摘　　要：园林绿地在调节环境温湿度方面发挥着重要作用。选择不同植物种类组成的校园绿地作为研究对象,结合其对人体舒适度的影响,将绿地对校园小气候的改善作用进行定量化研究。2015年1月14-23日,每天8:00-18:00,每2h1次分别对西北农林科技大学南校区校园内具有代表性的6处样地的温度、相对湿度和风速进行同步测定。结果表明:校园绿地相对于无绿化地面均表现出增湿效应,在温度调节方面表现为减小温度的变化幅度,并对人体舒适度均有一定的改善。将晴朗天气14:00的温湿度进行多重比较(Bonferroni’s多重分析,p<0.05)分析发现,冬季常绿植物构成的校园绿地对校园小气候的调节和人体舒适度的改善具有较为明显的作用。Green spaces play important roles in regulating the environment temperature and humidity. Tak- ing the green spaces that were composed of different plant species in the south campus of Northwest A＆F University as research objects,combining with degrees of human comfort,a quantitative study was conduc- ted on the improvement of campus microclimate by the green spaces. Six typical sites were selected, in which the temperature, relative humidity and wind speed synchronously measured once every two hours from 8：00 to 18：00 every day on January 14 to 23,2015. The results showed that the campus green spaces could increase atmospheric humidity, reduce the scope of temperature variation, and improve human com- fort. Multiple comparison analysis of the data of temperature and humidity recorded at the time of 14：00 in sunny days showed that evergreen species in the campus significantly adjusted the miroclimate and im- proved human comfort.
