校园不同绿地类型对温湿效应的影响

The Effects of Reducing Air Temperature and Increasing Humidity on Different Green Spaces of College

选择宜春学院校园内的草坪,灌草和乔灌草等绿地类型,利用温湿度表,测量分析各绿地内的温湿度变化和对温湿度影响的差异。乔灌草绿地日温变化较缓,且其日温最高值出现于16点,其它绿地日温变化较大,其日温最高值出现于14点,与大气的日气温高点一致。湿度是由高到低再升高的过程。对于温度,与水泥地相比,乔灌草类的绿地最高温度平均下降了9.4℃,灌草类下降了7.4℃,草坪下降了3℃。对于湿度,与水泥地相比,乔灌草的最低湿度平均增加了24.8%RH,灌草的湿度增加了17.6%RH,草坪增加了10.4%RH。结果表明,草坪型、灌草型和乔灌草型的绿地都有降温增湿的作用,乔灌草类的绿地降温增湿效果最明显。

The effect of reducing air temperature and increasing humidity by different green space were tudied in yichun college and the difference of reducing air temperature and increasing humidity among of them were ana- lyzed. The temperature of all kinds of green space types appeared to change from low to high then becane low a- gain, While the humidity appeared to change from high to low then became high again. Compared with cement land, the highest average air temperature of arbor - bush - grass, bush - grass and grass were 9. 4℃, 7.4℃ and 3℃ lower respectively, the lowest average of humidity were 24. 8% , 17.6%, 10. 4% higher respectively. The re- suits showed that all kinds of green space alleviate temperature and increase humidity while green land of arbor - bush -grass is the best.
