This paper is to study the effect of the waterlogging on biomass allocation and allometric pattern of rhizome and root system in Phyllostachys rivalis. The biomass of 1-year-old bamboo rhizome and rootwas investigated in a pot experiment with treatments of artificial irrigation and waterlogging for three and six months. The response, adaptative strategy of biomass allocation in rhizome and root of Ph. rivalis under long-term waterlogging conditions were analyzed. The results showed that the growth of roots was inhibited under waterlogging conditions and the allocation proportion of Ph. rivalis biomass was in the order of rhizome > root. Compared to the CK, the biomass of root and the ratio of root biomass to total biomass decreased significantly, the ratio of rhizome biomass to total biomass increased in the TR. It would grow lots of rhizome and root with the extension of waterlogging time and the biomass increased significantly. But no obvious impact of waterlogging on the proportion of rhizome biomass, root
