Urbanization is a major anthropogenic alteration that involves dramatic changes in environmental conditions. Urban heat island (UHI)is a thermic phenomenon where urban-associated modified conditions increase local air and surface temperatures, affecting ecosystem processes and services, human health and well-being, and has been linked to social-economic factors and urbanizing patterns. A surface UHI (SUHI) assessment for Montevideo, Uruguay, was perfomed combining a Landsat-based high-resolution land surface temperature map and a long term neighbourhood level assessment, and explored causes and drivers of the phenomenon. Additionally, social-ecological attributes were analyzed at the neighbourhood level, linking ecosystem services (ES) estimations to social-economic census data. SUHI scaled linearly with impervious surface at the neighbourhood level. ES showed patterns consistent to a young city with marginalized population settling on the rural edge of the urbanization gradient. This work contributes to the body of urban studies by bringing novel information from an under-represented regional social-ecological context.

蒙得维的亚城市生态学入门：拉丁美洲社会生态背景下的热岛


城市化是一种重大的人为改变，涉及环境条件的巨大变化。城市热岛（UHI）是一种热现象，其中与城市相关的条件改变增加了当地空气和地表温度，影响生态系统过程和服务、人类健康和福祉，并与社会经济因素和城市化模式有关。乌拉圭蒙得维的亚的地表城市热岛 (SUHI) 评估结合了基于 Landsat 的高分辨率地表温度图和长期社区水平评估，并探讨了这一现象的原因和驱动因素。此外，还对社区层面的社会生态属性进行了分析，将生态系统服务（ES）估计与社会经济普查数据联系起来。 SUHI 与邻里层面的不透水表面呈线性比例。 ES 显示出与年轻城市一致的模式，边缘化人口定居在城市化梯度的农村边缘。这项工作通过从代表性不足的区域社会生态背景中带来新颖的信息，为城市研究做出了贡献。
