基于层次分析法的4种山茶科植物观赏价值评价

Evaluation of Ornamental Value in Four Camellia Species Based on AHP Method

应用层次分析法,对猪血木(Euryodendron excelsum)、杜鹃红山茶(Camellia changii)、越南抱茎茶(C.amplexicaulis)、石笔木(Tutcheria championi)4种山茶科植物的树形、花、叶和果进行观赏价值综合评价,结果显示:在树形、花、叶、果4个影响因子中,花因子最能影响人对植物的评判,其次是树形、叶,最后是果;4种植物中,最佳观树形植物是猪血木,最佳观叶、观花植物是杜鹃红山茶,最佳观果植物是石笔木。4种植物的综合观赏价值从高到低依次为杜鹃红山茶>越南抱茎茶>猪血木>石笔木。

The ornamental value of four Camellia species, namely, Euryodendron exeelsum, Camellia ehangii, Camellia amplexicaulis and Tutcheria ehampioni, were evaluated by Analytic Hierarchy Process method. The results showed as follows： among the four influential factors of tree shape, flower, leaf and fruit, the factor that could mostly influence on people＇s evaluation of different plants was flower factor, following with the tree shape, leaf and fruit. By comparing of 4 species, the best tree shape ornamental plant was E. excelsum, the best leaf and flower ornamental plant was C. changii, and the best fruit ornamental plant was T. ehampioni. The sequence of ornamental value of the four species from high to low was C.. ehangii 〉 C. amplexieaulis 〉 E. exeeIsum 〉 T. championi.
