基于AHP法的南亚热带新优乡土行道树种综合评价及推荐

Comprehensive Evaluation and Recommendation of Novel and Excellent Native Street Trees in Southern Subtropics of China Based on AHP

摘要:

采用层次分析法（AHP）构建了行道树种综合评价模型，设定了5 个准则层和16 个指标层，对46 种乡土树种开展综合评价，为南亚热带地区行道树种的筛选评价提供参考模型。结果表明：黄樟Camphora parthenoxylon、蝴蝶果Cleidiocarpon cavaleriei、千果榄仁Terminaliamyriocarpa等 7 种树种综合表现优异； 大叶桂樱Prunus zippeliana、华润楠Machiluschinensis、苦梓含笑Michelia balansae等21 种树种表现良好，均可广泛选作广东中南部、广西中南部、云南中部等南亚热带城市的行道树。同时，筛选12 种新优乡土树种进行推介，为南亚热带城市行道树种选择提供参考。

Abstract:

Based on the Analytic Hierarchy Process (AHP), this article proposes a comprehensive evaluation model to screen and evaluate street tree species in the Southern Subtropics of China. The model incorporates 5 criterion layers and 16 indicator levels. 46 native tree species from the Southern Subtropics in China are evaluated in detail using this model. The results indicate that 7 species, such as Camphora parthenoxylon, Cleidiocarpon cavaleriei and Terminalia myriocarpa exhibit excellent performance; 21 species, such as Prunus zippeliana, Machilus chinensis, Michelia balansae show very good performance. All of these native species are recommended for wide use as urban street trees in cities in the south-central subtropical regions of Guangdong and Guangxi, as well as in the central subtropical regions of Yunnan. Concurrently, twelve new superior native tree species have been selected for promotion, providing a reference for selecting street tree species in South subtropics cities.
