The distribution characteristics of bacterioplankton in the Dapeng Bay were investigated by fluorescence micros-copy over an annual cycle. The relationships of bacterial abundance with temperature, dissolved oxygen, chlorophyll a, am-monium salt, nitrate, and phosphate were discussed. The results show that the bacterioplankton abundance throughout the year varied from 1.40×108 cells L?1 to 24.43×108 cells L?1. The level of bacteria abundance in each season was as follows: sum-mer>spring>autumn>winter. The horizontal distribution of bacterioplankton showed a higher inshore, gradually reduced off-shore, and a gradually reducing characteristic from the top to the bay mouth. Excluding summer, temperature had a significant correlation with bacterioplankton abundance (P<0.05). Bacterioplankton abundance and dissolved oxygen were negatively correlated throughout the year. Excluding spring, chlorophyll-a had a significant correlation with bacterioplankton abundance (P<0.01) and played a significant role in the control of bacterioplankton. Among the inorganic nutrients, ammonia and phos-phate salt were the dominant factors in controlling bacterioplankton; both had a significant correlation with bacterioplankton abundance (P<0.01). In winter, nitrate regulated the bacterioplankton.
