运用层次-关联分析法综合评价加拿大引种草本花卉

The Comprehensive Evaluation of the Ornamental Flower Plants Introduced from Canada by the Application of Hierarchy-relation Analysis

以花色、花期、花美感、植株抗旱性、耐寒性等为评价指标,利用灰色关联理论与AHP(层次分析法)结合的层次-关联评判分析法,对引种到陕西关中地区的18种草本花卉进行了综合评判。结果表明:三月花葵(Lavatera trimestris)、冰岛罂粟(Papaver nudicaule)、苏丹凤仙(Impatiens sultanii)和风铃草(Campanula medium)的生长势较差,综合评价值也较低;牛舌草(Anchusa azurea)、肿柄菊(Tithoniao tundifilia)、毛地黄(Digitalis purpurea)和一串蓝(Salvia farinacea)等8种花卉能适应关中地区的环境,并且综合评价值较高,适宜在陕西等地区进一步推广应用。
