Resumo: | The renewable natural resources sustain the balance between the man and the nature. The destruction of one of those resources represents the unbalance and the man's future destruction. Such resources accomplish a social function to the man's service and of the society. Starting from the moment that the man began to use the renewable natural resources in their multiple forms, the environmental impact was felt by the environment. The breaking in the normal patterns of the natural resources is what one can call environmental impact. Then, the environmental impact is the alteration in the middle or in some of their components for certain action or activity. Those alterations need to be quantified, therefore they present relative variations, could be positive or negative, big or small. The objective of studying the environmental impacts is, mainly, evaluating the consequences of some actions, so that it can have the prevention of the ambient certain quality that can suffer the execution of certain projects or actions, or soon after the implementation of the same ones. This evaluation had been consisted in two stages: the first one, with the analysis of the variables environmental factors and actions proposed by Leopold-Rocha's matrix (2002), and the second one, for the grouping analysis for the WARD method, with the statistical package SAS SYSTEM 8.2. THE degree of medium real deterioration obtained by Leopold-Rocha's matrix had been 29%, showing that the referred place is quite deteriorated, once the acceptable environment deterioration tax is 10%. In the grouping analysis for the WARD method it had been possible the separation of the proposed actions in two different groups (A and B). The A group is constituted by: regime modification; land transformation and constructions; and other, with magnitude (11,63%) and importance (17,64%) average, being the actions group that cause more impact in the micro-basin. It was also possible the separation of groups of environmental factors in three different groups (A, B and C). The C factors group (cultural factors: aesthetic and of human interest) it had been presented the highest average in relation to the magnitude (9,91%) and to the importance (13,86%), denoting to be the environmental factors group that more suffered by the human action. In that aspect, the objective of this work had been consisted of evaluating the micro-basin deterioration degree of Vacacaí-Mirim river, that is in the DNOS dam shore (National Department of Works and Sanity) in Santa Maria, RS, and to recommend reliever and compensatory measures for the recovery of the environment of the place. |

A destruição de um desses recursos representa o desequilíbrio e a futura destruição do homem. Tais recursos cumprem uma função social a serviço do homem e da sociedade. A partir do momento que o homem começou a usar os recursos naturais renováveis em suas múltiplas formas, o impacto ambiental foi sentido pela ambiência. O rompimento nos padrões normais dos recursos naturais é o que se pode chamar de impacto ambiental. Então, o impacto ambiental é a alteração no meio ou em algum de seus componentes por determinada ação ou atividade. Essas alterações precisam ser quantificadas, pois apresentam variações relativas, podendo ser positivas ou negativas, grandes ou pequenas. O objetivo de se estudar os impactos ambientais é, principalmente, o de avaliar as conseqüências de algumas ações, para que possa haver a prevenção da qualidade de determinado ambiente que poderá sofrer a execução de certos projetos ou ações, ou logo após a implementação dos mesmos. Esta avaliação consistiu de duas etapas: a primeira, com a análise das variáveis fatores ambientais e ações propostas pela matriz de Leopold-Rocha (2002), e a segunda, pela análise de agrupamento pelo método WARD, com o pacote estatístico SAS SYSTEM 8.2. O grau de deterioração real médio obtido pela matriz de Leopold-Rocha foi de 29%, mostrando que o ambiente encontra-se bastante deteriorado, uma vez que a taxa aceitável de deterioração na ambiência é de 10%. Na análise de agrupamento pelo método WARD foi possível a separação das ações propostas em dois grupos distintos (A e B). Constituem o grupo A: modificação do regime; transformação do território e construções; e outros, com média de magnitude (11,63%) e importância (17,64%), sendo o grupo de ações mais impactante na microbacia. Também foi possível a separação de grupos de fatores ambientais em três grupos distintos (A, B e C). O grupo C de fatores (fatores culturais: estéticos e de interesse humano) foi o que apresentou a média mais alta em relação à magnitude (9,91%) e a importância (13,86%), denotando ser o grupo de fatores ambientais mais impactados pela ação antrópica. Nesse aspecto, o objetivo deste trabalho consistiu em avaliar o grau de deterioração da microbacia hidrográfica do rio Vacacaí-Mirim que se encontra a montante da barragem do DNOS (Departamento Nacional de Obras e Sanidade) em Santa Maria, RS, e recomendar medidas mitigadoras e compensatórias para a recuperação da ambiência da mesma.Conselho Nacional de Desenvolvimento Científico e Tecnológicoapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Engenharia FlorestalUFSMBRRecursos Florestais e Engenharia FlorestalImpactos ambientaisMicrobaciaRio Vacacaí-MirimMatriz de leopold-rochaAnálise de agrupamentoEnvironmental impactsMicro-basinVacacaí-Mirim riverLeopold-rocha s matrixGrouping analysisCNPQ::CIENCIAS AGRARIAS::RECURSOS FLORESTAIS E ENGENHARIA FLORESTALImpactos ambientais na microbacia do rio Vacacaí-Mirim em Santa Maria - RS.info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisRocha, José Sales Mariano dahttp://lattes.cnpq.br/1616648249059070Baracuhy, Jose Geraldo de Vasconceloshttp://lattes.cnpq.br/7627825287233640Madruga, Pedro Roberto de Azambujahttp://lattes.cnpq.br/6881563409114963http://lattes.cnpq.br/4807525329153013Gracioli, Cibele Rosa5002000000034003005005005006b76cc83-1cbd-49a3-b2f7-f30bc0ee11c175ead22c-c8e0-4995-8a7c-f8f783caa01b0b56d35b-c389-43f8-a2a4-5e61f9bb07f43cd76448-fb79-4eef-964a-72648182483cinfo:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALCIBELE GRACIOLI.pdfapplication/pdf1519971http://repositorio.ufsm.br/bitstream/1/8612/1/CIBELE%20GRACIOLI.pdfd635699ee53b691cf3e0bfc3b0976f45MD51TEXTCIBELE GRACIOLI.pdf.txtCIBELE GRACIOLI.pdf.txtExtracted texttext/plain228080http://repositorio.ufsm.br/bitstream/1/8612/2/CIBELE%20GRACIOLI.pdf.txta47718a202c16db8401615e2da6152f2MD52THUMBNAILCIBELE GRACIOLI.pdf.jpgCIBELE GRACIOLI.pdf.jpgIM Thumbnailimage/jpeg5579http://repositorio.ufsm.br/bitstream/1/8612/3/CIBELE%20GRACIOLI.pdf.jpg209e12894c9c582f23473901046ab819MD531/86122021-10-21 10:13:59.611oai:repositorio.ufsm.br:1/8612Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2021-10-21T13:13:59Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |
