依据2008年5、8月对舟山渔场海域进行的水文环境和渔业资源状况的综合调查结果,阐述了舟山渔场海域表层氮磷的分布特征及其对浮游植物生长的限制状况。结果表明：氮磷含量总体上随着离岸距离的增大逐渐变小,呈现西高东低的分布趋势,无机氮、活性磷酸盐含量均表现为夏季低、春季高的特征。调查海域叶绿素a含量随氮磷的波动呈现明显的季节性和区域性变化,夏季明显高于春季。无机氮、活性磷酸盐与叶绿素a的分布呈负相关变化,春季调查海域表现为磷限制,夏季绝大多数调查海域为磷限制,只有调查海域最东部边缘表现为氮限制,这与一般海洋环境为氮限制的结论一致。

Based on the results of investigation of hydrological environment and fishery resource in the Zhoushan fishery ground in May and August,2008.This paper expounded the distribution of inorganic nitrogen and phosphate and their limitation on the growth of phytoplankton.The results showed that the content of inorganic nitrogen and phosphate was gradually diminishing with increasing of offshore distance,presenting west was high and east was low.The content of inorganic nitrogen and phosphate all manifested the features that it was higher in spring than in summer.The content of chlorophyll a with variety of inorganic nitrogen and phosphate differed obviously with season and region.And the content of chlorophyll a was higher in summer than in spring.There was a negative correlation between chlorophyll a and inorganic nitrogen and phosphate.The primary production in the Zhoushan fishery ground in spring might be limited by phosphate.Moreover,the primary production in a considerable portion of the Zhoushan fishery ground in summer might be limited by phosphate and only easternmost fishery ground might be limited by nitrogen which resembled general open marine systems.
