| 2011年6月调查了渭河流域陕西段4座水库的浮游生物种群结构,并根据浮游生物生物量对4座水库的营养类型进行了划分。结果表明,4座水库浮游植物共计8门、40种(属),细胞密度为12.00×104～132.50×104个/L,浮游植物生物量为0.3944～2.7670mg/L;浮游动物分为4大类、26种,种群密度为20～2150个/L,生物量为0.0010～1.8520mg/L,各水库浮游生物种群密度和生物量的大小顺序为西郊水库>桃曲坡水库>西骆峪水库>石头河水库。根据有关营养类型划分标准,4座水库中,西郊水库和桃曲坡水库为中营养水库,石头河水库和西骆峪水库为贫营养水库,并对各水库浮游生物的种群结构与营养类型之间的响应关系以及营养类型的成因进行了讨论和分析。 |

| The plankton population composition of 4 reservoirs in Shaanxi Province was surveyed. Overall forty species(genera) belonging to 8 phylum of phytoplankton and twenty six species belonging to 4 phylum of zooplankton were observed from the 4 reservoirs. The densities of the phytoplankton and zooplankton were 12. 00 x 104一132.50x 104 ind. /L and 20一2 150 ind. /L，respectively. The biomasses of the phytoplankton and zooplankton were 0.3944一2.7670 mg/L and 0. 0010一1.8520 mg/L, respectively. The order of density and biomass of plankton of 4 reservoirs was Xijiao Reservoir，Taoqupo Reservoir, Xiluoyu Reservoir and Shitouhe Reservoir. According to the relevant standards，Xijiao Reservoir and Taoqupo Reservoir were marked as middle trophic type and Shitouhe Reservoir and Xiluoyu Reservoir were marked as poor trophic type. At last ，the correlation of trophic type and plankton population structure and the cause of trophic type of the 4 reservoirs were analyzed and discussed. |
