| 摘 要： | 通过调查牡丹江地区的26块蒙古栎林标准地橡实产量,研究立地因子和林分因子对蒙古栎林橡实产量影响的结果表明,立地因子和林分因子对蒙古栎橡实产量影响不同,按影响大小排序为:密度>胸径>坡度>海拔>树高>树龄>土壤厚度>坡位>坡向>郁闭度,处于低海拔、阳坡半阳坡的低密度中龄林橡实产量较高。

| Abstract: | Through investigating the acorn yield of 26 Quercus mongolica forests in Mudanjiang area, the results of studying the effects of site factors and stand factors on acorn yields showed that the site factors and stand factors have different effects on acorn yields of Quercus mongolica forests. The order of impact size was: density>DBH>slope>altitude>height>age>soil thickness>slope position>aspect>canopy density, acorns of low-density middle-aged forests at low altitude, sunny slope, half sunny slope The yield is higher. |
