紫椴用材林主伐年龄和轮伐期的确定

Ascertainment of Principal Felling Age and Rotation of Tilia amurensis Timber-forest

在收集大量数据的基础上 ,以大径材的工艺标准为目标 ,根据树种分布、生态区特点、生长节律、相关模型 ,系统研究了主伐年龄和轮伐期的确定问题 ,比已有的规程有了新的突破 ,为定向培育提供了科学依据。

Basing on plenty of data, aiming at large timber technical criterion, considering distribution, environment trait, growth rhythm and correlation model, the authors studied the ascertainment of the principal felling age and rotation of Tilia amurensis timber-forest. The results showed that the regulation put forward in this paper made a new breakthrough by contrasting with old regulations, and it could provide scientific foundation for directional breeding forest.
