Aiming at the problem that the previous methods cannot accurately capture the characteristic factors, which leads to poor observation effect, a numerical simulation method for observing the microclimate characteristics of urban mountain greenway is proposed. According to the microclimate operation mechanism of urban mountain greenway, the spatial comfort is adjusted by the way of ecological environment protection. Envi-met three-dimensional microclimate numerical simulation is used as the main observation tool, and the basic conditions of numerical simulation are set up. Based on Envi-met software model structure, input/output parameters are set, and file format is imported into Envi-met image processing software to obtain three-dimensional model map. By using the open side boundary condition, the observational items are obtained, and the sensible heat flux and latent heat flux are calculated, and their variations are analyzed. The observation of microclimate characteristics is completed and the observational results are corrected. Experiments were carried out under the instrument of microclimate observation tower.
