英文摘要	为了解浙江饮用水源地浮游动物体积多样性及对水体综合营养状态(TLIc值)的响应特征,对16个饮用水源地(H1-H8为河网型,K1-K8为水库型)展开了水质参数、浮游动物群落生物体积及其多样性指数的季节调查.结果表明,生物体积密度的季节变化以1月(0.681 mL/L)>4月(0.443 mL/L)>10月(0.252 mL/L)>7月(0.229 mL/L),各季的第一优势种分别为汤匙华哲水蚤(Sinocalanus dorrii)(1月)、晶囊轮虫(Asplanchna sp.)(4月)、粗壮温剑水蚤(Thermocyclops dybowskii)(7月)和长额象鼻溞(Bosmina longirostris)(10月).河网浮游动物生物体积以轮虫(44.6%)和枝角类(23.4%)为主,水库则以哲水蚤(39.5%)和轮虫(29.0%)为主.夏秋季浮游动物体积多样性指数(P<0.01)和物种多样性指数(P<0.05)与lg(浮游动物/浮游植物生物量比率)[lg(ZB:PB)]之间均有显著的相关性,水库中仅浮游甲壳动物体积多样性指数与lg(ZB:PB)之间有极其紧密的相关性(R2=0.77).与物种多样性指数响应环境效应相比,甲壳动物的体积多样性指数(P<0.01)能更好地指示夏秋季河网的TLIc值,这归因于甲壳动物个体数(ind./L)转换成了生物体积密度(mL/L)过程中有效信息的放大.; In order to understand the size diversities of the zooplankton community and response characteristics of the comprehensive water bodies by trophic level index (TLIc value), a seasonal investigation was conducted on zooplank-ton size diversities from two types of 16 drinking water sources (H1-H8 for rivers, K1-K8 for reservoirs) from January to October 2011 in Zhejiang Province. The results showed that seasonal variations in the biovolume density of zoo-plankton from high to low were January (0.681 mL/L), April (0.443 mL/L), October (0.252 mL/L), and July (0.229 mL/L). The first dominant species of January, April, July, and October wereSinocalanus dorrii,Asplanchna sp.,Thermocyc-lops dybowskii, andBosmina longirostris respectively. Zooplankton were mainly Rotifera (44.6%) and Cladocera (23.4%) in the rivers by their biological volume, while Calanoida (39.5%) and Rotifera (29.0%) in the reservoirs. There were significant relationships between lg 10 transformed zooplankton/phytoplankton biomass ratio [lg (ZB:PB)] and size diversi-ties (P<0.01) or species diversities (P<0.05) of zooplankton in the drinking water sources during summer and autumn, and crustacean zooplankton size diversity index was significantly positive correlated with lg (ZB:PB) (R2=0.77) in the reservoirs. Crustaceans size diversity (P<0.01) were more reliable toTLIc value of the rivers than the species diversity during summer and autumn, supported by the useful information amplification from the numbers of crustaceans (ind./L) converting into biovolume density (mL/L).; 浙江省自然科学基金青年基金; 浙江省重中之重学科开放基金(KF2016003)资助 [Supported by the Zhejiang Province Science Foundation for Youths; the Open Foundation of Zhejiang Provincial Top Key Discipline (KF2016003)]; 中国科学引文数据库(CSCD); 2; 407-413; 41
