Abstract

Abstract

On the basis of the four cruises in the Sany a Bay, a typical tropical coral reef bay of China, located in the northern part of South China Sea in the south coast of Hainan Island, in January(winter), April(spring), July(summer) and October(autumn) 2005, the spatial-temporal distribution patterns of phytoplankt on and bacteria biomass were studied. The relationships between their biomass and environmental factors, suchas temperature, DIN, phosphorus, DO and BOD5, were also analyzed. The results showed that the mean chlorophyll a was(2.48±2.97) mg/m³,and the mean phytoplankt on biomass(PB, C) was(124.2±148.3) mg/m³ in the Sany a Bay in 2005, with highest value in autumn. The vertical distribution of PB was shown as the surface> bottom, except in summer. The annual mean bacterioplankton abundance was 6.90±2.95) ×10⁸ells/dm³,and the mean bacterioplankt on biomass(BB, C) was,with highest value appeared in summer, and winter, spring, autumn, in turn. The BB at the surface layer was higher than bottom layer in all four seasons. The distribution of PB and BB at the surface and bottom layers in almost demonstrated the same pattern, which showed that the highest biomass appeared in the estuary of the Sanya River, and their abundance gradually declined off shore. The distribution feature mainly resulted from the terrestrial input from the Sany a River and invasion by the off shore oceanic sea water. In the inorganic nutrients, DIN was the leading factor of regulating PB and BB. Temperature almost had no influence on them in the tropical Sanya Bay, with temperature higher than 22℃. The correlation was significant between BB and PB(P< 0.01), the ratio of BB to PB ranged from 0.06 to 0.15(average value was 0.12). Primary production was an important factor in controlling the distribution of bacterioplankt on.
