To compare the purifying effect of wetland systems of Sonneratia apetala and Phragmites communis,nitrogen(N) and phosphorus(P) contents,and relevant indicators in water,soil and plant samples were determined in each season.The results show that water pollution in the two systems was serious in autumn and winter.The purifying effects of S.apetala on N and P were better than of P.communis in water,especially in winter.Soil adsorption on N and P was stronger in summer than in winter.In summer,N content in S.apetala soil was lower than that in P.communis soil,while it was opposite in winter.P adsorption in S.apetala soil was also stronger than in P.communis soil.No matter in winter or in summer,purification effect of S.apetala wetland system was better than that of P.communis system.Enrichment effect of P.communis on N was stronger than on P,while S.apetala had a relatively obvious enrichment effect on P.
