通过对应用厚朴与日本落叶松混交模式在高寒山区的不同地类、不同坡位和坡向造林后三年生幼树生长情况调查分析。结果表明:造林地类、坡位和坡向等因子对造林成活率、幼树的高生长和地径粗生长影响显著。在造林地类中,以坡耕地造林的幼树生长明显优于荒山荒地的;在荒山造林中,坡位和坡向对幼树的生长产生显著影响,在阴坡的山下部环境中厚朴生长最好,阳坡的中、下部环境中日本落叶松生长效果最好,其它坡向坡位次之。
Through the application of Magnolia officinalis and Japanese larch mixed mode in the alpine area of different land types, different slope positions and slope afforestation after three years of young tree growth survey. The results showed that factors such as afforestation landform, slope position and aspect had significant effects on afforestation survival rate, sapling height growth and diameter diameter coarse growth. In the afforestation land, the growth of young trees on sloping farmland was significantly better than that of barren hills and wastelands. In the afforestation of barren hills, the slope position and aspect had a significant effect on the growth of saplings. In the shady hillside environment, The best growth, sunny slope in the lower part of the Japanese larch growth best, followed by other slope to the next.
