Abstract

Through analysis of the size-fractionated chlorophyll-a contents in the remedied part, control part and non-remedied part in Suining Tributary, this paper discussed the effect of bioremediation to all size-fractionated chlorophyll-a contents. The averaged Chlorophy-a content of nano-plus pico-phytoplankton made up 85.232%, 92.402%, 95.205% of the total, respectively for the remedied, control and non-remedied part. Among these, the nano fraction alone made up 78.460%, 87.943%, 87.211%, respectively. Nano-phytoplankton contributed most to the total biomass of Chl a. Its average contribution was 84.538% to the whole tributary, whereas net-phytoplankton contribued only 9.054%. Nano- and pico-phytoplankton was most sensitive to the test eco-remedy. The remedy reduced the relative biomass of net-phytoplankton, and increased the relative biomass of Pico-enhance. The relative biomass of nano- and ultra-phytoplankton fraction was little effected.
