Abstract: In the Huanghe River Delta, wetland communities were studied to determine their soil and vegetation characteristics at different sucessive stages. Fourwetland samples of Suaeda salsa(saline seepweed) community,Tamarix chinensis(tamarisk) community, Imperata cylindrica(white cogongrass) community and barren land were classified using a special-replacing-temporal method. An ANOVA with soil nutrient(total N, alkaline hydrolyzing N, quick-acting K and P) and organic mater(OM)variables from four sample plots with 0- 20 cm and 20- 40 cm soil and three replications, aswell as anANOVAof species diversity(D and H indexes) of four communities using a sampling design with 1 m 1 m plots, eight replications for herbage and 10 m 10 m plots, 5 replications for shrubswere analyzed. Results showed thatwith a reduction of soil salt in the wetlands, organic matters and total nitrogen increased significantly(P 0.05) as did alkaline hydrolyzingN and quick-acting P(P 0.05)。Among the different communities, the above nutrients were significantly different(P 0.05). The importance value(IV)for four communities of edificato was S. salsa(65.47%), T. chinensis(36.23%),and I. cylindrica(34.50%); for annual herbaceous plants was S. salsa(65.47%), T. chinensis(30.43%), and I. cylindrica(15.41%); and forperennial herbaceous plantswas S. salsa(19.90%), T. chinensis(33.33%), and I. cylindrica(79.67%). With succession, IV of edificato and annual herbaceous plants gradually decreased, whereas the IV of perennial herbaceous plants gradually increased. The species richness and plant diversity in an order was I. cylindrica community T. chinensis community S. salsa community. Therefore, soil and vegetation of wetland communities in different successive stages were different[Ch, 1 fig. 3 tab. 15 ref.]
