AMARAL, Rubens et al. Bases for urban landscape planning: Hyperespectral images use for identification of areas providing support ecosystem services. CIDADES [online]. 2020, n.41, pp.71-89. ISSN 2182-3030.  https://doi.org/10.15847/cct.20152.

The consideration of ecosystem services in landscape planning can both prevents and mitigate environmental impacts on the territory, an objective that is achieved through services that are related to the provision of resources and regulation of the environment, providing socio-cultural well-being. But such services are anchored in the integrity of the ecosystem achieved by ecological support functions that, in turn, have their best expression in the presence of vegetation and the ability to uptake carbon in the landscape. This understanding demands that territorial planning consider and have the means to measure the presence of these services to support their decisions on land use and occupation. The present work aims to identify carbon sinks in the territorial landscape of the Federal District, using remote sensing tools to support territorial planning based on the promotion and protection of ecological support functions and, as a result, of the ecosystem services (regulation, provision and culture). In order to identify areas with carbon sink behavior, the ICO₂ and CO₂flux indices were applied to a portion of the landscape of the Federal District, one linked to the presence of CO₂ in the atmospheric column and the other to the vegetation photosynthetic efficacy. In the results analysis, a relationship between the indices was observed, in the identification of carbon sinks, and evidence of the vegetation performance in the provision of ecosystem support services was provided, pointing out the relevance of the hyperspectral indices to subsidize the territorial planning.

Keywords : ecosystem services; territory; urban planning; remote sensing; carbon sinks.
