Abstract: | Using four continuous-flow indoor reservoir models, the combined effects of varying water inlet depth and sediment composition
on phytoplankton species composition and its succession pattern were studied.
Species which are known to bloom in eutrophicated reservoirs were dominant in the species succession in each tank. At any
one time, a step-like pattern was observed in the composition of the dominant species of each tank, wherein all the species
which appeared in a tank with a lower phosphorus concentration were included in the species composition of the tank with a
higher phosphorus concentration in an additive relationship. |
