| 摘 要： | 依据群落学的调查资料,利用TWINSPAN分类法对徐州市近50年生的34个侧柏人工林群落进行了分类;并运用频度、重要值和径级分析法,分析群落的树种组成和径级结构,探讨人工林的自然化发展趋势和近自然化改造途径。结果表明:现有侧柏人工林内已不同程度地侵入了一些阔叶树种,表现出了自然化的发展趋势;不同的立地条件下侧柏人工林的自然化发展速度不同;现有人工林内各树种的径级分布均有间断,树种自身的天然更新困难。侧柏人工林的近自然化改造应重视对林冠下侧柏及其它阔叶树种的培育,按照"侧柏人工林→针阔混交林→阔叶林"的模式,因地制宜地分阶段进行。

| Abstract: | 34 plots communities for ages of no more than 50 years were classified by using TWINSPAN method based on community survey data.Then,the woody composition structure and diameter classes structure for these communities were analyzed and the plantations naturalization tendency and reconstructing approach close to nature were discussed by using the frequency and important value,and diameter classes analysis method The results showed that three plantations were still dominated by the Platycladus orientalis,howev... |
