摘　　要：为了设置出最合适的城市景观绿化布局,缓解城市扬尘污染,降低空气颗粒物浓度,减少空气污染,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;通过城市景观绿化设计布局优化,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 establish the most suitable urban landscape greening layout,alleviate urban dust pollution,reduce air particle concentration,and reduce air pollution,this study analyzes the weakening impact of urban landscape greening design layout on dust pollution.It calculates the greening indicators for different types of scales,and determines the diversity standards for landscape advantageous elements and greening types.The concentration level of dust pollution quality is obtained based on historical air pollution data.Through case analysis,it can be concluded that urban landscape greening layouts designed according to diversity standards can weaken dust pollution,and the weakening effect continues to enhance over time.By optimizing the layout of urban landscape greening design,the positive correlation between wind speed and dust can be changed,reducing secondary dust pollution and diluting pollution concentrations by more than 30%.
