| 摘 要： | This study showed how the daytime length in Jiaozhou Bay affected the water temperature, which in turn affected the phytoplankton growth when solar radiation was sufficient for phytoplankton photosynthesis. Jiaozhou Bay observation data collected from May 1991 to February 1994 were used to analyze the daytime length vs water temperature relationship. Our study showed that daytime length and the variation controlled the cycle of water temperature flunctuation. Should the cyclic variation curve of the daytime length be moved back for two months it would be superimposed with temperature change. The values of daytime length and temperature that calculated in the dynamical model of daytime length lag vs water temperature were consistent with observed values. The light radiation and daytime length in this model determined the photochemistry process and the enzymic catalysis process of phytoplankton photosynthesis. In addition, by considering the effect of the daytime length on water temperature and photosynthesis, we could comprehend the joint effect of daytime length, water temperature, and nutrients, on the spatiotemperal variation of primary production in Jiaozhou Bay.

| Abstract: | This study showed how the daytime length in Jiaozhou Bay affected the water temperature, which in turn affected the phytoplankton
growth when solar radiation was sufficient for phytoplankton photosynthesis. Jiaozhou Bay observation data collected from
May 1991 to February 1994 were used to analyze the daytime length vs water temperature relationship. Our study showed that
daytime length and the variation controlled the cycle of water temperature fluctuation. Should the cyclic variation curve
of the daytime length be moved back for two months it would be super-imposed with temperature change. The values of daytime
length and temperature that calculated in the dynamical model of daytime length lag vs water temperature were consistent with
observed values. The light radiation and daytime length in this model determined the photochemistry process and the enzymic
catalysis process of phytoplankton photosynthesis. In addition, by considering the effect of the daytime length on water temperature
and photosynthesis, we could comprehend the joint effect of daytime length, water temperature, and nutrients, on the spatiotemporal
variation of primary production in Jiaozhou Bay.

Oceanic Administration. |
