摘要
本文在样地调查的基础上研究了楠木叶面积的测定方法和叶面积指数的测定及生物量、材积、林分密度与叶面积指数间的关系,得出在现有林分条件下单位面积上的生物量、材积与叶面积指数均成线性回归关系,而叶面积指数与林分密度的倒数成二次回归关系。利用这些关系本文确定出了最佳林分密度的估计值。
This paper, based on sampling surveys, discusses the leaf area and L. A. I. measuring methods, and the relations among L. A.I.and stand biomass. Volume stand densities are also studied. Under the condition of current stand, the biomass and volume on per unit area are related to L. A. I. in linear regression, and the relations between L. A. I. and the reciprocal of stand densities are of quadratic regression. The optimum estimation for stand deusity is here wpon determined.
