基于层次分析法评价12种虾脊兰属植物的观赏性和生长适应性

Evaluation of ornamental and adaptability of 12 Calanthe species based on analytic hierarchy process

采用层次分析法对福建农林大学森林兰苑引种的12种兰科虾脊兰属植物的观赏性、生长适应性、潜在价值进行分析与评价.结果表明:(1)在观赏性方面,大黄花虾脊兰、三褶虾脊兰、银带虾脊兰评价得分分别为24.679 2、24.091 6、22.328 8分.(2)在生长适应性方面,三褶虾脊兰、银带虾脊兰、大黄花虾脊兰评价得分分别为12.936 0、12.936 0、12.289 2分,生长适应性最强.(3)在潜在利用价值方面,Ⅰ级(>33.885 0分)、Ⅱ级(32.330 0～33.880 0分)、Ⅲ级(<32.300 0分)植物各有4种.综合分析认为,三褶虾脊兰、大黄花虾脊兰、银带虾脊兰适合在福州地区的园林景观中推广应用.

12 species of Calanthe introduced to Orchid Garden of Fujian Agriculture and Forestry University were analyzed and eval-uated by analytic hierarchy process based on ornamental value, adaptability and potential value. The results showed that 3 specieswith the highest ornamental values were C.sieboldii, C.triplicata, C.lechangensis in a descending order while species with the highestadaptability were C. triplicata, C. sieboldii, C. argenteo-striata in a descending order. Plants of Grade Ⅰ （ 〉 33. 885 0 points）,Grade Ⅱ （32.330 0-33.880 0 points） and Grade Ⅲ （〈32.300 0 points） consisted of 4 species in terms of adaptability. To summa-rize, C.triplicata, C.striata and C.argenteo-striata are very likely to be used as landscape plants in Fuzhou .
