【Abstract】 The study on the structure and the spatial pattern of S. superba population was carried out at Mt.Wuvi,with the method of spatial sere substituting for time sere. On the basis of a census of all individu als of S. superba population at different successional stages,the size structure,the spatial pattern of the popualtion and their dynamics were described. In the early period after S. saperba population invaded the Pinus taiwanensis forest,the size structure of popualtion was characterized by growing time,while the spatial pattern of population showed randon type. During the process of development form P. taiwa- neasis forest to mature forest dominated by S. superba and C. eyei the size structure of the population tended to stationary,then it tended to mature and senescence. In the meantime,the spatial pattern tended to contagious type. In the stages of the mature forest,the structure of S. superba population had a process of fluctuation accompanying the regeneration or rehabilitation through forest gaps,but the spatia]pattern also followed contagious. According to the result above studied,the dynamic mechanism of S.superba population had been discussed.
