IMAGENS AÉREAS NA AVALIAÇÃO DA EXPANSÃO DAS MATAS CILIARES NUMA BACIA HIDROGRÁFICA COM SOLO ARENOSO

Abstract

Remote sensing, through its products, offers a view of changes in land use and
vegetation cover over time. Enabling the identification of deforestation, urbanization, climate change
and other environmental impacts. Soil manipulation may be related to inadequate management of
natural resources, resulting in soil exposure and loss of its original structure. Using the soil
appropriately, using agronomic techniques with contour lines, cultivation using the direct planting
system, liming and other preservation actions can minimize erosive effects. Riparian forests were
raised to reduce the speed of surface runoff and stabilize the soil, in addition to increasing water
infiltration into the soil and biodiversity. A research focused on the evaluation of the riparian forest
in the Anhembi-SP basin in the last ten years of intensive eucalyptus cultivation, comparing aerial
images from 2023 with previous surveys carried out in 2013. A specific regeneration and expansion
of the riparian forests was observed during the period analyzed, associated with the replacement of
native pastures by perennial crops, such as eucalyptus, which was considered beneficial for the
environment and for the conservation of sandy soils in the area of river influence.
