Facing the concern of the population to its environment and to climatic change, city planners are now considering the urban climate in their choices of planning. The use of climatic maps, such Urban Climate Zone‑UCZ, is adapted for this kind of application. The objective of this paper is to demonstrate that the UCZ classification, integrated in the World Meteorological Organization guidelines, first can be automatically determined for sample areas and second is meaningful according to climatic variables. The analysis presented is applied on Toulouse urban area (France). Results show first that UCZ differentiate according to air and surface temperature. It has been possible to determine the membership of sample areas to an UCZ using landscape descriptors automatically computed with GIS and remote sensed data. It also emphasizes that climate behavior and magnitude of UCZ may vary from winter to summer. Finally we discuss the influence of climate data and scale of observation on UCZ mapping and climate characterization.
面对人们对环境和气候变化的关注，城市规划者现在在规划选择中考虑城市气候。气候图的使用，如城市气候区划（UCZ），就适应于这种应用。本文的目的是证明世界气象组织指南中集成的 UCZ 分类，首先可以自动确定样本区域，其次根据气候变量具有意义。所提出的分析应用于图卢兹市区（法国）。结果表明，UCZ 根据空气和地表温度进行区分。已经可以使用 GIS 和遥感数据自动计算的景观描述符来确定样本区域对 UCZ 的归属。它还强调了 UCZ 的气候行为和幅度可能会从冬季到夏季发生变化。最后，我们讨论了气候数据和观测尺度对 UCZ 制图和气候特征的影响。
