Model Research on the Impact of Tree Greening Layout with Wind-responsive Characteristics on the Wind Environment in Residential Areas

Abstract

With the concept of living environment put forward, creating a comfortable, healthy and energy-saving living environment has attracted more attention. The optimization of wind environment is of positive significance for urban ecological livability and alleviating urban heat island effect. Considering the wind-induced response of trees, this paper uses computer simulation technology to explore the distribution of flow field around greening in different building spaces and layout forms, and puts forward the optimization strategy of greening layout around buildings. The research shows that different building environments will also have a certain impact on the wind environment behind trees. Roof greening is more complicated than the wind field around buildings, and the wind-induced deformation of trees is obvious, and the wind reduction rate is higher. In addition, considering the influence of wind-induced response on trees, different planting spacing has different wind reduction efficiency. The proportion of ideal wind speed area in different horizontal layout forms of trees from large to small is row, enclosure and row.
