幼龄柞矮林林分生产力低,面积大,树种组成相对单一。其株数按径阶分布呈非正态分布,2cm、4cm径阶占大多数;公顷株数2000株以上出现枯损;以榛子柞林这一类型林分生产力最高,胡枝子林型生产力最低。
Young oak piedmont forest with low productivity, large area, the species composition is relatively simple. The number of trees distributed in a non-normal distribution according to the radial order, 2cm, 4cm diameter of the majority; hectares more than 2000 plants showed a loss; with hazelnut oak forest the highest productivity, Lespedeza branch of the lowest productivity.
