Abstract

In recent decades, in third world countries, especially in the Middle East, the concept of urban micro-climate has undergone many changes in the process of development and construction, leading to environmental crises and the discrete structure of energy consumption in urban blocks. The urban form, the product of morphological changes in recent periods, has had significant effects on the micro-climate of the city. The city of Tabriz in the cold and dry areas of Iran has suffered from the inadequacies of the urban form and adverse effects on the micro-climate of the city as a result of unbalanced development. The main aim of research as parametric study on the interactions between urban morphology and microclimate is to investigate density metric to analysis effect amount in micro-climates. The research is analytical-descriptive and method of collecting data in the form of documents includes literature review, modeling and simulation using Envi-met software and density metric explain modes of a hypothetical in 10 scenarios and are presented in the form of two groups. The construction parts of the hypothetical areas are located in the urban area of Tabriz city, Iran. All scenarios were assumed to be in the same area configuration, where buildings are located in 25 plots of 40 m x 40 m. The result shows Investigation the average ratings obtained from microclimatic simulation of the first group of scenarios shows that by keeping FAR constant and changing BSC, one cannot expect a specific sequence of changes in microclimatic parameters in the space around the buildings but in the case of the second scenario group which is presented with constant BSC and variable FAR, there is a significant sequence in the order of the obtained ranks and the change trend in the average parameters. The results show scenario A2 with FAR 1 and BSC 40% with the lowest average value (3.5) of the total of four parameters of simulating the hottest and coldest day has achieved the best result and is introduced as the best scenario. For future researches, it is possible to propose a more focused investigation on each of the mentioned parameters. DOI: https://doi.org/10.52783/pst.544

城市形态中的密度因素对寒冷和干旱地区微气候参数的影响研究（案例研究：伊朗大不里士市）

近几十年来，在第三世界国家，特别是中东地区，城市微气候的概念在发展建设过程中发生了许多变化，导致了环境危机和城市街区能源消耗结构的离散化。城市形态作为近代形态变化的产物，对城市微气候产生了重大影响。伊朗寒冷干燥地区的大不里士市由于发展不平衡，城市形态不完善，对城市小气候产生了不利影响。作为对城市形态与小气候之间相互作用的参数研究，研究的主要目的是通过密度指标来分析小气候的影响量。该研究是分析描述性的，以文件形式收集数据的方法包括文献综述、使用 Envi-met 软件进行建模和模拟，以及密度指标解释 10 种假设情景的模式，并以两组形式呈现。假设区域的建筑部分位于伊朗大不里士市城区。结果显示，对第一组方案进行微气候模拟所获得的平均等级调查表明，如果保持容积率不变，同时改变 BSC，则无法预期建筑物周围空间的微气候参数会出现特定的变化顺序，但在 BSC 不变、容积率可变的第二组方案中，所获得的等级顺序和平均参数的变化趋势有明显的顺序。结果表明，在模拟最热和最冷天的四个参数中，FAR 值为 1、BSC 值为 40%、平均值最低（3.5）的方案 A2 取得了最佳结果，被列为最佳方案。在今后的研究中，有可能对上述每个参数进行更有针对性的调查。DOI: https://doi.org/10.52783/pst.544
