Abstract: In order to evaluate the effects of Amomum tsao-ko planting on forest structure and the distribution pattern of the Trachypithecus shortridgei populations, community interviews and field studies were conducted to systematically investigate the planting areas of Amomum tsao-ko, the present situation of the Amomum tsao-ko planting, the current distribution pattern of the Trachypithecus
shortridgei populations and the forest structure via community and field investigating in the Trachypithecus shortridgei's habitat. The
results showed that the Amomum tsao-ko planting area still showed a rapid rising trend; the population distribution of Trachypithecus
shortridgei was sporadic small groups, the distribution points increased to 45, and the average number of individuals in a single
population had fallen by 5 individuals; there were significant differences in forest structure between the planting area and the nonplanting area, such as the height of trees in the planting area was significantly higher than that in the non-planting area, the arbor
canopy connectivity distance was increasing, and the canopy projection surface was decreased. At present, the planting area of Amomum tsao-ko has been increasing speedily, which has affected the forest structure and the distribution pattern of Trachypithecus shortridgei.

Key words: Amomum tsao-ko planting, forest structure, Trachypithecus shortridgei, population distribution pattern, sustainable
