南亚热带主要城市行道树树种调查研究

An Investigation on Species of Roadside Tree in Southern Subtropical Main Cities of China

通过对南亚热带13个主要城市的1667条主要道路行道树生长状况的调查,结果表明,共有101种(含种以下单位)乔木用作行道树。它们分别隶属于32科68属,其中乡土树种占53.47%,常绿乔木占75.25%,其中87.13%的乔木生长良好。研究认为:海南蒲桃(Syzgium cumini)、非洲桃花心木(Khaya senegalensis)、木棉(Bombax ceiba)、芒果(Mangifera indica)、扁桃(Mangifera persiciformis)、海南红豆(Ormosia pinnata)、秋枫(Bischofia javanica)、细叶榕(Ficus microcarpa)、麻楝(Chukrasia tabularis)、樟树(Cinnamomum camphora)、阴香(Cinnamomum burmanii)、垂叶榕(Ficus bengjamina)、高山榕(Ficus altissima)、尖叶杜英(Elaeocarpus apiculatus)、人面子(Dracontomelon duperreanum)、红花羊蹄甲(Bauhinia blakeana)、凤凰木(Delonix regia)、白兰花(Michelia alba)、大花紫薇(Lagerstroemia speciosa)、糖胶树(Alstonia scholaris)、紫檀(Pterocar pusindicus)、蝴蝶果(Cleidiocarpon cavaleriei)、石栗(Aleurites moluccana)、蒲桃(Syzgium jambos)等24种乔木适宜作为南亚热带城市行道树的骨干树种;大叶榕(Ficusvirens var.sublanceolata)、黄槐(Cassia suffurtiosa)等31种乔木可作为行道树一般树种。

An investigation on species of roadside tree in southern subtropical cities of China was conducted in 2003. The results showed that there were 101 species and varieties of the plants used as roadside trees, belonging to 32 families and 68 genera, and 53.47% and 75.25% species or varieties of them were native and evergreen trees respectively. Syzgium cumini, Kfiaya senegalensis, Bombax ceiba, Mangifera indica, Mangifera persiciformis, Ormosia pinnata, Bischofia javanica, Ficus microcarpa, Chukrasia tabularis, Cinnamomum camphora, Cinnamomum burmanii, Ficus bengjamina, Ficus altissima, Elaeocarpus apiculatus, Dracontomelon duperreanum, Bauhinia blakeana, Delonix regia, Michelia alba, Lagerstroemia speciosa, Alstonla scholaris, Pterocarpus indicus, Cleidiocarpon cavaleriei, Aleurites moluccana, Syzgium jambos were suitably used as main species of roadside trees in those cities. The other 31 species of tree, such as Ficus virens vat. sublanceolata and Cassia suffurtiosa, were suitably used as general species.
