Algae Growth under Combined Conditions of Disturbance, Temperature and Light

Every year since 2003, algae bloom has broken out in the branch bay of the Three Gorges Reservoir in Spring. The area affected by the algae bloom is often subject to disturbance which resulting from shipping, storm-runoff event, water conservancy scheduling and wind-wave etc. With its focus on effect of the disturbances on algae growth, this paper took the Xiangxi River Bay as an example. Water was sampled in the duration of algae bloom and compared the chlorophyll-a concentration variation with time under the combined conditions of disturbance, temperature and light through lab experiment, on basis of which the rule of algae growth and the probability of controlling the algae bloom by disturbing the water body was analyzed.
