摘要
沉水植被修复是湖泊修复的一项重要手段,浅水型富营养化湖泊惠州西湖实施了沉水植被修复后,水质得到了显著改善。以细菌16sRNA基因通用引物进行PCR扩增后,采用变性梯度凝胶电泳(DGGE)技术对惠州西湖已修复和未修复的子湖浮游细菌多样性进行分析。结果显示,进行沉水植被修复的子湖中,细菌的Pielou和Shannon-Wiener指数都显著高于未修复的子湖。表明沉水植物修复不仅可以改善水质,同时还可以提高浮游细菌的多样性。
Restoration of submerged vegetation in shallow eutrophic lake is an important method of lake restoration.Some areas of Huizhou West Lake has been successfully restored by planting submerged plants,and the water has been significantly improved.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 were 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. This study indicates that submerged vegegtaion not only improve water quality, but also increase the diversity of bacterioplankton.
