摘 要 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。

Abstract 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.

猴面包樹(Adansonia digitata)又叫波巴布树、猢狲木,因硕大的果实形似面包,果肉汁多味甜,是猴子和狒狒十分喜爱的食物而得名[1-2]。它是木棉科猴面包树属的大型落叶乔木,一般情况下树高20 m左右,原产于非洲热带干旱地区。地中海、大西洋、印度洋诸岛以及澳洲北部。猴面包树性喜温热,其自然分布区年平均温度一般为20~30℃,较干旱。由于长期适应进化,猴面包树适应了干燥的气候环境,耐旱能力极强,一般在年降水量300~800 mm的地区生长较好。猴面包树的花大而美,主干基部膨大,造型奇特且易于管理,是优良的园林美化树种之一,可用于草坪点缀,花坛孤植,庭院配植等[3]。在我国海南、云南、福建、广东、广西、台湾等热区有少量引种种植[1]。
随着社会经济的发展以及人们生活水平的提高,人们对城市生态环境的要求也逐步提高,在满足城市绿化美化的同时,还需要满足人们对植物更高观赏价值的追求。众所周知,影响城市园林绿化效果最为关键的要素之一就是植物的观赏价值高低。……
