| 摘 要： | 由于车由岛周海域水比较浅，上下层混合得比较充分，营养盐的垂直分布较均匀，但在水平方向上差别较大。各种营养盐受生物活动、降雨和陆地经流的影响，有明显的季节变化。活性磷、硝酸盐和亚硝酸盐的浓度在冬季最高，春季最低；氨氮和活性硅的浓度则相反，夏季最高，秋季最低。

| Abstract: | Because the water of the sea area adjacent to Cheyoudao is quite shallow and the waters in the surface layer and the bottom layer are mixed well,the vertical distributions of the various nutrients are quite homogeneous. But there are relatively great differences in their horizontal distributions. The nutrients have apparent seasonal variations owing to the influences of precipitation,runoff and biological activities. The concentrations of active phosphorus,nitrate and nitrite are highest in winter and lowest in spring. On the contrary,the concentrations of ammonium-nitrogen and active silicon are highest in summer and lowest in autumn. |
