摘要: |
文章根据2011年5月和8月两个航次的调查资料,分析东山湾营养盐含量、分布、结构特征及其关键影响因子,并探讨了营养盐对浮游植物的限制情况。结果表明,除活性硅酸盐,夏季活性磷酸盐、总磷、无机氮和总氮含量均高于春季;春、夏活性硅酸盐、活性磷酸盐、总磷、无机氮和总氮分布整体呈现为漳江入海口和八尺门海域含量较高,其含量、分布主要受漳江陆源径流的影响,其次为浮游植物的消长;春季东山湾海域水体中N/P、Si/N 、Si/P和TN/TP平均比值分别为64.3、9.1、583.1和13.4,夏季平均比值有所降低,分别为28.3、4.9 、155.3和13.3;春季N/P、Si/N、Si/P 、TN/TP高值区均位于湾口位置,而夏季N/P、Si/N、Si/P、TN/TP整体呈现以八尺门邻近海域为中心、自西向东扩散;2011年春、夏季均存在磷限制现象,春季尤为严重,磷限制的站位比例为83.3%。 |

Abstract: |
The concentration and spatial distribution of nutrients,nutrient structure characteristics,the key influential factors and their restrictive effect on phytoplankton in the Dongshan Bay were studied on the basis of two cruises in May and August.The results showed that except DSi,the concentration of SRP,TP,DIN and TN were higher in summer and lower in spring.The concentration of DSi,SRP,TP,DIN and TN were mainly affected by the Zhangjiang runoff,followed by phytoplankton growth,which appeared an overall trend of higher in Zhangjiang Estuary and Bachimen areas in spring and summer.The average ratio of N/P,Si/N,Si/P and TN/TP were 643,9.1,583.1 and 13.4 in the waters of Dongshan Bay in spring,and summer average ratio decreased,respectively 28.3,4.9,155.3 and 13.3.High areas of N/P,Si/N,Si/P and TN/TP were located in the bay mouth in spring,but N/P,Si/N,Si/P and TN/TP values appeared an overall trend of Bachimen area as the center,high west and low east in summer.In spring and summer of 2011,there were all P limitation,and 83.3% of the stations presented P limitation which was more serious in spring. |
