Abstract :

Background and Objective: An important achievment to urban stability is enjoyment of healthy and wellbeeing environment and having enough green space. While the urban forests do the best performance among different groups of green spaces, therefore, evaluating of this topic, is one of the important methods for solving of environmental problems.Material and Methodology: This study will pay attention to check of the quantitative and qualitative status and comparison of two regions of Tehran with the goal of obtaining information for the conservation and optimal development of green space. Collecting the data, were conducted through the field operation and systematic randomly sampling. Totally, 83 plots in two regions have been determined. Then, descriptive indices, adaptive tables of statistical tests for assessing and comparing of quantity and quality of trees in these two regions have been used.Findings: The results indicated that there was a significant difference in the crown cover of urban forests between two regions with no significant difference in other traits. Results showed buttonwood (Platanus orientalis) had highest frequency within two regions. There was a positive and significant correlation between traits like, plots with height, diameter at breast height, main collar diameter, number of tree in plot and number of roots.Discussion and Conclusion: While there weren't any difference between succulence of trees in two regions, results showed the highest level of freshness in regions 1 were obtained by oak (Quercus macranthera), white berry (Morus alba) and Poplar (Populus nigra)  and in 5 regions regarding to acacia (Robinia Pseudoacacia) and  trees of heaven (Ailanthus altissima) were  respectively. Therefore, the species listed for the development of urban forests in these areas can be investigated.
