Chinese Abstract

分析了北太平洋鱿鱼渔场浮游植物种类组成、分布特点及其与环境、中心渔场的关系。初步鉴定出36属129种,种类组成以暖水性种类居多(占58.9%),虽然冷水性占种类比例较少(占10.9%),但在细胞数量上占明显优势(占总量的68.05%),出现热带、亚热带与亚寒带区系共存的局面;其平面分布不均,平均总量为54.60×10^3个/立方公尺;冷暖水系对浮游植物种类组成及数量分布均有显着的影响;中心渔场的形成与浮游植物高值区有着密切的关系。

English Abstract

129 species were identified, the species composition and distributing characteristics of phytoplankton in relation to environmental factors and central fishing ground were analyzed, The warm-water group was dominant (58.9%) in species composition, the proportion of cool-water group was quite low in species composition (10.9%), while it was obviously dominant in quantitative composition (68.05%), which implied that tropic zone, subtropic zone and subfrigid zone existed in this area meantime. The analyzing results show that the distribution of phytoplankton is not even during the investigation period, and the average concentration is 54.60×10^3 cell/m^3; the warm water and the cold water species have such a great influence on species composition and quantitative distribution of phytoplankton; and the form of central fishing ground is close related to high quantitative zone of phytoplankton.
