微塑料对浮游植物群落的影响研究

Study on the Impact of Phytoplankton Communities in Microplastics

微塑料对浮游植物群落影响研究与海洋环境保护息息相关。搭载向阳红18科考船,随船搭建船基围隔并通过现场采集表层海水,开展不同粒径尺寸、浓度梯度微塑料对小型浮游植物、微型浮游植物以及微微型浮游植物生长影响的实验研究,探索了更加贴近海洋实际条件下微塑料对浮游植物群落生长影响规律。研究发现微塑料对绝大多数海洋浮游植物群落具有抑制作用,但在特定条件下却表现出一定促进作用。该发现为进一步保护海洋环境及后续实验研究提供参考。

The study of the impact of microplastics on phytoplankton communities is closely related to marine environmental protection.Carrying the Xiang Yanghong No.18 Research Vessel,building the base enclosure with the ship and collecting surface seawater on site to carry out experiments on the effects of microplastics of different particle sizes and concentration gradients on the growth of small phytoplankton,micro phytoplankton and picophytoplankton.The purpose of this research is to find out the law of the influence of microplastics on the growth of phytoplankton communities under the actual conditions of the ocean.The study found that microplastics have an inhibitory effect on most of marine phytoplankton communities,but they have a certain promoting effect under certain conditions.The discovery aims to provide a reference for further protection of the marine environment and subsequent experimental research.
