| 摘 要： | 采用2015年10月采集的湛江港海域水体叶绿素a浓度、温度、盐度等参数,分析了秋季湛江港和入海口温盐结构及生态特征。研究结果表明,湛江港海域盐度的水平分布上由湾内往湾外逐渐递增,叶绿素a浓度由湾内往湾外逐渐递减,水深比较浅的区域水温较高,同时在航道入海口底层存在着“高盐低温低叶绿素”的相对稳定的冷水团结构。该水团的形成是由于湛江港出海口独特的地形构造促进区域性水体层化,同时底部水体透明度低,限制航道入海口区域底层的浮游植物的生长等因素所致。 |
| 关 键 词： | 湛江港海域 叶绿素a浓度 盐度 温度 冷水团 |

| Abstract: | The analysis on the thermohaline structure and ecological characteristics of the Zhanjiang Bay and its estuary in autumn was based on the investigations of Chl a concentration, salinity and water temperature in October 2015. The study showed that the horizontal distribution of the salinity in the Zhanjiang Bay increased gradually from inner bay to outside bay, the Chl a concentration decreased gradually from inner bay to outside bay, the water temperature is higher in shallow area, and that in the bottom of estuary there was a "high salinity, low temperature and low chlorophyll" relatively stable structure of cold water mass. The formation of the water mass was due to the unique terrain structure of estuary. This characteristic promotes the regional water stratification. At the same time, the low transparency of the bottom water body confine the growth of phytoplankton at the bottom of estuary. |
| Keywords: | Zhanjiang Bay temperature salinity Chl a concentration cold water mass |
