| 摘要: |
| 在北海湾近岸内湾,设9个测站,选取4个有代表性的季度月,即1998年10月(秋季)和1999年1月(冬季)、4月(春季)、8月(夏季),采集海水样品分析测定悬浮颗粒物(SS),同时还同步测定水温、盐度、pH值、化学需氧量(COD)、透明度、叶绿素a及5种不同形态的氮、磷和溶解性硅,研究北海湾悬浮颗粒物的分布特征及其与环境因子之间的关系。结果表明,北海湾悬浮颗粒物含量具有春季较高,秋季次之,冬夏季较低的分布特点。在陆源影响较小的秋冬季节,悬浮颗粒物与环境因子之间的关系均不显著;而在陆源影响较大的春夏季节,悬浮颗粒物在与盐度、透明度呈显著负相关的同时,与COD和不同形态的氮、磷亦具有显著的正相关关系。 |

| Abstract: |
| Based on the investigation in four typical seasons from October 1998 to August 1999,in Beihai Bay,the migration and distribution characteristics of the suspended particles and its relationship to environmental factors were studied.The investigation was carried out at the shore area of inner bay of Beihai,with 9 sample stations,taking sea-water for analyzing SS,and simultaneously measuring water teaperature,salinity,pH value,COD,transparency chlorophyl a,and 5 different types of nitrogen and phosphor and soluble silicon.The results show that the amount of the suspended particles is the highest in Spring,higher in Autumn,lowest in Winter and Summer.The correlation analysis showed that there is no evident relation between the suspended particles and the environmental factors during Autumn and Winter in which the land-source effect was less important;while in Spring and Summer,the suspended particles were evidently negative-correlated to salinity and transparency,and positive-correlated to COD,nitrogen and phosphor in different types. |
