摘    要:为研究池塘工业化生态养殖系统中浮游植物群落结构特征,初步阐明其生态学机理,试验以团头鲂为养殖品种,设置高、低两个养殖密度,采用多样性指数、均匀度指数评价了系统中6个试验分区的浮游植物群落结构特征。结果显示,各试验区共鉴定出藻类5门92种,其中绿藻46种、蓝藻15种、裸藻15种、硅藻10种、隐藻5种、甲藻1种。浮游植物种类数、多样性指数、均匀度指数、绿藻丰度、绿藻比例均表现为进水区、净化区、循环区、循回区低密度养殖区高密度养殖区排水区;浮游植物总丰度、蓝藻丰度、蓝藻比例均表现为进水区、净化区、循环区、循回区低密度养殖区高密度养殖区排水区;上述所有指标在进水区、净化区、循环区、循回区之间都没有表现出明显差异和变化规律。多样性指数所指示的水质状况显示,排水区接近中度污染,高密度养殖区为轻度污染,其余各试验区为清洁水体;除排水区外,其余各试验分区的水质都较好,系统运行良好。

关 键 词:池塘工业化生态养殖系统  水质评价  团头鲂  浮游植物  结构特征

Abstract:In order to research change pattern of phytoplankton community structure in pond industrial eco-aquaculture system and explain it ecological mechanism, the experiment was carried out using Megalobrama amblycephala as aquaculture species and setting two stocking density, Shannon-Wiener diversity index and Pielou uniformity index were used to study the phytoplankton community structure in aquaculture area (including Low stocking density aquaculture area and High stocking density aquaculture area), Inlet area, Outlet area, Purification area, Recirculation area, Back area of pond industrial eco-aquaculture system. The results showed that 5 classes including 92 species have been founded, including Chlorophyta 46 species, Cyanophyta15 species, Euglenophyta 15 species, Bacillariophyta10 species, Cryptophyta5 species, Pyrrophyta 1 species. The numbers of phytoplankton species, biodiversity indexes, uniformity indexes, chlorophyta biomass and its proportion accounting for the total phytoplankton followed the order of Inlet area, Purification area, Recirculation area, Back area > Low stocking density aquaculture area > High stocking density aquaculture area> Outlet area.The total biomass of phytoplankton, Cyanophyta and its proportion accounting for the total phytoplankton followed the order of Inlet area, Purification area, Recirculation area, Back area < Low stocking density aquaculture area < High stocking density aquaculture area < Outlet area. However, all the above parameters in Inlet area, Purification area, Recirculation area, Back area didn`t show significant differences and change trend rule. It could be concluded according to the biodiversity that the water quality in water outlet area was in middle pollution level, the water quality in High stocking density aquaculture area was in light pollution level, and other 5 areas were in clean level, which mean that the water quality were in good state except water outlet area, and the pond industrial eco-aquaculture system functioned well.
Keywords:Pond industrial eco-aquacultureSsystem  Water quality assessment  Megalobrama amblycephala  Phytoplankton  Structure characteristic
