摘　　要：利用层次分析法(AHP)对长春地区引种栽培的30份山楂属种质资源的观赏价值进行综合评价和等级划分。通过建立目标层(A)、约束层(C)、标准层(P)、最低层(D) 4个层次的综合评价模型,选择树形、叶形、生长势、果色、挂果期、花期等14项评价因子,对供试种质材料进行综合评价,并根据评价结果划分为Ⅰ~V共5个观赏等级,其中属于Ⅰ级的种质资源5份,分别为‘山里红1’、‘黑石’、‘艳阳红’、‘山里红3’和‘山里红4’,综合评分均大于3.479 2。研究结果为提高观赏山楂资源筛选效率及优良资源推广提供了理论依据。The ornamental value of 30 hawthorn(Cratae gus L.)germplasm resources introduced and cultivated in Changchun area was evaluated and graded by analytic hierarchy process(AHP).A comprehensive evaluation model of object level(A),restraint level(C),restraint level(P)and lowest level(D)was established,and 14 evaluation factors including tree shape,leaf shape,growth potential,fruit color,fruiting date and flowering date were selected to comprehensively evaluate the germplasm materials.According to the evaluation results,the germplasm materials were divided into five ornamental grades from I~V.Five germplasm resources belonged to level I,which were‘Shanlihongl',‘Heishi',‘Yanyanghong',‘Shanlihong3'and‘Shanlihong4',with the comprehensive score higher than 3.4792.The results of this study provide a theoretical basis for improving the efficiency of ornamental hawthorn resource screening and promoting excellent resources.
