摘　　要：采用双重分类法,将山西省的沙棘分为7大自然类型,即黄果型、红果型、圆果型、扁果型、大果型、小果型、一般型。又根据产果量、果密度、果柄长、刺长4个重要经济指标,用Q聚类法划分为28个亚类。运用形态特征和经济性状相结合的方法划分类型,既易于野外识别,又可表明其经济利用价值和品种改良的前景,也能反映进化上的特点与遗传方面的差异。Hippophae rhamnoides in Shanxi Province was classified as 7 natural types by two-fold-classification, such as yellow fruit type, red fruit type, round fruit type, flat fruit type, large fruit type, small fruit type and general type. And 28 subclasses were classified by Q clustering method according to the 4 important economic indexes of fruit yield, fruit density, stalk length and thorn length. The classification method combining morphological characters and economic indexes could not only show its economic value and prospect for variety improvement, but also reflect the evolutionary characteristics and genetic differences.
