With batch culture experiments in field and laboratory, the ecological effect of No. 0 diesel water accommodated fraction on marine algae was studied. A growth model of marine algae under grazing pressure and a model of growth effect on marine algae with different doses No.0 diesel water accommodated fraction were proposed. Based on the model and experiments, the growth effect of No.0 diesel water accommodated fraction on marine algae was studied. The results show that, the growth model of marine algae under grazing pressure is more suited for the marine ecological system than Logistic model. And the final biomass (B(f)) of marine algae with different doses No.0 diesel water accommodated fraction was calculated by the model with none-linear fitting software. The results also show that, under the field and laboratory conditions, lower doses No.0 diesel water accommodated fraction promotes the growth of marine algae, and the most promoting ratio are 180% and 120% respectively, however, higher doses hardly promotes but bates the growth of marine algae.
