| Abstract: |
| A three-dimension ecological dynamic model was established to numerically study the relationship of HAB and environmental conditions. The numerical experiments showed that the growth of diatom, the dominant HAB specie, was mainly restricted by phosphate and silicate. If the concentrations of phosphate and silicate reach 17-25 μg/L and 300-375 μg/L respectively, the water is in a state of eutrophication. When phosphate and silicate up to 26-32 μg/L and 350-500 μg/L respectively, HAB could be induced. The major regions of HAB occurrence are Jiaozhou Bay mouth, coastal bays, and coastal area from Maidao to Shilaoren. To avoid HAB occurrence, concentration of phosphate and silicate should not exceed 17-20 μg/L and 300 μg/L as a whole. Reasonable control of pollutant discharge is a key point to prevent water eutrophication and HAB occurrence. |
