Abstract: In order to explore horizontal distribution characteristics of dominant zooplankton species in the Northwest Pacific Ocean,the dominant zooplankton was surveyed in zooplankton samples collected at 58 stations in the Northwest Pacific Ocean (146°-156°E,28°-35°N) in spring (March) 2019 and winter (December)2020.The relationship between dominant species and influencing factors of zooplankton were evaluated by Pearson correlation analysis and redundancy analysis.The results showed that 602 species (including unknown species) were identified during the two voyages,with more number of species in spring (456) than that in winter (386).Eleven dominant species were observed,including Pleuromammagracilis,Nannocalanusminor,Neocalanusgracilis and Sagittahexsaptera in the two seasons.Pearson correlation analysis revealed that latitude had a great influence on spring when there was significant or very significant negative correlation between latitude and Doliolumnationalis (P<0.05 or P<0.01).Mesocalanustenuicornis and Eudoxoidesspiralis were negatively correlated with latitude (P<0.05),and Calanusjashnovi was positively correlated with latitude (P<0.05).Lucicutiaflavicornis and S.hexsaptera were positively correlated with salinity in the winter survey area.Redundancy analysis (RDA) was consistent results with Pearson correlation analysis,with the latitude as main factor affecting the abundance of dominant species in spring (P<0.01),and salinity in winter (P<0.05).The results showed that the horizontal distribution of dominant species in winter and spring in the Northwest Pacific Ocean was controlled by different factors,which was the result of the comprehensive influence of many factors.The finding indicated that distribution of dominant species in spring was deeply affected by latitude,while salinity was the key factor in winter.
