| 摘 要： | 本文应用平均相对形率系列的方法,对油松和巴山松的干形进行了分折比较。结果表明:油松与巴山松的干形的相对形率系列有明显的差别,巴山松根部及尖削度相对于油松,其余部分相对大于油松。因此,两者应分别建立相对形率系列作为各自的干形指标。

| Abstract: | Stem forms of p. tabuldeformis Carr. and p. henryi Mast, were Compared using the method of average relative form-rate series. The result shows that relative form-rate series of two species are different, stem taper in base part of p,henryi is relativdy little than that of p.tabulue formis. So relative form-rate senes of the two species should be established separately. |

| Keywords: | Finus tabulaefomis Carr. pinus henryi mast relative stem form form-rate comparison |
