采用系统聚类分析、相关分析和模糊综合评价方法对不同行距与播种量组合处理的无芒雀麦种子产量构成因子的数量特征进行了研究.系统聚类分析结果表明：在欧氏距离等于1.5时可将12个播种组合分为2类，第一类为窄行距类，播种组合有A30、B30、C30、B50和C50；第二类为宽行距类，播种组合有A70、B70、C70m、A90、B90、C90和A50.类内种子产量构成因子的数量特征相似，类间差异显著.行距对单位面积生殖枝数、营养枝数、小穗数/花序、秸秆重量、经济系数等的影响较明显，而对穗长、种子数/花序的影响不明显.模糊综合评价结果表明，窄行距类各组合综合效果值（≥0.0927）大于宽行距类（≤0.0852），其中A30和B30组合产量构成因子的综合效果最优.

The cluster analysis and fuzzy comprehensive assessment on 12 sowing schemes of Bromus inermis Leyss were studied by methods of cluster analysis and fuzzy comprehensive assessment.The result showed that 12 sowing schemes were classified two types that were narrow row space type and wide row space type, and there were signifi-cant differences between classifying index of narrow row space type and those of wide row space type. Comprehen-sive effects of sowing schemes in the narrow row space type were much better than those of wide row space type, among them 30 cm row space treatments have best effect of fuzzy comprehensive assessment.
