Abstract:Spartina alterniflora, an introduced species vegetating on inter-tidal flats from the eastern coast of the United States, has become a hot topic focusing on its invasion to local species in the coastal zone of China. Impacts of S. alterniflora to inter-tidal soil microbiological properties and soil microbial diversity in Jiangsu coastland are discussed in the paper by the control of those living in barren tidal flats. The soil microbial biomass in inter-tidal zone increases more with the growth of S. altern...
