摘　　要：探索黄河三角洲潮沟浮游生物群落结构特征,对于评估潮滩湿地生态系统的健康状况具有重要意义。2021年4月,在黄河三角洲南部和北部潮滩湿地分别选取典型潮沟网络,开展浮游生物实地调查,分析浮游植物和浮游动物的分布特征及其影响因素。研究结果表明,春季黄河三角洲潮沟网络内浮游植物共有45种,隶属于3门36属,以硅藻门和甲藻门为主;浮游动物共有22种,以桡足类和浮游幼体为主;多样性分析表明,潮沟内浮游植物和浮游动物的多样性、均匀度和丰富度均处于较高水平;同步性分析表明,与浮游植物相比,潮沟网络内浮游动物的同步性较高;浮游生物群落的多样性与各水环境因子均不相关,而浮游生物密度与水体电阻率和氧化还原电位显著正相关,与盐度、比电导度和总溶解固体质量浓度显著负相关。It is of great significance to explore the characteristics of plankton community structure in the tidal channels of the Yellow River Delta for assessing the ecosystem health of the tidal flat wetlands.In April 2021,two tidal channel networks affected by different human activities in the Yellow River Delta were selected to carry out the field survey of plankton,and the distribution characteristics and influencing factors of phyto-plankton and zooplankton were analyzed.The results showed that there were 45 species of phytoplankton in the tidal channel network of the Yellow River Delta,belonging to 3 phyla and 36 genera,among which the dia-toms and dinoflagellates were predominant.There were 22 species of zooplankton,mainly belong to copepods and larva.The diversity analysis showed that the diversity,evenness and abundance of phytoplankton and zoo-plankton were at a high level.The synchronization analysis showed that the zooplankton in the tidal channel network had higher synchronization than phytoplankton.The correlation analysis showed that plankton com-munity diversity was not significantly correlated with water environmental factors,but the community bioden-sity was positively correlated with electrical resistivity and redox potential,and negatively correlated with sa-linity,specific conductance and total dissolved solids.
