摘　　要：根据城市园林绿化植物生态作用的有关原理,选取典型的城市园林绿地进行小气候实测分析。试验选择元大都城垣遗址公园4个不同结构类型的园林绿地为研究对象,在冬季进行了连续3 d的试验。研究结果如下:由常绿针叶林构成的纯林、混交林型的乔-草型绿地上的湿度较高,温度较低,具有降温增湿效应;草坪型绿地和由落叶乔木构成的乔-草型绿地上的温度较高,湿度较低。经研究得出了不同结构类型园林绿地温度、湿度的分布规律及差异,并对城市绿化提出了建议。Based on the situation of urban heat island and the theory of urban green land plant ecology effect,typical urban greenland was selected and its microclimate was measured. The ecological benefits on urban green space of Yuan Da- Du Park in Beijing were studied in this paper. Four kinds of green space were studied in this experiment. The experiment was lasted for three days sequentially in winter. In this study, air temperature and relative humidity were continuously measured on these green spaces. The results were as follows： The temperature was lower and the relative humidity was higher in Pinus tabulaeformis woodland and mixed woodland. However, the temperature was higher and the relative humidity was lower in the lawn and Robinia pseudoacacia woodland. The temperature and relative humidity distribution were obtained in this research. At last,some advices for plant landscape building are put farward.
