摘  要:
根据36块标准地250株伐倒水的资料,通过建立锐齿栎各器官生物量、材积和叶面积的估计方程,研究了秦岭锐齿栎林的生物量和生产力。结果表明:秦岭南坡的锐齿栎林生长普遍优于北坡,在南坡以中段分布区生长最好,在北坡以西段分布区生产力最高。在同一分布区内,锐齿栎的生物量和生产力随林分类型、叶面积、林龄、密度及海拔等因素而变化。在秦岭林区锐齿际林的平均蓄积量为181.2m3/hm2;平均现存量为208.4t/hm2;叶面积指数5.631;平均生产量17.97t/hm2。秦岭林区的锐齿栎林具有很高的生产力。

摘  要:
Based on the date from 36 sample plots and 250 sample stems,biomass and preductivi-ty of the sharptooth oak forests in thc Qinling Mountains were analysed by the way of simulating regressions of biomass volume qnd leaf-area of each organs of the sharptooth oak. The results in-dicated that growth of shiarptooth oak forest on south-facing slope was better than that of the north-facing slope. On south-facing shope, the stand at the middle range was the best,while that at wcst range on north-facing slope had the best growth,Bomass and preductivity varied with stand - type, leaf- area ,stand age,density and elevation in the same natural range. Average stocked volume, average standing crop, leaf - area indics, average production of sharptooth oakforests in the Qinling Mountains werG 181.2m3/hm2, 208, 4t/hm3, and 5. 631 and 17. 97t/hm3 respectively. Sharptooth oak foresis in the Qinling Mountains had very large productivity.
