Abstract

Abstract

The occurrence of HAB is not a single biological and ecological problem.It is one under the control of marine dynamic environment.The numerical simulation for four cases manifests the important function of dynamic condition in the occurrence and the spread of HAB.Those cases are (1) the HAB real o ccurred in the Hongkong sea area in March to April of 1998.(2) Decreasing tidal amplitude for two-third only but without change for other parameters.(3) Changing the diffusion termonly but without change for other parameters.(4) With the marine construction, changing the environment topography only but without change for other parameters.Those simulation results manifest that the dynamic condition plays the function not only in the movement of materials but also in the occurrence of HAB.It could control the occurrence of HAB sometimes.
