After 5 years' management,the structure and composition of Pleioblastus grass planting pattern have changed.The model of Pleioblastus grass planted before have became to be the single and pure Pleioblastns stand or the pure grass lands for the reasons of the model itself and the management willing of peasants.After that, the pure grass land on the slope can't reach the goal of water and soil conservation in the engineering of converting farmland to fore,st,and need to be improved.The ecological and economic benefits of pure Pleioblastus stand are better.This planting model may be only fit to the lands for the first 3 years,or the technology of grass and Pleioblastus's plot mixed structure need to be studied more in the future.
