| 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。

| Abstract: | 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. |
