摘要
在文献资料和实地调查的基础上,综合考虑植物观叶价值,树形、干形、观花、观果等其他观赏价值和生态适应性因素,确定12个评价因子,建立槭树属植物资源层次分析(AHP)评价模型,对已筛选出的17种槭树属植物资源的园林应用综合价值进行评价。结果表明:12个评价指标中,指标P_1(叶色)权重值最大,占34.70%;其次是P3(彩叶期),占21.90%;再次是P_2(叶形),占9.20%;然后是P_5(观花),占7.60%,其余指标的权重值相对较低。根据综合评价结果,将17种槭树属植物划分为3个等级:Ⅰ级包括元宝槭等10种槭树属植物,园林应用价值最高;Ⅱ级包括茶条槭等5种槭树属植物,其园林应用价值较高;Ⅲ级包括2种槭树属植物,其园林应用价值最低。
Based on the literature and field survey, this paper used the analytic hierarchy process （AHP） method to evaluate the landscape application value of 17 Acer species from the aspects of plant foliage, other ornamental value and ecological adaptability. The results showed that among the 12 evaluation indicators, indicator P1 （Leaf color） had the largest weighted value, accounting for 34.70%, followed by P3 （Coleus period）, P2 （Leaf shape） and P5 （Flower）, accounting for 21.90%, 9.20% and 7.60%, respectively, while the rest of the indicators had relatively low weighted values. According to the comprehensive evaluation result, 17 Acer species could be classified into 3 grades. Ten Acer species were selected as the first grade, indicating the highest landscape applica- tion value; five in the second grade, belonging to the higher landscape application value and two in the third grade, having the lowest application value.
