摘要
以探讨西安市城区绿化覆盖率、绿化密度、绿化植被类型三者与空气中Pm^2.5浓度之间的关系为目的,选取了西安市区内7个监测点为代表点,测量范围为监测点方圆400m,约50万m^2.从2013年8 ～11月,历时4个月,每天获取监测点提供的PMt2.5浓度值.结果表明,提高总体绿化密度,采用适合的绿化植被种类,能够在一定程度上降低空气中的Pm^2.5浓度,提高空气质量.
The research mainly aims at exploring the relationship between green coverage and green types of Xi＇ an City with the PM2.5 readings by measuring green situations of seven selected points. The measurement range for monitoring points within a radius of 400 m, about 500 000 m^2. From August to November 2013 lasted for 4 months, the daily PM2.5 readings from the points are obtained. As the result, improving planting density and adopting right green type may help to reduce readings of PM2.5 and improve air quality.
