摘　　要：应用灰色系统理论——灰色关联度分析法,对天祝高寒草甸区种植的36个燕麦品种的营养成分含量进行了综合描述和量化评估,通过对各品种加权关联度的比较,较为全面、客观地评价其品种的优劣和应用价值。利用灰色关联度分析法对不同燕麦品种的综合评价效果得知,青永久316在供试品种中表现最好,营养价值最高,其次是青永久87-6-21、小红燕麦、青永久208、甜燕麦和4617。此6种燕麦品种与"参考品种"的加权关联度都大于0.60,可作为高寒牧区种植燕麦主要推广品种。青永久97等11个燕麦品种营养价值较高,表现较好,可适当推广种植。The nutritive values of 36 oat varieties planted in Tianzhu alpine meadow were evaluated comprehensively using the grey system theory—grey correlation degree meathod.The results showed that Avena sativa L.cv.Qingyongjiu No.316 had the best performance and highest nutritional value among tested varieties,followed by A.sativa L.cv.Qingyongjiu No.87-6-21,A.sativa L.cv.Xiaohong,A.sativa L.cv.Qingyongjiu No.208,A.sativa L.cv.Tianyanmai and A.sativa L.cv.No.4617.The weighted correlations between these six varieties and referenced varieties were all more than 0.60,this results indicated that these six varieties could be used as the main planting varieties of forage oats in agricultural and pastoral areas.11 species of oats,inclouding A.sativa L.cv.Qingyongjiu No.97,had higher nutritional value and better performance,and could be promoted propely.
