摘要
分别研究了2006年7月(夏季)和2007年1月(冬季)、5月(春季)、10月(秋季)黄海西北部海域浮游细菌生物量的分布特征,探讨了它们与温度、盐度和Chla含量之间的关系。结果表明,研究海区平均细菌生物量春、夏、秋和冬季分别为:41.083,8.34,16.68和6.20 mg/m3。4个季节表层细菌生物量分布均呈现出从辽东半岛近岸区域向外海逐渐降低的趋势。春、秋季除浮游植物Chla外各生态因子与细菌生物量之间均无显著性相关关系。夏、冬季与温度、盐度和Chla含量的相关性均不显著。
Based on the four cruises in the Northwest of the Yellow Sea in July 2006（summer）, January 2007（winter）, May 2007（spring） and October 2007（autumn）, the distribution patterns of bacterioplankton biomass were studied. The relationships between their biomass and environmental factors, such as temperature, salinity and chlorophyll a, were also analyzed. The results showed that the mean bacterial biomass（BB） was 41.08 mg/m^3, 8.34 mg/m^3, 16.68 mg/m^3 and 6.20mg/m^3 in spring, summer, autumn and winter, respectively. The distribution of BB in surface layer of different seasons almost demonstrated the same pattern, which showed that the higher biomass appeared in the Liaodong Peninsula inshore area and their biomass gradually declined offshore. There was no correlations between other environmental factors and the BB except for the surface chlorophyll a in spring and autumn. There were no correlations between the environmental factors and the BB in summer and winter.
