采用层次分析法对我国南部5个省区的22株猴面包树观赏性状进行综合评价,结果表明:(1)综合评价体系准则层中以花果形态美感(B4)的权重值最大,指标层中开花指数(C41)的总权重值最高;(2)评价结果显示:海南地区的猴面包树观赏性状整体比较高。根据评价结果将22株猴面包树划分为4个等级,其中Ⅰ级的有5株,其综合性状表现突出,观赏价值高。

The ornamental characteristics of 22 plants of Adansonia digitata in 5 provinces in the south of China were evaluated by using the analytic hierarchy process（AHP）. The results showed that the beauty of fruit and flower shape（B4） had the highest weight in the criterion layer of the comprehensive evaluation system, while the flowering index（C41） had the highest total weight in the indicator layer. The evaluation results showed that the ornamental characteristics of A. digitata in Hainan were relatively high.According to the results of the evaluation, 22 plants were divided into 4 grades, of which 5 plants were listed into Grade I and had an outstanding performance in comprehensive characteristics with a high ornamental value.
