| Abstract: | The bacterial diversity investigation in the integrated system of constructed wetland and pond aquaculture was carried out during the period of Aug.～Oct.2009,using analytic method of DGGE(denatured gradient gel electrophoresis). The findings presented that temperature and DO of the culture ponds changed over the investigation period,and both bacterial density and diversity in the culture pond varied with change of the season;in addition,the levels of NH4+and TP in the control pond were significantly higher(p<0.05)than those in the recirculation ponds.Correlation analysis pertaining to the investigation revealed that bacterial diversity was remarkably and positively correlated with DO,but negatively with NH+4and TP.It was concluded that the pond-recirculation aquaculture could enhance bacterial diversity in the ponds thus the pond system became more stable ecologically. |
