GEOPROCESSAMENTO APLICADO Á ANÁLISE DOS IMPACTOS SOCIOAMBIENTAIS URBANOS: estudo de caso do bairro Santo Expedito em Buritizeiro/MG GEOPROCESSING APPLIED ANALYSIS TO ENVIRONMENTAL AND SOCIAL IMPACTS OF URBAN: a case study of the neighborhood in Santo Exp

RESUMO O presente trabalho procura associar as tecnicas de Geoprocessamento ao estudo dos impactos socioambientais oriundos da ocupacao espacial das cidades e sua continuada expansao. Analisando a situacao do municipio de Buritizeiro no Norte de Minas Gerais, cujo territorio e o 5o maior do Estado, enfatizando o bairro Santo Expedito, conjunto habitacional construido em 2007, situado na porcao SW (Sudoeste) da cidade.

Percebeu-se na area estudada a ocorrencia de impactos ambientais negativos como o deposito irregular de lixo residencial nas areas proximas ao bairro, principalmente na drenagem intermitente que cruza o mesmo ao meio em sentido geral NW/SE; entupimento do canal da referida drenagem; lancamento de esgoto residencial nas ruas do bairro e ausencia de pavimentacao.
