COBERTURA DA TERRA E QUALIDADE AMBIENTAL DA BACIA HIDROGRÁFICA DO CÓRREGO VILA PINHEIROS, CURITIBA, PARANÁ.

Abstract

The fragmentation and suppression of vegetated areas and the increase in waterproofed areas in cities contribute to a decrease in environmental quality. The objective of the study was to perform an assessment of the environmental quality of the Vila Pinheiros watershed, located in Curitiba/Paraná, based on land cover. Orbital images provided by Google Earth Pro and Google Street View, year 2018, were used, in scales approximately between 1:3,000 and 1:5,000, using the court as the minimum area. The mapping was done in a non-automatic way in the ArcGis software, version 10.4.1. and, subsequently, the environmental dynamics of the basin were analyzed, generating the environmental quality map. It was found that 66.19% of the basin consists of built-up spaces; with buildings with up to 4 floors with vegetation in the adjacent areas occupy 46.62% of the basin. The best levels of environmental quality represent 4.04% of the total area studied, are composed of no-built spaces with shrub and herbaceous vegetation, and exposed soil. The worst environmental quality indexes in the basin are concentrated in the southeast, east and northeast regions, representing about 4.05% of the total area. These data point to a low environmental quality in the studied basin.
