内村(1973)根据以3/2幂函数方程为基础的森林密度管理曲线,求出了刚竹竹秆平均胸径((?))与密度(P)之间的最大密度曲线,并把35%密度线作为进行连年间伐情况下的平均密度管理曲线(图1)。但是,刚竹林是由新竹和母竹共同组成的林分,与一个林分只能由同令个体组成这一3/2幂函数方程的前提条件不符。内村(1973)指出,新竹的个体密度(Ni)与母竹密度(前几年立竹密度 P_(i-1))及新竹平均胸径((?)_(ni))之间存在(图2)和(图3)的关系。它们可用(1)式和(2)式来表示, Uchimura (1973) calculated the maximum density curve of average bamboo diameter (?) And density (P) of bamboo culm based on the forest density management curve based on the 3/2 power function equation and found that 35% The density line is used as the average density management curve for successive years of thinning (Figure 1). However, just bamboo is a forest composed of Hsinchu and mother bamboo, which is inconsistent with the prerequisite of a 3/2 power function equation that a forest can only be composed of individuals. Neimura (1973) pointed out that there exists between the individual density (Ni) of Hsinchu and the density of mother bamboo (the bamboo density P_ (i-1) in previous years) and the average breast diameter (Hm ) And (Figure 3). They can be (1) and (2) to represent,
