          Abstract

          Resumo A legislação florestal brasileira, principal instrumento legal sobre proteção e restauração da vegetação natural, sofreu significativas mudanças nas últimas décadas. Tais mudanças afetam diretamente os biomas do país. Nesse contexto, o presente trabalho teve por objetivo avaliar se, com a edição da Lei Estadual nº 18.104, de 18/07/2013, houve alteração na composição da cobertura vegetal na região da Chapada dos Veadeiros - Goiás, no período de 2008 até 2018, que corresponde aos cinco anos anteriores e posteriores à promulgação da referida lei. Foi adotada uma metodologia quantitativa na qual as hipóteses são testadas a partir da coleta de dados, baseando-se em variáveis que possuem medição numérica. Buscou-se fazer uma análise estatística para configurar padrões de modo a comprovar ou refutar a hipótese de que a Lei Florestal afetou as diferentes tipologias vegetais na região da Chapada dos Veadeiros. Foi verificada uma tendência de redução das áreas de formação savânicas e campestre na região estudada e aumentos significativos das áreas cobertas por florestas plantadas, pastagens e agricultura. Não foram observadas diferenças significativas estatisticamente nas áreas com formação florestal. Esses resultados apontam que a edição da Lei nº 18.104/2013 pode ter favorecido alterações nas áreas cobertas por diferentes tipologias vegetais na região da Chapada dos Veadeiros - Goiás, reduzindo áreas de formação savânica e campestre e ampliando áreas cobertas por florestas plantadas, pastagens e agricultura.

          Abstract Brazilian forestry legislation, the main legal instrument on the protection and restoration of natural vegetation, has undergone significant changes in recent decades. Such changes directly affect the country's biomes. In this context, the present work had as objective verify if, with the edition of the Forest Law of Goiás, nº 18,104/2013, there was a change in the composition of the vegetation cover in the region of Chapada dos Veadeiros - Goiás, in the period from 2008 to 2018, which corresponds five years before and after the enactment of the law. A quantitative methodology was adopted in which the hypothesis are tested based on the data collection, based on variables that have numerical measurement. An attempt was made to perform a statistical analysis to configure standards in order to prove or disprove hypothesis that the Forest Law affected the different plant typologies in the Chapada dos Veadeiros region. There was a tendency to reduce the areas of savanna and grassland formation in the studied region and significant increases in the areas covered by planted forests, pastures and agriculture. There were no statistically significant differences in areas with forest formation. These results indicate that the enactment of Law No 18,104/2013 may have favored changesin the areas covered by different plant types in the cover in the region of Chapada dos Veadeiros - Goiás, reducing areas of savanna and grassland formation and expanding areas covered by planted forests, pastures and agriculture.
