REYES RODRIGUEZ, Claudia Fabiola et al. Analysis of the land surface temperature in the green areas of Durango city, state of Durango. Rev. mex. de cienc. forestales [online]. 2024, vol.15, n.81, pp.83-109.  Epub 13-Maio-2024. ISSN 2007-1132.  https://doi.org/10.29298/rmcf.v15i81.1432.

The green areas in urban areas have provided a variety of ecosystem services which influence the quality of life of the inhabitants. The objective of this work was to analyze the effect of green areas on the Land Surface Temperature (LST) recorded by remote sensors in the city of Durango, Durango. The existing public and private green areas in the city were differentiated and the area in square meters per inhabitant was calculated. A classification by land use (urban, body of water, bare soil and green area) was carried out in order to analyze the ST derived from Landsat 8 satellite images and geographic information systems (QGIS), in addition a comparison of ST in three types of green areas (parks, squares and gardens, and ridges). The behavior of the ST was analyzed in two seasons of the year, in winter 2021 and spring 2022, identifying the areas with the highest incidence of temperature in two periods. The results indicate a lower ST in green areas compared to urban areas (concrete, construction and asphalt areas), as well as a regulatory trend in larger green areas (parks). The ST satellite product allowed to evaluate the temperature in spaces with vegetation within an urban area and it is shown that the larger the green area, the more thermal regulation exists in urban areas.
