For the manual and mechanical operations applied on the thinning of Phyllostachys makinoi bamboo stand in Miaoli county, the bamboo growth and biomass were investigated and estimated before logging. The experimental plots were set to realize the change of biodiversity and soil surface under different types of operations. The results displayed that the mechanical operations took less impacts on biodiversity an soil surface. On the other hand, for the operational conditions of the study, the mechanical operation was more beneficial for the 90m operational depth.
On the aspects of the factors of efficiency for cutting and logging operations, the slope and logging distances were the factors separately.
