摘　　要：2006年7月至8月现场调查了北部湾海域浮游植物叶绿素a含量的分布特征。结果表明:表层叶绿素a浓度范围0.14～7.89 mg/m3,平均1.13 mg/m3,并呈现自东向西、由近岸向湾中部逐渐递减的规律。水柱平均叶绿素a浓度达1.33 mg/m3。近岸区叶绿素a浓度垂直分布比较均匀,受温跃层的影响,深水区叶绿素a浓度在各层次存在明显差别。The distribution characteristics of chlorophyll a in the Beibu Gulf were investigated from July to August, 2006. Results showed that the surface chlorophyll a concentration of the surveyed area ranged from 0. 14 mg,/m^3 to 7. 89 mg,/m^3, averaged as 1. 13 mg,/m^3. The abundance of chlorophyll a decreased gradually from east to west and from the nearshore water area to the centre of the Gulf. The column average chlorophyll a concentration was about 1.33 mg./m^3. As a result of the thermocline, the chlorophyll a concentration of offshore water zone displayed a remarkable vertical variation, differed from the nearshore water zone.
