校园绿化小气候效应及其对人体舒适度的影响——以山西农业大学校园为例

Microclimate Effects of Campus Greening and Impact on Human Comfort Index——Case of Shanxi Agricultural University

为了明确校园绿化环境对校园小气候的影响,对校内3个绿化地和1个非绿化地进行了空气温度和湿度的对比观测,并利用校外自动气象站的温湿度资料和校内各测点温湿度进行了比较。研究表明:绿化可以使校内气温下降,空气湿度增加,从而增加人体的舒适感。校内绿地和非绿地空气温湿度与校外气象站的温湿度观测值极显著相关,并可以建立回归关系显著和决定系数(R2)较高的线性回归方程。校园绿化可以改善校内小气候环境,校内的小气候环境与校外大的气候环境密切相关。

In order to clarify the effect of campus greening on campus microclimate,the air temperature and humidity of 3 campus green space and a non-green space were observed in this study.We also compared the air temperature and humidity between in automatic weather station and in campus.The results showed that campus greening descend the air temperature and increased the air humidity,thus increasing the body＇s comfortable feeling.The air temperature and humidity of campus were significantly associated with the temperature and humidity in automatic weather station.Linear regression equation with significantly regress connection and higher determination coefficient（R square）were established.Campus greening can improve microclimate condition of campus.The microclimate of campus was closely associated with the climate environment outer of the campus.
