Abstract: The present paper analyzed the spatial and temporal distribution of bacterial community from Hejia village river stretch in Hailang river.The results was concluded that the bacteria isolated from above belonged to five bacterial genera,among which Micrococcus was the preponderant genus and followed by Pseudomonas and zoogloea.For the time distribution,the number of bacterial communities from water samples got the highest value in May 2009 and the minimum in January 2010,whereas the number of bacterial communities from soil samples got the highest value in May 2009 and the minimum in July 2009.For the spatial distribution,the total number of bacterial communities from both water and soil samples in 8,9 and 10 points was higher than the others,but the bacterial genera in various points was not significantly different.

Key words: Hailang river, bacterial communities, spatial and temporal distribution
