【Abstract】 Environmental assimilative capacity to shrimps. rearing bay is estimated based on the rate of tidal exchange and the forecasting method of water quality in this paper. The results show that the mean concentration of COD is less than 3 mg/l and the total nitrogen concentration is less than. 0. 5 mg/l. Again they show that the increasing in envivronmental assimilative capacity with the decreasing concea- tration outside the bay.更多还原
