浙江潮下带海域秋季初级生产力和叶绿素α的分市

Primary Production and Chlorophyll a during Autumn in the Coast Zone of Zhejiang

本文报道了1982年10月浙江潮下带(北纬27°10′—30°30′,东经122°30′以西)海域叶绿素α和初级生产力的分布。表层平均叶绿素α为1.85mg·m^(-3),10米层平均叶绿素α为1.91mg·m^(-3),略大于表层。文章比较了象山港、乐清湾、东山湾和渤海湾的叶绿素α分布状况。调查海区平均初级生产力为181.17mgC·m^(-2)·d^(-1)。其值低于浙江沿岸上升流海域。

The distribution of chlorophyll a and primary production were observed in the coast zone <27°10′-30°30′N, west to 122°30′E) of Zhejiang in Oct. 1982. The average value of chlorophyll a at surface and 10 meter layers were 1.85mg/m3 and 1.91 mg/m3 respectively. The contents of chlorophyll a at surface layer in Xiangshan Bay and Leqing Bay were compared, with that in Bohai Bay and Dongshan Bay (Fujian). The primary production was 181.17mgc·m-2 ·d-1 in the survey area. It was lower than that in the coastal upwelling area off Zhejiang coast.
