摘要
据1990年11月至1991年8月间调查资料,提出刘公岛水域内叶绿素-a含量的时空分布和初级生产力的分布与变化。指出此分布与该水域温度和营养盐含量密切相关。叶绿素-a含量以春季最高,冬季次之,秋季稍低,夏季最低。年变幅为0.21~2.45mg/m3,年平均值为1.02mg/m3。初级生产力以夏季最高,春季次之,秋季略低,冬季最低,年变幅为33.40~512.72mg·c/m2·d,年平均值为181.15mg·c/m2·d。
We present the time space distributions of the chl-a concentration as well as the distributions and variances of the primary productivity in the Liugong Island waters, from November, 1990 through August, 1991. The distribution of chl - a concentration was closely correlated with the temperature and the nutrient concentration. The concentration of chl-a was highest in spring, higher in winter, lower in autumn, and lowest in summer, the annaul variation range was 0. 21 -2. 45mg/m3,and the annual mean was 1. 02mg/m3. The primary productivty was highest in summer, higher in spring, lower in autumn, and lowest in winter, its annual variation range was 33. 40~521. 72mg. c/m2. d ) and the annual mean was 181. 15mg. c/m2. d.
