校园绿色空间布局对微气候的效应研究

本研究以河南农业大学校园为例选取了3个具有不同绿色空间布局形式的测量样点,在人行高度上进行了9 d的风速、风向、温度、湿度、热辐射的数据采集。通过对实测数据分析,秋季静风天天气下,半围合式绿色空间布局的风速、风向变化小于开敞空间和行列式绿色空间布局;相比于其他布局形式,半围合式布局降温1.41℃、增湿4.08%、降低辐射119.25 W·m~(-2),对微气候的改善有明显效果。

Field studies on the effect of campus green space layout form on microclimate

The experiment selected three measuring points with different green space layout forms in Henan Agricultural University,and carried on the 9 × 24 hours of wind speed and direction,temperature,humidity,thermal radiation data acquisition in pedestrian height.By analyzing the measured data,under the condition of autumn static wind,the change of wind speed and direction in semi-closure green space layout was less than in open space layout and determinant architecture green space layout;Compared with other forms of layout,the semi-closure green space layout temperature reduced by 1.41 ℃,increased by 4.08％ in RHhumidify,and reduced by 119.25 W · m-2 in radiation,which has obvious effect on the improvement of the microclimate.
