With the development of urbanization in recent years. One of the ways to reduce the effects of microclimate change is to evaluate the effect of planting vegetation on parameters affecting mi-croclimate, including air temperature, average radiant temperature, relative humidity and wind speed. This research was conducted with the aim of investigating the planting pattern of differ-ent trees in the east-west intersection of two residential building blocks in Sabzevar region. In order to achieve the goal of the research, different modes of tree planting are modeled in ENVI-met software and factors affecting microclimate and thermal comfort index of PET are analyzed and investigated. The results and findings of the research indicate that 2 outer rows of decidu-ous trees with a height of 10 meters and a crown width of 5 meters and a middle row of non-deciduous trees with a height of 18 meters and a crown width of 11 meters in summer and 1 upper row of deciduous trees With a height of 11 meters and a crown width of 9 meters and a lower row of evergreen coniferous trees with a low leaf density index, with a height of 15 me-ters and a crown width of 7 meters, they create favorable conditions in terms of comfort in Sab-zevar climate in winter. The reason for this is the provision of the required humidity and more shading in the first pattern due to the planting of one more row of trees than in the second pat-tern, and the closer environmental conditions to the comfort zone in the summer season. On the other hand, in the second alternative, the use of grass and deciduous trees with a low height in the central courtyard has increased the average radiant temperature and increased the PET index in winter.
