Resumo: | The restoration success in forest ecosystems can be adequately assessed by correct selection of indicators that represent the achievement of established goals. The discriminant analysis technique on indicators selection consists of separation and classification of new observations on pre-defined groups, reducing the number of variables that are discriminant functions linearly dependent of the original variables. This study aims to define an index composed by structural attributes (number of species and individuals planted, height, basal area, number of regenerant species and individuals) and chemical and pedological soil attributes to classify riparian reforested environments regarding to restoration taking as reference reforestation around the the Volta Grande reservoir, Minas Gerais State, Brazil. Eleven variables were used for previous classification of plots in partially restored or unrestored groups and also used for discriminant analysis. Variables selected by the discriminant function generated were: number of species and basal area of planted individuals, number of regenerant species and individuals litter accumulation and soil cation exchange capacity. Compatibility of 98% from previous plot classifications and after index formation, show the representativeness of the selected variables on evaluation of restoration of riparian reforestations. |

A seleção pela técnica da análise discriminante consiste da separação e classificação de novas observações em grupos previamente definidos, reduzindo o número de variáveis, que são funções discriminantes linearmente dependentes das variáveis originais. O presente estudo objetiva definir um índice composto por atributos estruturais (número de espécies e indivíduos plantados, altura, área basal, número de espécies e indivíduos regenerantes) e atributos químicos do solo e pedológicos, para classificar reflorestamentos em ambientes ciliares, com relação à restauração tendo, como base, reflorestamento no entorno do reservatório da Usina Hidrelétrica de Volta Grande, MG. Onze variáveis foram utilizadas para a classificação prévia das parcelas nos grupos, como parcialmente restauradas ou não restauradas, e na análise discriminante realizada em seguida. As variáveis selecionadas pela função discriminante gerada foram: número de espécies e área basal dos indivíduos plantados, número de espécies e indivíduos regenerantes, acúmulo de serapilheira e capacidade de troca de cátions do solo. A compatibilidade de 98% entre a classificação prévia das parcelas e após a formação do índice demonstram a representatividade das variáveis selecionadas na avaliação da restauração dos reflorestamentos dos ambientes ciliares estudados.Embrapa Florestas2014-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/75710.4336/2014.pfb.34.80.757Pesquisa Florestal Brasileira; v. 34 n. 80 (2014): out./dez.; 375-389Pesquisa Florestal Brasileira; Vol. 34 No. 80 (2014): out./dez.; 375-3891983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/757/401Reis, Daniele Nogueira dosDavide, Antonio ClaudioFurtado Ferreira, Danielinfo:eu-repo/semantics/openAccess2017-04-28T12:49:00Zoai:pfb.cnpf.embrapa.br/pfb:article/757Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2017-04-28T12:49Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |

The restoration success in forest ecosystems can be adequately assessed by correct selection of indicators that represent the achievement of established goals. The discriminant analysis technique on indicators selection consists of separation and classification of new observations on pre-defined groups, reducing the number of variables that are discriminant functions linearly dependent of the original variables. This study aims to define an index composed by structural attributes (number of species and individuals planted, height, basal area, number of regenerant species and individuals) and chemical and pedological soil attributes to classify riparian reforested environments regarding to restoration taking as reference reforestation around the the Volta Grande reservoir, Minas Gerais State, Brazil. Eleven variables were used for previous classification of plots in partially restored or unrestored groups and also used for discriminant analysis. Variables selected by the discriminant function generated were: number of species and basal area of planted individuals, number of regenerant species and individuals litter accumulation and soil cation exchange capacity. Compatibility of 98% from previous plot classifications and after index formation, show the representativeness of the selected variables on evaluation of restoration of riparian reforestations. |
