Variabilidade espacial de atributos do solo e vegetação do "Parque Natural Municipal Tamarino de Avila Silva", município de Clevelândia, Paraná

Abstract

For many years, the society evolves supported by a very fragile environmental base from which it extracts its food, fiber, and mineral resources. In the interface of this development, forests have been devastated, soils and rivers contaminated, and the balance of biodiversity altered. In this sense, the Tamarino de Ávila Silva Municipal Park becomes a good example of inadequate exploitation of the soil. Because, for approximately 10 years, it was used as a landfill, receiving waste generated in the urban area of the City of Clevelândia - PR. Currently the area is in the process of forest recovery and, concomitantly, soil contamination has been receding. In this sense, the intensity of the forest degradation process was analyzed, as well as the dynamics of its recovery through remote sensing and photosynthetic attributes of the vegetation and the impact of the contribution of organic material on the chemical characteristics of the soil. For the study of forest dynamics, sentinel satellite images from the period between 2016 and 2020 were used and based on the use of spectral indices. Soil chemical attributes were based on the collection of samples in transects and analyzed the contents of Ca, Mg, K, P, Al, as well as the values of base saturation, aluminum saturation and cation exchange capacity through the method of geostatistical estimation (Kriging-ordinary). Observing the thematic maps it is possible to establish a likelihood between the NDVI pattern and the regions where fertility is lower, also enabling the establishment of management zones and recovery of native forest, contributing to the implementation of a recovery plan of this area and future work.
