广州市主要园林树种抗风性评价

我国东南沿海地区每年因台风导致的树木毁坏及次生灾害损失严重。通过分析广州市近年来26种主要园林植物风害受损和形态学指标数据,利用层次分析法、综合评价法和模糊隶属函数法分别对风害受损指标和形态学指标进行综合评分,再根据评分结果进行聚类分析。结果表明,按受损指标统计和形态学指标评估可分别将26种园林植物分成3个类群,14种植物类别完全一致,12种植物类别相近,没有出现相互矛盾。其中,抗风性较好的树种有樟Cinnamomum camphora、海南蒲桃Syzygium hainanense、阴香Cinnamomum burmannii、木棉Bombax ceiba、红花羊蹄甲Bauhinia×blakeana、鸡冠刺桐Erythrina cristagalli、高山榕Ficus altissima和糖胶树Alstonia scholaris。

Evaluation on Wind-resistance of Main Landscape Plants in Guangzhou

The wind disaster activity in our country is frequent and the influence is great.The tree damage and secondary disaster loss caused by typhoon are serious every year.By studying the wind damage and morphological index of 26 main landscape plants in Guangzhou,the comprehensive score of wind damage index and morphological index was carried out by using Analytic Hierarchy Process (AHP),comprehensive evaluation method and fuzzy membership function method,and then cluster analysis was carried out according to the score results.The results showed that 26 plants could be divided into 3 groups,14 species were identical,12 species were similar,and there was no contradiction.Among the 26 plants,Cinnamomum camphora,Syzygium hainanense,Cinnamomum burmannii,Bombax ceiba,Bauhinia × blakeana,Erythrina crista-galli,Ficus altissima and Alstonia scholaris are better wind-resistant plants.
