| 摘 要： | 通过"样方标准地调查法"研究了依兰国营林场不同林分结构内柞树的生长状况,通过方差分析和多重比较方法得到柞树在针阔混交林、阔叶混交林和柞树纯林中的生长状况排序。结果表明:针阔混交林内柞树的胸径年均生长量、树高年均生长量和材积年均生长量3项指标在18~42 a之间均明显高于阔叶混交林内柞树和柞树纯林,优势明显。所以,无论从生态角度还是用材角度,培育混交异龄复层林结构对森林的永续经营和利用具有重要的作用。

| Abstract: | The growth conditions of oak trees in Yilan State Forest Farm were surveyed by using the sample plot method.The growth conditions of oak trees in mixed broadleaf-coniferous forest,mixed deciduous broadleaved forest and pure forest were made clear through analysis of variance and multiple comparison.The results indicated that oak tree's DBH annual growth,annual tree height growth and annual volume growth in mixed broadleaf-coniferous forest are higher than mixed deciduous broadleaved forests and pure forest ... |
