摘　　要：基于中国科学院西双版纳热带植物园收集保存的爵床科植物资源,运用层次分析法构建评价体系,对67种具有园林应用潜力的爵床科植物进行观赏价值综合评价。结果表明,在一级指标中,花观赏性所占权重最大,表示花观赏性在爵床科植物观赏价值综合评价中是最重要的方面;在二级指标中,花(序)量、花(序)色鲜艳度和盛花期时长对爵床科植物观赏价值的影响权重均超过10%,对评价结果有较大影响,而花(序)大小、花后观赏性和叶片盖度对爵床科植物观赏价值的影响权重均低于5%,对评价结果影响较小。依据指标权重和评分标准,对67种爵床科植物的观赏价值进行综合评分并划分等级,赤苞花(Megaskepasma erythrochlamys)、宽叶十万错(Asystasia gangetica)、鸟尾花(Crossandra infundibuliformis)、翠芦莉(Ruellia simplex)、翼叶山牵牛(Thunbergia alata)、金苞花(Pachystachys lutea)、黄花老鸦嘴(Thunbergia mysorensis)、白苞爵床(Justicia betonica)、叉花草(Strobilanthes hamiltoniana)、绯红珊瑚花(Pachy stachy scoccinea)、白金羽花(Schaueria calytricha)、山牵牛(Thunbergia grandiflora)等12种植物的观赏价值较高,综合评价等级为Ⅰ级,具有较好的园林应用前景。Based on the present collection and conservation of Acanthaceae plants in Xishuangbanna Tropical Botanical Garden(XTBG),Chinese Academy of Sciences(CAS),we used the analytic hierarchy process(AHP)to construct an evaluation system and comprehensively evaluate the ornamental value of 67 Acanthaceae species with potential for application in gardens.The results showed that among the primary indicators,flower ornamentation properties had the highest weight,indicating that flower ornamentation properties were the most significant ornamental value of the Acanthaceae plants.Some of the secondary indicators,including flower(inflorescence)volume,flower(inflorescence)color vividness,and the length of the flowering period,all had more than 10%influence on the ornamental value and had a higher impact on the evaluation results.While the other secondary indicators,including flower(inflorescence)size,post-flowering ornamentation properties,and leaf coverage,all affected the ornamental value by less than 5%and had a lower impact on the evaluation results.The ornamentation value of the 67 Acanthaceae species was rated and graded according to the weighting and scoring criteria.The evaluation concluded that the ornamental value of 12 Acanthaceae species(Megaskepasma erythrochlamys,Asystasia gangetica,Crossandra infundibuliformis,Ruellia simplex,Thunbergia alata,Pachystachys lutea,Thunbergia mysorensis,Justicia betonica,Strobilanthes hamiltoniana,Pachystachys coccinea,Schaueria calytricha,Thunbergia grandiflora)was high,with a comprehensive evaluation gradeⅠand good prospects for application in gardens.
