Análise ambiental da sub-bacia do Ribeirão do Lipa, em Cuiabá - MT

Abstract

In this study, it was sought to perform an environmental analysis of the Ribeirão do Lipa subbasin, which integrates part of the Cuiaba river basin, important contributor to the Alto Paraguay or Platina hydrographic basin. The Ribeirão do Lipa cuts the Urban Macrozone from the Cuiabá city, extending into the rural zone, where its headwaters are localized. The subbasin area totalizes 6.309,24 hectares, and for this study completion, the same was divided in thirteen micro basins. These regions were characterized, according to a supervised classification, by the usage of the image from the satellite SPOT 5, having being determined nine classes of soil usage and occupancy: savannah changed, native cerrado, riparian forest, degraded area, exposed soil with recovering vegetation, exposed soil, mesh water, urbanization and pavement. These classes were grouped in five themes addressed by the VERAH method, which are: vegetation, erosion, residue, water/siltation and habitation/occupancy, determining, based on that, the environmental diagnostic from the Ribeirão do Lipa subbasin.
