Site Classification and Site Quality Evaluation of Dendrocalamus farinosus in Sichuan

Dendrocalamus farinosus is one of most important bamboos in Sichuan.In this study,an experiement on site classification and site quality evaluation of Dendrocalamus farinosus was conducted by use of the comprehensive survey.One site area,two site regions,four site sub-regions and forty-five site types were divided in the study.The result of site evaluation showed that altitude,soil thickness,slope position and slope gradient were main in fluential factors on the bamboo growth.It was also found that there was no obvious correlation between slope aspect and bamboo growth.As a consequence,a conclusion could be drawn that deep soil (>60cm),middle-low altitude(<800m),middle-low slope position and gentle slope gradient(<25°)should be considered before forestation of this bamboo species.
