Numeric and structural characteristics of wild Pteroceltis tatarinowii population in Daguisi national forest park in Hubei province were studied at two levels(single individuals and tillers), which include age structure, niche width, static life table and so on, and the development trend of the population was also discussed. The results showed that the average height of single individuals group was 10.26 m and that of tillers group was 17.01 m. The age structure indicated that the population was stable, and the single individuals group was increasing. However, the tillers group was declining. The regeneration of population mainly depended on regeneration of propagation. The niche breadth showed that the single individuals group could utilize more environment resources than the tillers group. From the static life table we knew that there was high mortality rate when young single individuals developed into adults, and the high mortality rate occurred on middleaged tillers. Therefore, some measures such as in situ auxiliary seed reproduction to increase germination rate of seed, and tending single seedlings into adults, and protecting middleaged tillers, must be adopted to regenerate and improve this population. These results could provide scientific guidance for the protection and reasonable utilization of P. tatarinowii
