渤海水域叶绿素a的分布及初级生产力的估算
, PP. 90-98
Abstract:
1980-1981年在渤海90个测站上进行了浮游植物种类组成及数量变化、叶绿素含量、海面辐照度、海水光学参量以及海洋水文要素调查,还作了浮游植物光合作用率和同化系数的测定。绘出渤海水域各季节叶绿素a和初级生产力的平面分布图。渤海水域表层叶绿素a的平均值春季、夏季、秋季和冬季分别为1.04,0.69,1.27和0.64毫克/米3。初级生产力的测定采用叶绿素法。通过调查计算得出渤海初级生产力平均值:春季为357毫克碳/米2·日;夏季为171毫克碳/米2·日;秋季为305毫克碳/米2·日;冬季为88毫克碳/米2·日。渤海初级生产力的年平均量为90克碳/米2·年。整个水域全年有机碳生产量约为800万吨。
