摘要
通过对影响干旱沙地樟子松造林成活率的５种因素———土厚、风、干旱程度、光照、苗木质量的数量化分析得出，造林成活率的影响因素按大小排序为：光照、干旱程度、风、土厚、苗木质量；造林保存率的影响按大小排序为：风、光照、干旱程度、苗木质量、土厚．并且各因素间相互联系。
Effect of five factors on Pinus sylvestris var.Mongolica afforestation survival rate—soil thickness,wind,drought degree,light,seedling quality.The results showed,afforestation survival rate in effect sequence are arranged as light,drought degree,wind,soil thickness,seedling quality;Afforestation reserving rate in effect sequence is wind,light,drought degree,seedling quality,soil,thickness.All factors were interacted and on each other.
