廉州湾及其邻近水域初级生产力研究

A Study on the Primary Productivity of Lianzhou Bay Waters of Guangxi Province

１９９２～１９９３年，在对廉州湾及其邻近海域的环境调查中，首次对该海区叶绿素ａ与初级生产力进行了测定。获得叶绿素ａ的春季平均值为１．００ｍｇ·ｍ－３，秋季为０．２９ｍｇ·ｍ－３，初级生产力的平均值为３０１．５ｍｇ·ｍ－２·ｄ－１。文章对调查区初级生产力的分布特征及变化规律进行了探讨，并与北方沿海的初级生产力水平进行了比较。

The chlorophyll a and primary productivity of Lianzhou Bay and its adjacent waters were determined for the first time during the marine environment investigation from 1992￣1993.The average content of chlorophyll a was 1.00mg.m-3 in spring and 0.29mg.m-3 in autumn.The mean value of primary productivity was 301.5mg.m-2.d-1.The features of distribution and patterns of the variation of the primary productivity in this area were discussed in comparison with those in the northern coastal waters of China.
