RUBIANO, Kristian. Distribution of the green infrastructure and its thermal regulation capacity in Bogotá, Colombia. Colomb. for. [online]. 2019, vol.22, n.2, pp.83-100. ISSN 0120-0739.  https://doi.org/10.14483/2256201x.14304.

Cities show particular environmental characteristics that give rise to phenomena such as heat islands. Although vegetation covers are key in mitigating these adverse conditions, their distribution has been found to be inequitable. Analyzing this distribution and the supply of ecosystem services is important for the city planning . For this reason, the distribution of the thermal regulation capacity of the public vegetation covers of Bogotá city was analyzed, using tree coverage and greenness as proxy variables, through geostatistical analysis, Geographic Information Systems and remote sensing. There was an increase in the average greenness of the parks according to their size and the socioeconomic stratum where they are located, the tree coverage increased in the highest strata. Coldspots and hotspots of these variables and the thermal regulation potential were identified in the areas with the lowest and highest strata, respectively.

Keywords : tree canopy cover; normalized difference vegetation index; environmental inequity; urban heat island; urban parks; urban ecosystem services..
