In this study, the relation between the structural changes of bamboo forests and the distances from the bamboo forests to the nearest residential areas was investigated in order to evaluate the relationship between human activities and the structural changes of the bamboo forests over two time periods. The results obtained from 1968 to 1978 demonstrated that the percentage of bamboo forests having a residential area within a radius of 250 m was higher in Group B, in which the area of the bamboo forests increased over the time, than in Group A, in which the area of the bamboo forests increased over the time. This indicated that the expansion of the bamboo forests was restricted. On the other hand, the results obtained from 1978 to 1992 showed that the percentage of bamboo forests having a residential area within a radius of 50 or 100 m was slightly higher in Group B than in Group A, and that of bamboo forests having a residential area within a radius of 250 m was lower in Group B than in Group A. These results indicated that bamboo forests were poorly managed at a 250-m distance from the residential areas, and then the poor management has gradually come closer to the residential areas, resulting in the expansion of the bamboo forests.
