The impact of submerged vegetation restoration on the structure of bacterioplankton in Huizhou West Lake
|
Abstract:
Restoration of submerged vegetation in shallow eutrophic lake is an important method of lake restoration, Some areas of Huizhou West Lake has been restored successfully by planting submerged plants, and the water has been improved significantly. In order to study the impact of the submerged vegetation on bacterioplankton, bacterioplankton community composition was investigated in restored area and unrestored area in Huizhou West Lake. The diversity of bacterioplankton of the restored area and unrestored area was analyzed by denaturing gradient gel electrophoresis (DGGE), using the bacterial 16sRNA gene universal primer to do the polymerase chain reaction. The results showed that Pielou index and Shannon-Wiener index of the restored area were significantly higher than that of the unrestored area. The study indicated that submerged vegegtaion can not only improve water quality, but also can increase the diversity of bacterioplankton.
