通过对收集的我国沙松自然分布区10个种源球果高、球果径、球果高径比等表型特征的研究，探讨了沙松不同种源球果表型性状的地理变异规律。结果表明：对于球果表型特征而言，不同种源的球果表型特征差异显著，其中，辽宁地区的种源最好，东京城和林口的次之，吉林地区和海林的最差；沙松不同种源球果的表型性状指标表现出自分布区西南向东北的规律性变异趋势；随着海拔的增高，球果高、径和质量呈现出明显的下降趋势。

Phenotypic traits of height ,diameter ,height-to-diameter ratio of cones for 10 collected provenances of Abies holophylla in natural distribution area in China were studied .Geographic variation of phenotypic traits of cones with different provenances for cones of Abies holophylla were explored .Result shows that :for the purposes of the phenotypic traits of cones ,phenotypic traits of cones with different provenances have significant differences ;a-mong them ,the optimal provenances are in Liaoning Province ;Dongjing City and Linko City followed ;Jilin Region&Halin City are the worst ;phenotypic traits of cones with different provenances of Abies holophylla show regularity variation trend from the southwest of distribution area to the northeast .The height ,diameter & weight of cones de-crease w ith the increase of the altitude .
