Abstract— Every year since 2003, algae bloom has broken out in the influence the growth velocity, abundance and species of the
branch bay of the Three Gorges Reservoir in Spring. The area algae (Fairchild, 1985; Wang Qi hua et al, 1997 and 1998;
affected by the algae bloom is often subject to disturbance which ZHANG Dongpeng, 2000). When the ratio rises from
resulting from shipping, storm-runoff event, water conservancy : mg/L to : mg/L, the benthic diatom biomass
scheduling and wind-wave etc. With its focus on effect of the increases abruptly (Austin A P, 1990). The existence of the
disturbances on algae growth, this paper took the Xiangxi River Bay nutrients of Fe and silicon has an impact on the growth of
as an example. Water was sampled in the duration of algae bloom algae. The experiment results from the lab showed the growth
pared the chlorophyll-a concentration variation with time velocity of the benthic diatom was fastest when Fe ion
under bined conditions of disturbance, temperature and light concentration was mg/L and silicate mg/L (de Castro
through lab experiment, on basis of which the r
