【摘要】：于2011年不同季节对山仔水库水体物理和化学指标、浮游植物和浮游动物进行监测,分析了蓝藻门微囊藻属在水平和垂向空间上的分布规律,探索了微囊藻属生物量与环境因子的相关关系.结果表明,不同季节山仔水库大坝断面微囊藻属细胞丰度在105~107L-1之间变化,夏季水体微囊藻属细胞丰度达到107L-1,浮游植物群落中微囊藻属的比例高达95%以上;冬季水体微囊藻属细胞丰度为105L-1,浮游植物群落中微囊藻属的比例在20%~45%.5-9月,表层水体微囊藻属细胞丰度高于底层水体,秋末到冬季水体表层与底层的微囊藻属细胞丰度相差不大,水温与微囊藻属细胞丰度呈显著正相关,轮虫与微囊藻属细胞丰度呈显著负相关.分析可知,水温分层是影响山仔水库微囊藻属垂向分布的重要因素之一.
[Abstract]:The physical and chemical indexes, phytoplankton and zooplankton of Shanzi Reservoir were monitored in different seasons in 2011. The distribution patterns of Microcystis in horizontal and vertical directions were analyzed. The relationship between microcystis biomass and environmental factors was explored. The results showed that the cell abundance of Microcystis in different seasons varied between 105~107L-1. In summer, the abundance of microcystis in water reaches 107L-1, and the percentage of microcystis in phytoplankton community is more than 95%, while in winter, the abundance of microcystis is 105L-1, and the proportion of microcystis in phytoplankton community is between 20 and 45.5-9 months. The cell abundance of microcystis in the surface water was higher than that in the bottom water, but there was no significant difference between the surface and bottom water from autumn to winter, and there was a significant positive correlation between the water temperature and the cell abundance of microcystis. There was a significant negative correlation between rotifer and cell abundance of Microcystis. Water temperature stratification was one of the important factors affecting the vertical distribution of Microcystis in Shanzi Reservoir.
