| Abstract: |
| A simulated wetland system was set up in a greenhouse，the growth traits and physiological
characteristics of Spartina alterniflora under different salinity（ 10‰，20‰ and 30‰） were compared to study the
adaptability of S. alterniflora to salt leaching environment. Results showed that there were significant differences
from different salinity treatments with plant height，basal stem，leaf SPAD，chlorophyll content，nitrogen content
and mortality of S. alterniflora. With the increase of salt concentration，plant height and stem decreased，leaf of
S. alterniflora increased，leaf chlorophyll content and SPAD increased. The highest salinity（ 30‰） significantly
decreased the dry weight biomass of S. alterniflora. The survival rate of S. alterniflora was 55.16% in salinity 20‰，
and the survival rate of S. alterniflora was the lowest（ 43.22%） in salinity 30‰. S. alterniflora had a relatively high
adaptability to salinity，but high salinity had certain restrictions to the plant growth. |
