摘要
为揭示“渔光互补”对富营养化水体中浮游植物群落的影响,以灌湖水库上湖和枫林水库(均安装光伏板)、灌湖水库下湖和西潭水库(均未安装光伏板)为研究对象,通过野外调查和采样分析了光伏板对水库浮游植物种群结构变化的影响。研究结果表明,4座水库均处于富营养化状态。水库安装光伏板后,浮游植物的密度和生物量均增加了,但是对浮游植物的种类和丰富度影响较小。光伏板对浮游植物的特征影响较大,浮游植物的香农多样性指数和均匀度指数均显著增加。产生这一现象的原因主要是由于光伏板遮挡强光直晒和减缓水体降温,并在富营养化条件下有利于浮游植物的生长繁殖。
In order to reveal the effect of “fishery and photovoltaic” on the phytoplankton community in eutrophic water bodies, this study took the upper Huanhu lake and Fenglin reservoir(both with photovoltaic panels), and the lower Huanhu lake and Xitan reservoir(both without photovoltaic panels) as the research objects, and analyzed the effect of photovoltaic panels on the change of phytoplankton population structure in the reservoir through field survey and sampling. The results showed that all four reservoirs were in eutrophication. After the installation of photovoltaic panels, the density and biomass of phytoplankton increased, but the effect on phytoplankton species and abundance was small. The PV panels had a greater impact on the characteristics of phytoplankton, and the Shannon diversity index and evenness index of phytoplankton were significantly increased. The reason for this phenomenon is mainly due to PV panels shading from direct sunlight and slowing down the cooling of the water column, and favoring the growth and reproduction of phytoplankton under eutrophic conditions.
