Nowadays, using nature and its healing effects, as one of the sustainable architectural solutions, has attracted the attention of urban designers and managers. The aim of this study is to identify and prioritize the characteristics affecting the healing design of sustainable medical spaces, as one of the urban infrastructures, especially in interaction with nature. The mixed methodology of this study  consists of four steps. First, characteristics effective in healing through medical spaces were investigated through library study method and by reviewing past research. ،Then, using Delphi method, and by interviewing and asking experts through Likert method, the final characteristics were identified, prioritized, and inferentially analyzed using the SPSS software. Third, as a case study, the method and application of these characteristics in real samples were analyzed inferentially. Finally, using the results obtained, a practical model for designing a healing center was presented. The results from Delphi method reveal experts' prioritization of 10 healing characteristics in the design of  medical spaces. The Fresults obtained from the Delphi section and the SPSS inferential analysis reveal a high mean for the elimination of stressors (4.8) and the interaction with nature (4.6), and a low mean for horticultural activities (2.4). The findings of the case study and inferential analysis also indicate ahigh mean  for the elimination of stressors(3) and interaction with nature(3) and a low average of spatial design for privacy(1). Finally, by combining and comparing the results of different steps of the research, and by considering the prioritization of characteristics, a  practical model is presented for the healing design of  medical spaces, especially in interaction with nature. This model can be extended to other infrastructures of sustainable urban spaces.

The relationship between man and nature and its importance in the urban environment is one of the issues considered by theorists and planners in the field of urban space for a long time. However, human beings as the basis for this relationship have  jeopardizing this vital interaction by making changes in cities for some time now. One of the significanr in human communication and the redidence in cities is his satisfaction by climate conditions. The outdoor thermal comfort is affected by the built environment, land cover, plant evapotranspiration, and other factors present at the site. In this study, among the ways of promoting thermal comfort in urban space, the use of plants is focused on. In this article, the effects of plants on temperature and relative humidity were firstly analyzed in a case study. Then, using Envi-met software, an existing urban block was simulated by placing hypothetical trees and another hypothetical block was simulated as well. According to the results, the air temperature in the places, which were very close to the nearly 50-cm plants, was obtained to be almost 0.5◦C lower than other places. In addition, the relative humidity within the studied limits was higher. Therefore, the effects of these two factors on improving the thermal comfort of urban microclimates, especially in hot seasons, could be well evidenced. The assessment of different types of plants also showed that the temperature adjustment could be achieved regardless of plant type.

One of the most important problems in the field of agricultural activities is water scarcity or water resources issues. In this context, only those countries that utilize scientific methods in supplying the water needed for crops have been able to overcome these problems. In this study, we tried to evaluate the application of meteorological studies in estimating the water requirements of the desired crops (wheat and potato) in Tabriz region during different stages of growth. For this purpose, the ETP (plant evapotranspiration potential) was first determined using long-term statistics, and then, using the FAO organization tables, the plant coefficients for each of the crops were extracted. Finally, in order to plan for the supply of water resources, the effective rainfall in the region has been studied, and by subtracting the amount of water required from effective rain, the amount of water deficiency in the region has been identified.
