摘要 为了掌握红枫水库浮游植物金属富集特征,分别于2018年冬季(1月)、春季(4月)、夏季(7月)、秋季(10月)对红枫水库浮游植物及其金属含量进行监测分析.结果表明:贵州高原红枫水库浮游植物金属富集含量大小为:Ca > Fe > Mg > Mn,Ca占金属含量总比重的73.9%,且金属含量四季变化差异显著,总体季节变化规律为:冬季 > 秋季 > 夏季 > 春季,冬季浮游植物金属富集总量为273.13mg/g,春季浮游植物金属富集总量为183.82mg/g.②贵州高原红枫水库采样点浮游植物金属富集含量排列顺序为:三岔河 > 后湖 > 大坝 > 将军湾 > 后午 > 花渔洞,红枫水库三岔河和后湖浮游植物富集金属含量高,花渔洞浮游植物富集金属含量较低,且Fe和Mn相关性显著,Ca与Mg可能具有同源性.③RDA分析表明,4季的浮游植物金属含量与蓝绿藻有较强的相关性.研究显示,红枫水库中浮游植物金属含量具有显著的时空变化特征,且在秋冬季浮游植物金属含量与优势藻种具有显著相关性.

Abstract:In order to understand the metal accumulation characteristics in phytoplankton in Hongfeng Reservoir, the phytoplankton and its metal content in Hongfeng Reservoir were monitored and analyzed in winter (January), spring (April), summer (July), and autumn (October) in 2018. The results indicated that the metal concentration in phytoplankton in Hongfeng Reservoir of Guizhou Plateau was in the order of Ca > Fe > Mg > Mn, and Ca accounted for 73.9% of the total metal content. In addition, there was a significant seasonal difference in metal content. The total metal accumulation in phytoplankton in winter was highest at 273.13mg/g, followed by autumn and summer, the accumulation in spring was lowest at 183.82mg/g. The spatial order of metal enrichment of phytoplankton at the sampling site was: Sancha > Houhu > Daba > Jiangjun > Houwu > Huayudong. The metal content from sample sites in Sancha and Houhu was high, while that in Huayudong was low. The correlation between Fe and Mn was significant. Ca and Mg might have common sources. The RDA analysis showed that there was a strong relativity between the metal content in phytoplankton in four seasons and both of cyanobacteria and chlorophyta. These results showed that the metal content of phytoplankton in Hongfeng Reservoir had a significant spatial-temporal variation, and a significant correlation with the dominant algae species in autumn and winter.
