浮游

Based on data collected at four stations in Daning River in the spring of 2004 and 2005, phytoplankton community structure, vertical distribution, abundance, biomass, C contents, diversity index, richness index and evenness index were studied. The causes of eutrophication and water blooms in Daning River were analysed and control measures were then put forward. The dominant species were Asterionella Formosa, Cryptomonas ovata, Cyclotella caspia, Stephanodiscus neoastraea in the spring of 2004 and those were Pandorina morum, Eudorina elegans, Cyclotella caspia, Cryptomonas ovata in the spring of 2005. Average cell densities, biomass, C contents in the spring of 2004 and 2005 were 171.1×10^5 cells/L, 12.2 mg/L, 1732.2g C/L and 113.1×10^5 cells/L, 10.1 mg/L, 1395.9g C/L, respectively.

各淀区浮游植物生物量平均为45.261，以寨南最大（113.138），藻淀最小（0.862）；叶绿素含量平均为7.573 3，其中南刘庄最大（17.690 4），藻淀最小（0.245 7）；最高生产层以碳计的日产量（g／（m3 ·d））平均为0.285，其中南刘庄最大（1.055），藻淀最小（0.015），水柱日产量（g／（m2 ·d））平均为0.431，其中寨南最大（1.001），藻淀最小（0.013）。

The single-celled phytoplankton included 116 inshore wide distribution species, 31 inshore warm-water species and 26 inshore temperate species, and the vascular plants were of 6 ecological groups, i.e., halophtes (24 species), hydrophtes (22 species), amphiphytes (35 species ), mesopllytes (103 species), zerophytes (6 species), and psammons (4 species). Halophtes, hydrophtes, and amphiphytes were the edificators and dominants, reflecting the azonal feature of the wetland vegetations. The vascular plants were divided into 5 life-forms, including 20 phaenerophytes, 4 chamaephytes, 54 hemicryptophytes, 48 geophytes and 68 therophytes, among which, hemicryptophytes and geophytes accounted for 52.58%, reflecting the relatively important function of cold and wet climate and local water-accumulated bottomland environment on the vascular flora formation.
