The CVD is an important index to indicate tree diameterdifferentiating.On basis of dynamic change and tendency of CVDamong trees in stand,three models of square CVD are proposed.i.e.,basic model,stand factor model,and thinning effects model.All threemodels are of mechanism,asymptotic characteristic,and invariance forprojection length.Futhermore,there are compatiability and extremevalues in thinning effects model for thinned and unthinned stands.
直径变动系数是描述林木直径分化的重要指标,根据林木直径变动系数的动态变化和趋势,本文提出了直径变动系数平方动态变化的三个模型:基本模型,与林分因子相关的模型,考虑间伐效应的模型,上述三个模型均具有一定的机理性、渐近性和步长不变性,特别是考虑间伐效应的模型为间伐林分和未间伐林分的相容性模型,它还具有相容性和极值性。
