[Effect of disturbance on growth of Microcystis aeruginosa in different nutrient levels].

The specific growth of Microcystis aeruginosa was studied under different nutrient levels and different disturbance in laboratory. It is shown that the algae get better growth under disturbance than stationary state in oligotrophic nutrient water, the specific growth rate can increase from 0.1 d(-1) to 0.

[Suspension-sedimentation of sediment and release amount of internal load in Lake Taihu affected by wind].

The water quality in Meiliang Bay of the Taihu Lake was totally tested five times in the four seasons. The suspension samples were obtained by using a sediment trap. The sediment settling flux and resuspended flux were calculated according to the observation data by using Gansith formula, and the relationships between these fluxes and wind speeds were established.
