Quantificação do estoque de carbono fixado em reflorestamentos de Pinus na área de domínio da floresta ombrófila mista no Paraná

Abstract

This paper, developed in the Mixed Araucaria Forest (F.O.M.), in Parana State, aimed at detecting the main carbon stock spots in forest plantations in the limits of the ecosystem, as well as estimating the amount of carbon being fixed by their biomass of these stands. A total of 22 CBERS and LANDSAT satellite imagery scenes were used for this purpose. Most of them came from 2004. The visual interpretation of the forest plantation stands inside the study area (F.O.M.) was carried out taking into account several criteria. Stand growth and yield simulation were carried out for pine plantations, the dominant genus in the study site, by using the SISPINUS software. Hence, it was possible to relate stand volume in different age classes to the biomass amount fixed by them. Subsequently, the spatial information was treated and summarized by meso-region adopted by the Paraná Sate Government, so that the comprehension of the carbon values became easier. The reforestation area interpreted summed 516,163.58 ha, and the total carbon stock was estimated at 26,726,950.2 t C or 97,999,708.2 t of CO2 equivalent.
