On the subtropical mountain swards, the effect of cutting periodicity on energy allocation, module density, number of branches and branching angle of T. repens were significant, With cutting periodicity raised, the energy allocation of stolon increased steadly , the caloric content of unit stolon dropped gradually , and the changing pattern of leaf density, stem density, branch number and internode's length was from low to high, and then to low. The branching intensity of T. repens ranged from 15 to 23.7 branchescntdotm-2, and branching angle raried from 49.5degree to 60.2degree while the cutting periodicity differed.
