摘要
应用AHP法对31个苜蓿Medicago sativa品种品质性状进行综合评价,构造递阶层次结构和两两比较判断矩阵,通过层次单排序、层次总排序和一致性检验,求得准则层2个元素(饲用价值和生产价值)的排序权值各占0.5,因素层5个元素(营养成分、适口性、消化率、产草量和再生速度)的排序权值分别为0.319、0.129、0.052、0.334、0.169和11个品质性状的排序全向量。通过综合评分,求得31个苜蓿品种经济价值的综合评价序位,前5位为北疆苜蓿、牧歌401、爱菲尼特、全能和巨人201。最后通过层次分析法(AHP)与灰色关联度法对31个苜蓿品种经济价值的综合评价相比较,结果证明所得结果均具有可靠性,而AHP法更为合理准确。
This study applied Analytic Hierarchy Process to comprehensive assessment of the economic characteristics of 31 alfalfa varieties. The results were as follows： weighting values of feeding value and productive value were 0. 5 each, those of nutrient, palatability, DOM digestibility, hay yield and rate of regeneration were 0. 319, 0. 129, O. 052, 0. 334, 0. 169. By comprehensive assessment, Beijing, Amerigraze401, Affinity, Total and Ameristand201 had the highest score of 31 alfalfa varieties. Finally, we compared the results of comprehensive assessment respectively by Analytic Hierarchy Process and by grey relation degree. It showed that both had high reliability, and Analytic Hierarchy Process was more reasonable.
