.589±0.328)mg/L]。本研究表明,鲢鳙鱼控藻对水体富营养化控制有一定效果,而清淤对水体生态修复具有一定的效果。
英文摘要:
      From July 2013 to June 2014, in late every month comparative experiment was carried out to study the community structure of rotifer in three regions of Lake Gehu. The three regions include dredging area, inside and outside of bio-manipulation area. Using freshwater plankton survey method to study the relationship between species composition, dominance, standing crop, species diversity of rotifers and water quality parameters. A total of 51 species of rotifer were collected and identified, belonging to 14 families and 22 genera. Dominant species throughout the year were: Brachionus angularis, Polyarthra trigla, Keratella valga, Polyarthra dolichoptera and Filinia longiseta. Canonical correspondence analysis (CCA) showed that water temperature (T), dissolved oxygen (DO), permanganate index (CODMn), total nitrogen(TN) and total phosphorus(TP) were the main environmental variables affecting the community structure of rotifer. Multiple comparison showed that density of rotifer inside of bio-manipulation pen was significantly lower than that outside of bio-manipulation pen(P<0.05). Inside and outside of bio-manipulation pen extremely significantly lower than dredging area(P<0.01). The annual average density of rotifers: inside of bio-manipulation area [(428±96)ind/L]< outside of bio-manipulation area [(939±220)ind/L]< dredging area [(1216±330)ind/L]. The annual average biomass of rotifers: inside of bio-manipulation area [(0.364±0.100)mg/L]< outside of bio-manipulation area [(0.991±0.316)mg/L]< dredging area [(1.589±0.328)mg/L]. The experiment showed that the silver and bighead carp that control algae have some good effect on eutrophication control, and dredging has certain effect on water ecological restoration.
