黄海海区的叶绿素α和初级生产力

Chlorophyll a and Primary Productivity in the Yellow Sea

本文是对70年代末以来我国在黄海西部海区进行的叶绿素a及初级生产力调查和研究的综述。内容包括叶绿素a水平分布,垂直分布。粒径大小分级,初级生产力的季节变化,山东近岸初级生产力,浮游植物量子产值及光利用效率,初级生产力模式及利用遥感法估算叶绿素a等。结果显示,黄海初级生产力有明显季节变化,春季最高,冬季最低;高生产力区位于长江口外海及黄海北部;大部份海区年平均值在200～500mg·m^(-2)。d^(-1)(以碳计)之间,平均值在425mg·m^(-2)·d^(-1)左右。

A review and summary was made of the investigation and studies on chlorophyll a and primary productivity conducted by the Chinese scientists in the Yellow Sea since the 70's. It includes the horizontal and vertical distribution of chl a,size fractionation,seasonal variation of primary productivity,the primary productivity along the coastal waters of Shandong province,the quantum yields and light utilization efficiency of phytoplankton, the models of primary productivity and estimation of chl a by remote sensing. The results show that there is a clear seasonal pattern of variation of the primary production in the Yellow Sea with a maximum value in spring and a minimum in winter. The high productivity areas are located in the waters off the estuary of the Yangtze River and the Northern Yellow Sea. For most areas of the Yellow Sea,the annual average primary productivity was 200～500mg. m^(-2). d^(-1) (Carbon)and the average value for the whole area was about 425mg. m^(-2). d^(-1).
