Facade vertical greening arrangement method and system based on CFD environment numerical simulation

The invention discloses a facade vertical greening arrangement method and system based on CFD environment numerical simulation, and the method comprises the steps: obtaining meteorological data of a position region where a target building is located, and setting working conditions in a preset building initial model according to the obtained meteorological data; wherein the building initial model is established in CFD software; adjusting vertical green plant parameters on the target building, and constructing a comparison model; according to the comparison model, simulating building microenvironments of the target building under different vertical greening layouts, and obtaining thermal comfort indexes of surrounding pedestrian layers of the target building under different vertical greening layouts; and selecting an optimal vertical greening layout on the target building according to the obtained thermal comfort index. According to the invention, a suitable and comfortable wind and heat environment around the
