| 中文摘要 |
| 以九龙江河口湾区为研究区域探寻受人为干扰严重的河口湾区DMS排放规律.2001年冬季采样调查发现在九龙江河口和湾口区叶绿素、盐度和营养盐等环境因子呈现出区域差异,海水DMS也存在明显的空间分布特征,平均浓度分别为101.0和242.1 ng·L-1.随着海水盐度从低到高,DMS浓度出现先降低后升高的现象,DMS高值出现在九龙江最大浑浊带的河口峰面处.

| 英文摘要 |
| Cruise investigation of dimethylsulfide (DMS) emission in estuarine areas, heavily disturbed by human activities, was carried out in the winter of 2001 in Jiulong Jiang Estuary. The concentrations of chlorophyll, salinity and nutrients showed evidently spatial distribution in Jiulong Jiang Estuary, so did DMS concentrations in surface water. The average of seawater DMS was 101.0 and 242.1 ng·L-1 in river mouth area and gulf area, respectively. DMS concentrations decreased first with the increase of seawater salinity and then increased. The highest DMS concentration occurred at river plume front of maximum turbidity zone of the estuary. |
