Abstract

Abstract:

Surface water samples were collected monthly for a total of 12 months from three stations in Sanya. Their virioplankton and bacterioplankton abundances were measured by flow cytometry and their correlationships with evnironmental factors were also studied. The results show that the abundance of virioplankton (7.63×10⁶viruses·mL^-1on average) was higher than bacterioplankton abundance (1.52×10⁶cells·mL^-1on average). Virioplankton and bacterioplankton abundances in the Estuary of Sanya River were significantly different from those on the west side of the Luhuitou Peninsula and Xiaodonghai. The highest virioplankton and bacterioplankton abundances appeared in the Estuary of Sanya River, with obvious seasonal variation(P<0.01). The abundances of virioplankton and bacterioplankton were significantly positively correlated (r = 0.800, P<0.01); and chlorophyll a, N nutrients (NO- 2, NO- 2+NO- 3, NH+ 4) are their key ecological factors (P < 0.01).

Key words: Sanya, virioplankton, bacterioplankton, flow cytometry
