摘要
本文以2002年辽东湾北部海区的调查数据为主,参考部分2000~2003年的数据,对辽东湾北部海区的初级生产力进行了估算,为了分析和讨论的方便,将辽东湾北部海区人为划分为三部分,东部的初级生产力最高,8月份平均为222 88mg·C/m2·d;中部区域初级生产力最低,10月份为46 39mg·C/m2·d。不同区域的初级生产力的差距较大;如单独估算20~30站位的初级生产力,则分别为:4月平均192 43mg·C/m2·d,6月482 69mg·C/m2·d,7月274 8mg·C/m2·d,9月252 52mg·C/m2·d,远远高于各站位的平均值。辽东湾北部海区的初级生产力具有明显的区域特征,与渔业资源关系密切。
The primary production was determined in the norther waters in Liaodong Bay from 2000 to 2003, and the factors affecting the primary production were discussed. The northern waters in Liaodong Bay was divided into 3 zones with the maximum in the east area (222.88 mg·C/m^2·d in August) and the minimum in the central area (46.39 mg·C/m^2·d in October). There was significant difference in primary production in different areas. The average primary production from Station 20 to Station 30 were 192.43, 482.69, 274.8,and 252.52 mg·C/m^2·d in April, June, July and September. The fishery resources were related with the primary production.
