龙岩市城区乔木多样性调查与应用

Investigation of Arbor Diversity and Application in Longyan City

以龙岩市城区十五个住宅小区和五个城市公园中的乔木为研究对象,通过对乔木物种多样性、生长情况及景观应用进行调查,进一步研究城市景观乔木的生态特性。结果表明:城区主要乔木树种共有46科79属98种,其中常绿乔木30科53属65种,落叶乔木19科29属33种,被子植物41科68属84种,裸子植物7科11属14种,频度前十位的乔木为:高山榕(Ficus altissima)、樟树(Cinnamomum camphora (L.) Presl)、红花羊蹄甲(Bauhinia blakeana Dunn)、榕树(Ficus microcarpa Linn. F.)、鸡蛋花(Plumeria rubra L. cv. Acutifolia)、木犀(Osmanthus fragrans)、垂叶榕(Ficus benjamina)、盆架木(Alstonia scholaris (L.) R. Browm)、美丽异木棉(Ceiba speciosa St.Hih.)、菩提树(Ficus religiosa L.)。探讨乔木对城市环境的适应性及景观配置合理性,并为龙岩市城区景观乔木的选择、景观应用及养护提供建议。

The ecological characteristics of urban landscape arbor were further studied by taking the arbor in fifteen residential areas and five urban parks in Longyan city as the studying objects and by the investigation of arbor species diversity, growth and landscape application. The results show that： there are 45 families, 78 genera and 96 species of main arbor species, including 64 species in 52 genera and 29 families of evergreen trees, 32 species in 28 genera and 18 families of deciduous trees, 82 species in 67 genera and 40 families of angiosperms, 14 species in 11 genera and 7 families of gymnosperms. The top 10 degree of presence of 10 arbors were as follows： Ficus altissima, Cinnamomum camphora （L.） Presl, Bauhinia blakeana Dunn, Ficus microcarpa Linn. F. , Plumeria rubra L. cv. Acutifolia, Osmanthus fiagrans , Ficus benjamina , Alstonia scholaris （L.） R. Browm, Ceiba speciosa St. I-Iih., Ficus religiosa L. Based on the results, the adaptabihty of trees to urban environment and the rationality of landscape configuration were discussed, which may provide suggestions for the selection, landscape application and maintenance of trees in Longyan city.
