Abstract: The species characteristics in the different communities of wetland plant with human disturbance were studied from their families,genera,life-form and ecology-form in Wutai Mountains.The results showed that the number of genera and species was much less in the area with serious disturbance than that with little disturbance.The appearing frequency of species in the families of Leguminosae,Labiatae,Compositae,Polygonaceae and Poaceae was the most,and they belonged to the endurance species.Moreover,single family,genera and species often appear.As of the ecological response for species flora to humban disturbance,the component in the temperate zone distributed widely,however,those in the entire world and the tropical zone were poor.The flora trended to be single with the increasing disturbance.Except for area covered by Comm.Arte?misia japonica,as human disturbance was increasing,the proportion of chamaephytes was decreasing gradually,and that of therophytes was increasing.With the disturbance increasing,the proportion of hygrophytes was increasing gradually,and those of xerophytes,middle-xerophytes,xero-middlephytes and mesophytes trended to decrease.
