中文摘要:
      2014年冬季分别对淮河淮南段长吻鮠国家级水产种质资源保护区和淮河荆涂峡鲤、长吻鮠国家级水产种质资源保护区进行采样调查,研究了浮游动物群落结构特征以及关键影响因子。结果表明,两个保护区共发现浮游动物57种,均以原生动物为主体。其中淮南段保护区共38种,包括原生动物22种,轮虫7种,桡足类6种,枝角类3种;荆涂峡保护区共39种,包括原生动物23种,轮虫6种,桡足类7种,枝角类3种。淮南段保护区和荆涂峡保护区浮游动物密度均值分别为(1 313.17±500.53)个/L和(1 601.46±669.02)个/L,生物量均值分别为(0.23±0.12)mg/L和(0.41±0.50)mg/L。浮游动物多样性指数评价结果显示,两处保护区均为中度污染,荆涂峡保护区水质优于淮南段保护区。RDA分析结果表明,水深、浊度、pH、透明度是影响淮南段保护区浮游动物群落结构的主要因素,而荆涂峡保护区的主要影响因子则为水温、总磷、磷酸盐、叶绿素a和高锰酸盐指数。
英文摘要:
      In order to explore the characteristics and key factors of zooplankton community of two national aquatic germplasm reserves in the middle reaches of Huaihe River, samples were collected in winter of 2014. Results indicated a total of 57 zooplankton species were identified in the two germplasm reserves.Among them, 38 species of zooplankton including 22 species of Protozoan(57.89%), 7 species of Rotifers(18.42%), 6 species of Copepods(15.79%) and 3 species of Cladocera(7.89%)were found in the Huainan germplasm reserve;as well as 39 species of zooplankton including 23 species of Protozoan(58.97%), 6 species of Rotifers(15.38%), 7 species of Copepods(17.95%) and 3 species of Cladocera(7.69%) were found in the Jingtuxia germplasm reserve.Protozoa were on predominance in the two germplasm reserves (22 and 23 species respectively) and the dominant groups are ciliates with shell of Protozoa.The average density of zooplankton in Huainan germplasm reserve was (1313.17±500.53) ind./L, and (1601.46±669.02)ind./L in Jingtuxia germplasm reserve, while the average biomass was (0.23±0.12)mg/L and (0.41±0.50)mg/L respectively.According to the standard of diversity index evaluation, the two germplasm reserves were moderately polluted and the water quality in Jingtuxia germplasm reserve was better than that in Huainan germplasm reserve.The result of Redundancy Analysis(RDA) shows that Depth, Tur, pH and SD were the main factors which affected the zooplankton community structure of Huainan germplasm reserve. Simultaneously, T, TP, PO43--P,Chl.a, and CODMn were proved to be the main driving factors which influenced the zooplankton community structure of Jingtuxia germplasm reserve.
