| Abstract: | Movable sample plots were investigated in young stands of Phyllostachys pubescens established with seedling Stands structure factors, site factors, and management factors were measured. Soil samples were analysed in the nomal way. Datum were processed with multivariate succesive regression, principal component analysis (PCA) and cluater analysis. The factors of climate, site and stands structure with main importance effecting bamboo growth were revealed. Theout-put classes of bamboo timber were divided into three types and management measures were discussed respectively. |
