This paper dealt with Phragmites australis and Spartina alterniflora growned in the Shanyutan Wetland of Min River Estuarine, and analyzed 36 corresponding soil profiles, in order to reveal the distributed characteristic of the ash content of them and analyze influencing factors. The results showed that the differences of ash content of various organs were obvious,and the averaged value of each modules ash content of Phragmites australis were bigger than that of Spartina altemiflora;The vertical distribution of the soil ash content under the two plants were similar. The soil ash content in the wetland of Phragmites australis was slightly higher than that of the wetland of Spartina altemiflora. However, the differences of the soil ash content under the two plants were not remarkable;The soil ash content of the two kinds of wetlands and the soil organic carbon existed significant negative correlation ,and the correlation with the soil moisture was also obvious;Viewed from a single type of plant, the soil ash content of Spartina altemiflora wetland was greatly related to the bulk density, the carbon content, the moisture and the salinity, and the soil ash content of Phragmites australis wetland was greatly related to pH.
