摘要:

文章结合模拟升温和营养盐加富, 于2016年8月和2017年1月研究了夏季和冬季大亚湾海域浮游生物群落代谢特征, 以期深入了解浮游生物对升温和富营养化作用的响应机制。结果表明: 升温和营养盐输入均会影响浮游生物总初级生产力(GPP)和群落呼吸率(CR), 且GPP对环境的响应更敏感。夏季GPP除在培养前期(24h)极高温条件下受到显著抑制外, 营养盐输入的影响比温度的影响作用更显著; 而冬季GPP和CR受升温效应的影响显著(p<0.05)。总体看来, 升温效应和营养盐输入均能影响浮游生物群落碳代谢平衡, 导致海洋生态系统的稳定性降低, 进而影响海洋生物多样性以及渔业资源产出的数量和质量。

Abstract:

Characters of plankton community metabolism of Daya Bay were studied using data collected in August 2016 and January 2017. The possible effects of nutrients input were discussed to understand the response mechanism of plankton to warming and eutrophication based on simulation experiments. The results indicated that both GPP (gross primary production) and CR (community respiration) were influenced by warming and nutrients input, and response of GPP to environment was seriously sensitive. The impact of GPP on nutrients input was more remarkably than that of temperature, except for being significantly inhibited in early cultured stage (24 h) with extremely high temperature conditions. In winter, both GPP and CR were significantly affected by the warming effect (p<0.05). Overall, both warming effect and nutrients input could affect carbon metabolism of plankton community which would lead to the declining of marine ecosystem stability, thereby affecting marine ecosystem stability and biodiversity and quality of marine ecological environment and fishery resource output.

Key words: plankton, community metabolism, nutrients input, Daya Bay
