Simulation Study on the Influence of Greening Rate of Urban Residential Clusters on the Distribution of Suspended Particulate Matters
Micro-climatic factors of landscape green space have provided dynamic conditions and thermal conditions for the distribution of suspended particulate matters.In this paper, the data of greening rate and micro-climatic factor of 88 residential areas were acquired, by means of field survey, spot test and CFD analog simulation.Through analysis of the previous relevant theoretical research and work,with the greening rate of residential clusters in Xian as the research object, this study has reasonably set the value of the greening rate and built the physical models of the greening rate.In this study, the relationship among the various factors was obtained by analyzing the measured data.Meanwhile, CFD numerical models were verified, and the influence of the greening rate on wind speed, turbulence characteristics and concentration of suspended particulate matters were simulated.Finally, it concluded that the optimal cluster plan is 35% and 40% greening rate, while the cluster plan of 0% and 25% greening rate is inappropriate.
