| 摘 要： | 本文研究了桑沟湾养殖海域的水环境特征，并与１０年前的历史资料作了比较。该湾各种化学指标的垂直分布均匀；受大面积高密度养殖影响，该湾水动力状况与１０年前相比发生了明显变化，营养物质输送和海水自净能力降低；各种化学指标、初级生产力、营养状况及类型等平面分布和季节性变化都有更加显著的差异。在海带养殖期间，ＩＮ和ＩＮ／ＩＰ始终处于低水平，其季节变化明显受该湾初级生产力制约，故ＩＮ必然成为桑沟湾初级生产的限制因素。另外，海带养殖也加速了其养殖期间湾内水体中ＩＮ的物质循环速率。

| Abstract: | The water environmental features in Sanggou Bay are discussed and compared with data obtained 10 years ago. The vertical distribution of determined chemical and biological indices in the waters is well-distributed. Being affected by unlimitedly increasing aquaculture, the water dynomic condition has changed obviously in comparation with that of 10 years ago. Carrying capacity and self-purification of sea water decreases. The horizontal distribution and seasonal changes of chemical indices, nutritive situation and types, premary productivity differ greatly from those of 10 years ago. IN contents and IN/IP value are lower during kalp cultivation. Their seasonal changes are restricted by primary productivity. So, IN has become a limiting factor to the primary productivity. Aquaculture has also accelerated the circle rate of IN in the waters. |
