The results showed as follows: Three kinds of prawnponds wetland have good water quality, transparency 40 ~ 80 cm, pH value 7.8 ~ 8.6, water temperatures 21~28℃, and M/D value 1-4, dissolved oxygen was rich, and the water type belongs to Cl- - Na+ and medium-sized soft water or hard water and most one. Take Cl and (K+ + Na+ ) as the principal composition in anion and cation of water chemistry, respectively, the compositions of water chemical ions and water type were the same with the natural seawater. The contents of major nutrient elements were high, the content of TN in prawn pond of desalination was 0.693 -5.61 mg/L, one by seawater and seawater-freshwater were 0. 101 ~ 0.215 mg/L, and the average content of phosphate was lower. The composition proportion of nitriqen and phosphate were not balance on three kinds of prawn ponds waters. N/P value was 2.6-3.2 in prawn ponds of the seawater and the seawater-freshwater, and was 14.4 - 53 .3 in prawn ponds waters of the desalination. In prawn ponds of the seawater, the seawater-freshwater, the average biomass of phytoplankton was 3.84×106 2.89×107 cells/L, the average biomass of zooplankton and bacteria-plankton were 120.3 ~ 465. 5/L and 3.23×104 - 6.25×104/L, respectively. There were changes of the physic-chemical characteristics of different waters of prawn ponds, but changes were not occur red markedly. The water quality changes of different types of prawn ponds and major physic-chemical factors, nutrient state and the correlation to prawn culture were discussed and assessed. Possibility of transplanting prawn was preliminary studied in carbonate saline-alkaline waters.
