| 摘 要： | 对伊春林区天然阔叶混交林中黄菠萝、胡桃楸和水曲柳3个树种在桃山、南岔、翠峦、上甘岭和新青5个自然分布区内的群落结构的差异显著性进行比较分析,并对其相互关系进行了研究。结果表明:桃山林业局3个树种在树高、胸径因子上占有明显优势;树高与胸径的相关系数是0.875,呈显著正相关;树高与胸径回归方程的拟合优度最高达0.825,回归方程的最佳拟合函数是三次函数。

| Abstract: | The difference significance of population structures of Phellodendron amurense,Juglans mandshurica and Fraxinus mandshurica in five natural distributions and researches correlation between tree height and DBH were studied.The results showed that tree height and DBH of three tree species in Taoshan forestry bureau was better than others.The correlation coefficient of tree height and DBH which was significant positive correlation was 0.875.Cubic was the best fitting function of tree height and DBH whose goodn... |
