摘要
选取南宁市3条主干道路的5种绿化树种大王椰子、扁桃、大花紫薇、木棉和人面子为研究对象,在1d内测定其树下空气温度、空气湿度及大气辐射日变化。结果表明:对比于裸地的空白对照来讲,大王椰子、扁桃、大花紫薇、木棉和人面子树下的空气温度和大气辐射都有明显的降低,但树下空气湿度并没有明显差别。5种树下空气温度和大气辐射的日变化曲线呈"单峰"型,空气湿度日变化曲线呈"U"型。在此研究结论基础上提出了南宁市绿化树种的选择建议。
Diurnal variations of air temperature,air humidity and atmospheric radiation under Roystonea regia,Mangifera persiciforma,Lagerstroemia speciosa,Bombax ceiba and Dracontomelon duperreranum on street trees in Nanning were studied in May.Compared to those blank control on the bare,air temperature and atmospheric radiation under Roystonea regia and Mangifera persiciforma,Lagerstroemia speciosa,Bombax ceiba and Dracontomelon duperreranum was decreased remarkably in the four seasons,but air humidity under the trees was not remarkably different.The diurnal variation curve of air temperature and atmospheric radiation on five street trees shows single peak.Some proposals were put forward on study.
