在这项研究中，我们提出了一个模型构建方法的基础上的主要环境因素（气候，地形/岩性和土地利用）的层次整合，确定分布的spur-thighed龟在西班牙东南部。关于该物种存在/不存在的数据主要基于对牧羊人的采访中获得的信息。分层建模工作包括三个步骤。首先，我们使用气候变量构建了整个区域的模型，从而获得了潜在的气候模型。其次，我们引入了气候分布范围内的地形和岩性变量（潜在模型）。第三，以第二个模型为出发点，我们包括土地利用变量，以获得实际的分布模型。
In this study we propose a model‐building approach based on the hierarchical integration of the main environmental factors (climate, topography/lithology, and land uses) determining the distribution of the spur‐thighed tortoise in south‐east Spain. Data on the presence/absence of the species were primarily based on information derived from interviews to shepherds. The hierarchical modelling exercise consisted of three steps. First, we constructed a model for the entire region using climate variables, thus obtaining a potential climatical model. Second, we introduced variables referring to topography and lithology that fall within the climatic distribution range (potential model). Third, by using this second model as a starting point, we included land use variables to obtain the actual distribution model.
