| 摘 要： | 通过对大兴安岭原始兴安落叶松林分直径结构进行研究,分析兴安落叶松林和白桦林木株数和蓄积按径阶分布的特点。分析结果表明:兴安落叶松林分总体上表现出较明显的原始天然异龄林特点,直径分布结构符合原始天然林的自然生长规律,总体上呈波动的倒"J"字型曲线,这可能是由于该林分中林木的生物学特性和生境共同作用的结果。该研究为科学经营提供理论依据。

| Abstract: | By studying the stand diameter structure of the original Larix gmelinii forest in Daxinganling,the distribution features of the tree number and stand volume according to diameter class of the Larix gmelinii and Birch were analysed.The results showed that the stand of Larix gmelinii forest presented obviously features of the original uneven - aged forest,the structure of diameter distribution was consistent with its original natural forests with inverse J type generally.It was possible due to the impact of n... |
