【摘要】 通过对西宁市城区不同绿化带的增湿效应测定分析,结果表明:与对照点相比,乔木-灌木-地被绿化带类型日平均湿度增加了6.20%;乔木-灌木绿化带类型日平均湿度增加了5.15%;乔木绿化带类型日平均湿度增加了3.27%。乔木-灌木-地被类型增湿效应最好,其次是乔木-灌木类型,乔木类型虽具有一定的增湿效应,但是效果较差。不同绿化带类型的增湿效应存在明显差异,相关系数R2为0.801。更多还原

【Abstract】 Analyze the effects of air humidity increase 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 increase in average daily humidity 6.20%;the type of arbor-shrub increase in the average daily humidity 5.15%;the type of ground cover plant increase in average daily humidity 3.27%.The effects of air humidity increase 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 and humidity,but its influence was slight.There were also significant differences among the different urban green land,and the correlation coefficient(R2) with increasing humidity was 0.801.更多还原
