校园绿地春季小气候及人体舒适度效应分析

为研究不同植物群落空间对人体舒适度的影响,以东北农业大学校园绿地为对象,实地测量小气候数据,采用双因素方差分析法对5种结构类型的植物群落(乔-灌-草、乔-草、灌-草、乔木、草坪)在春季(5月)温度、湿度及温湿指数(人体舒适度)调节能力的差异进行比较.结果表明:春季校园绿地内,不同的植物群落对降温增湿均有一定的调节能力;植物群落比单一草坪具有更好的小气候改善能力,差异呈显著或极显著变化(P<0.05或P<0.01);校园绿地内乔木与乔草结构的植物群落,小气候改善能力优于乔灌草、灌草和草坪群落结构.从人体舒适度角度,建议在校园绿地建设中提高乔木与乔草结构植物群落的种植比例.

Analysis of Spring Microclimate and Human Comfort Effect in Campus Green Space

In order to study the impact of different plant community spaces on human comfort. The green spaces on the campus of Northeast Agricultural University were selected as the research object to collect microclimate data. Two-factor anova was used to compare the temperature, humidity, and temperature-humidity indices of five types of plant communities (arbor-shrub-lawn, arbor-lawn, shrub-lawn, arbor, lawn) in the spring (May). The results show that in the spring campus green spaces, different plant communities have certain adjustment ability for cooling and humidification; plant communities have better microclimate improvement ability than single lawn, and the difference is significant or extremely significant (P< 0.05 or P< 0.01); the plant communities of arbor and arbor-lawn structure in the campus green space has better microclimate improvement ability than the other three community structures. From the perspective of human comfort, it is recommended to increase the planting ratio of arbor and arbor-lawn structure plant communities in the construction of campus green space.
