摘要
本文系统地研究了区域和立地条件对麻栎林生长的影响,提出了麻栎生长的最佳适生区。麻栎林的生产力随海拔和纬度的增加呈递减趋势,麻栎林林分生物生产力具有经向、纬向和垂直向的变化规律。麻栎生长在阳坡20°以下、山中腹小于30°的沙壤土最好。
The influence of site region and condition on Quercus acutissima rowth was studied in this paper systematically. The result shows that optimum growing region is at sunny slope below 20 degree or mid-slope below 30 degree and sandy soil is the best.It also indicates that stand productivity tends to a gradul reduction and has a regularity of varying with longitude,latitude and altitude.
