Abstract: This work was carried out in Xiamen Port from January, 1986 to December 1995. The community structure were: Suncus murinus + Mus musculus + Rattus norvegicus + R.flavipectus + R.rattoides. Theed belongy to 5 species, 3 genus, 2 families and 2 orders. The community structure of the four types of Biotope were as follows: Container and offices-dwelling, Biotopes:Suncus murinus + R.norvegicus + Mus musculus + R. flavipectus; Barn and storehouses Biotopes:Suncus murinus + Mus musculus + R.norvegicus + R. flavipectus. The capture rates were distmctly different in different Biotopes. The highest rate was in office- dwelling Biotopes. The yearly seasonal fluctuation of the popula tion looked like“山”in 1995. It was the highest from August to September. The capture rates of R. flavipectus and R. rattoides were both zero. There has been obvious succession of rodents community in the past ten years. The dominant species of community were: Suncus murinus→R. norvegicus→Mus musculus→Suncus murinus.
