摘要
改进的邻体干扰模型为:Y=Y_m(1+CW ̄T) ̄(-1)。其中,Y_m为不存在邻体时的最大生物量,C、T为常数。
Multi-variate linear regression analysis showed that a close interrelationship existed between thesize of a plant and its distance to its neighbours and the nurnber of taller neighbours.Therefore,theneighbourhood interference index was redefined as W = H/(H_i.D_i),where H stands for the heightof focal plants,H,the height of ith neighbour,and Di the distance to ith neighbour.Finally,theinterference competition model was reformed as Y=Ym(1+cw ̄T) ̄(-1),where Y represents thebiomass of focal plants,Y_m the maximum biomass without any neighbours and c and T contants.
