Abstract

Cities located in arid areas are facing several risks that threaten their sustainability due to the effects of climate change and urbanization, and the resulting consumption inequality and depletion of natural resources. There are many variables that determine the urban-building form, which, in turn, affects energy consumption in cities. Therefore, the goal of this work is to condense the information provided by the urban-building morphological variables into just a few variables or combinations for the urban blocks located in the six departments of Mendoza’s Metropolitan Area (MMA). Methodologically, quantitative data of the spatial distribution of urban-building variables were considered, their correlations were calculated, and a Principal Component Analysis was applied to synthesize the number of variables. The results identify the Building Density, Building Separation, and Normalized Difference Vegetation Index (NDVI) as the main variables of the first principal component, in five of the six departments of the MMA. The first two are related to the built environment, and the third is to vegetation. By including data on urban tree cover, available only for the Capital department, the results include the tree-cover magnitude, completeness, and transmissivity variables, together with those already identified in the first three components. The findings of the work provide information on the representative urban-building variables of the oasis city that will allow, in the future, establishing intervention priorities considering a reduced number of synthetic variables, to propose efficiency and energy generation strategies.
阿根廷门多萨都市区城市形态的主要组成部分分析
由于气候变化和城市化的影响,以及由此产生的消费不平等和自然资源枯竭,干旱地区的城市面临着威胁其可持续性的若干风险。决定城市建筑形式的变量很多,而城市建筑形式又反过来影响城市的能源消耗。因此,这项工作的目标是将城市建筑形态变量提供的信息浓缩为位于门多萨都市区(MMA)六个部门的城市街区的几个变量或组合。在方法上,考虑城市建设变量空间分布的定量数据,计算变量间的相关性,运用主成分分析法对变量数量进行综合。结果表明,建筑密度、建筑间隔和归一化植被指数(NDVI)是第一主成分的主要变量,在气象局6个部门中有5个部门。前两个与建筑环境有关,第三个与植被有关。通过纳入仅为首都部门提供的城市树木覆盖数据,结果包括树木覆盖大小、完整性和透射率变量,以及在前三个组成部分中已经确定的变量。这项工作的结果提供了关于绿洲城市的代表性城市建筑变量的信息,这将允许在未来考虑到减少合成变量的数量,建立干预优先事项,提出效率和能源生产战略。
