| 摘 要： | 分析对比1959年、1982年、1998-2000年以及2007-2010年4个不同时期南黄海中部（34.25°~37.45°N，122.00°~124.00°E）浮游动物主要优势种中华哲水蚤（Calanus sinicus）、太平洋磷虾（Euphausia pacifica）和强壮箭虫（Sagitta crassa）数量时空变化及其与温度、盐度和太平洋年代际震荡指数（Pacific Decadal Oscillation，PDO）变动的关系。结果显示，温度可能对中华哲水蚤和太平洋磷虾数量分布影响较大；强壮箭虫则受盐度影响较大。PDO暖位相时期中华哲水蚤和太平洋磷虾数量显著低于冷位相时期，强壮箭虫则相反。中华哲水蚤和太平洋磷虾丰度与提前3个月PDO值呈显著正相关，强壮箭虫丰度仅与当月PDO值呈显著正相关。

| Abstract: | Based on historical data collected from the southern Yellow Sea (34.25°~37.45°N,122.00°~124.00°E) in 1959,1982,1998-2000 and 2007-2010,interannual temporal-spatial variations in abundance of the dominant zooplankton species Calanus sinicus,Sagitta crassa,Euphausia pacifica,were studied. Correlation analysis was carried out between the species abundance and environmental factors including temperature,salinity and the Pacific Decadal Oscillation (PDO). PDO index is an indicator of climate changes in the Pacific Ocean,north of 20° N. The periods of 1959 and 1982 were in warm phase with positive PDO values,while those of 1998-2000,2007-2010 were in cool phase with negative PDO value. Results showed that seasonal abundance distributions of C. sinicus,E. pacifica and S. crassa varied with seasons in different years. Temperature had more influences on the abundance distributions of C. sinicus and E. pacifica,while salinity showed more influences on S.crassa. C. sinicus and E. pacifica abundance were higher in cold year of 2007-2010,while S. crassa abundance were higher during warm years of 1959 and 1982. Monthly abundances of C. sinicus and E. pacifica were significant correlated with PDO index but lagged behind about 3 months,and those of S.crassa had significant correlation with concurrent month PDO index. |
