摘　　要：为了能够让引种工作者在引种材料较多时定量地比较宿根花卉观赏性状及景观应用价值,从形质性状、开花性状、生长性状等方面确定了鸢尾宿根花卉评价的3级指标,采用层次分析法(AHP法)测算指标权重,并采用熵技术对权系数进行修正,从而得到鸢尾宿根花卉的综合评价模型。利用该模型对沈阳市植物园近几年引种栽培的鸢尾宿根花卉的50个种和品种进行了综合评价并分级,其中Ⅰ级的有10种、Ⅱ级的有18种、Ⅲ级的有15种、Ⅳ级的有7种。研究为鸢尾宿根花卉在园林绿化中的应用提供了一定的理论参考。In order to quantitatively contrast the ornamental characters of perennial flowers and landscape application value, when there are more introduction materials, an evaluation index system for Iris perennial flowers was established in terms of natural characters, blossoming characters and growing characters. The importance weights were calculated by the analytic hierarchy process （AHP）, and the weight coefficients were modified by the entropy technology, so a synthetic evaluation model about Iris perennial flowers was obtained. According to this model, about 50 species Iris in Shenyang Botany Garden were evaluated and classified. A total of 10 species were selected as the first grade, of which 18 species as the second grade, of which 15 species as the third grade, and 7 species as the forth grade. This study would provide a good theoretical guidance and an important reference value for the application of iris perennial flowers in the landscaping.
