摘　　要：针对通过绿化设计布局来缓解城市扬尘污染,降低空气颗粒物增加影响了人体健康这一内容,为了更好的设置出最合适的城市景观绿化布局,分析城市景观绿化设计布局对扬尘污染的弱化影响。计算不同类型尺度的绿化指标,确定景观优势元素和绿化类型的多样性标准。依据空气污染历史数据,获得扬尘污染质量浓度水平。经过实例分析可知,根据多样性标准设计的城市景观绿化布局能够弱化扬尘污染,且弱化效果随时间推移不断增强,城市污染预警次数下降,还能改变风速与扬尘间的正相关关系,降低二次扬尘污染,稀释了30%以上的污染浓度。In order to better establish the most suitable urban landscape greening layout and analyze the weakening impact of urban landscape greening design layout on dust pollution,this study aims to alleviate urban dust pollution and reduce the impact of increased air particulate matter on human health through greening design layout.It calculates greening indicators for different types of scales to determine the diversity standards for landscape advantageous elements and greening types.Based on historical air pollution data,the concentration level of dust pollution quality is obtained.Through example analysis,it can be seen that the urban landscape greening layout designed based on diversity standards can weaken dust pollution,and the weakening effect continues to strengthen over time.The number of urban pollution warnings decreases,and the positive correlation between wind speed and dust can be changed,reducing secondary dust pollution and diluting more than 30%of the pollution concentration.
