Abstract
Plant group classification relation to soil environmental characteristics was monitored in Hangzhou Bay coastal wetland, China. 18 taxa, belonging to 17 genus and 7 family were recorded, and classified into five groups by TWINSPAN viz A, Scirpus mariqueter group, B, Spartina alterniflora group, C, Phragmites communis group, D, Tamarix chinensis - P. communis group, and E, Salix matsudana - Imperata cylindrica group, respectively. Soil salinity and moisture in group A, B and C were significantly higher than group D, E, while higher pH values was found in group E, A and B. From the intra-set correlations of the soil factors with the first 2 axes of DCCA, it can be noted that DCCA axis 1, was positively correlated with altitude and negatively with soil salinity and moisture, represented soil salinity and moisture gradient. Axis 2 of the DCCA was clearly negatively correlated to soil pH, and called as soil pH gradient.
