摘要
通过对西宁市城区不同绿化带的降温效应测定分析,结果表明:与对照点相比,乔木-灌木-地被绿化带类型日平均温度降低了1.45℃;乔木-灌木绿化带类型日平均温度降低了1.39℃;乔木绿化带类型日平均温度降低了0.79℃。乔木-灌木-地被类型降温效应最好,其次是乔木-灌木类型,乔木类型虽具有一定的降温效应,但是效果较差。不同绿化带类型的降温效应存在明显差异,相关系数R2为0.815。
Analyze the effects of temperature reduce by different green land in urban area of Xining,The results showed that： compared with the control point, the type of arbor-shrub-ground cover plants reduce the daily average temperature of 1.45 ℃ ;the type of arbor-shrub reduce the daily average temperature of 1.39 ℃; the type of ground cover plant reduce the daily average temperature decrease of 0. 79℃. The effects of temper- ature reduce in the arbor-shrub-ground cover plant were the best,The second was the arbor - shrub type,The ground cover plants could regulate air temperature, but its influence was slight. There were also significant differences among the different urban green land, and the correlation coefficient （R2） with reducing tempera- ture was 0. 815.
