Managerial evaluation of medicinal plant species in green area with environmental design in Mashhad municipality

Increasing soil carbon sequestration, in addition to increasing plant biomass, production and improving soil fertility, also has a beneficial role in green space development and landscape management. In this study, in order to evaluate the carbon sequestration project in Khorasan Razavi province of Mashhad city, based on sampling from soil depths of 0-15 cm, soil physical and chemical traits and plant traits were calculated based on field and laboratory measurements. In the step, by sampling of aerial and aerial plants as well as litter, the weight of aerial biomass carbon, the weight of biomass carbon after E and the weight of litter carbon in the soil and water laboratory are determined. Finally, with the total carbon content of soil, plants and litter, the amount of carbon sequestration per user per square meter is determined. After these steps, the database was prepared in EXCEL and SPSS software. In the comparisons, it is found that the components and chemical components have a significant difference at the 95% confidence level. The results showed that the percentage of soil organic carbon in the use of Atriplex (1.76) is higher than other applications, followed by the use of rosemary (1.71). The results of three-use carbon sequestration also showed that most of the cases were related to Mohammadi flower for 6 years and Mohammadi planting project was successful in increasing carbon sequestration in Mashhad areas. Also, the results showed that 3200 lands from the study area in terms of physiography and water resources have the potential to develop green space with the first priority. The use of rosemary in addition to the high ability of carbon sequestration, in the development of green space is also an acceptable efficiency.
