Abstract: The ammonia nitrogen,nitrite nitrogen,nitrate nitrogen,inorganic phosphorus,and microorganisms(Vibrio,total heterotrophic bacteria) in farming area and non-farming area in the period from December 2013 to October 2014 were determined to observe the annual changes in water quality and microorganism in tidal flats farming areas where Babylonia areolata was farmed. The results showed the concentrations of ammonia nitrogen,nitrite nitrogen and nitrate nitrogen had the peak values during the months from March to May. The peak value of inorganic phosphorus appeared in October. However,higher concentrations of Vibrio were detected from May to October. The water quality and microorganism parameters in the B. areolate farming area fluctuated,and no obvious difference was found in all the parameters,except ammonia nitrogen between the farming and non-farming areas. The results indicated B. areolata farming did not cause an obvious impact on sea water quality factors and microbial communities under the conditions of current culture area( 18 ha) and culture density 300 shells/sq. m.
