Previous issue date: 2017-06-30 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (CAPES) / A cobertura vegetal oferece diversos benef?cios para a sociedade, mas historicamente vem sendo suprimida pela ocupa??o antr?pica em ?reas urbanas. A an?lise de sua distribui??o, quantifica??o e qualifica??o oferecem subs?dios para a avalia??o da qualidade ambiental. Os estudos sobre a cobertura vegetal do munic?pio de Natal s?o escassos, mas pesquisas sobre esse tema s?o importantes, pois possibilitam um diagn?stico da situa??o atual dessa cobertura para que planos de interven??o sejam aplicados de maneira mais sustent?vel. O objetivo da pesquisa foi analisar a cobertura vegetal do munic?pio de Natal a partir da sua quantifica??o, qualifica??o e distribui??o espacial. Os procedimentos metodol?gicos consistiram na quantifica??o e mapeamento da distribui??o da cobertura vegetal para o munic?pio de Natal e no mapeamento da diversidade da cobertura vegetal por interpreta??o visual em quatro bairros, sempre a partir da classifica??o de imagens do Google Earth PRO. Constatou-se que Natal possui 4.626 hectares de cobertura vegetal, distribu?dos em 153.891 fragmentos. Mais de 60% da ?rea de cobertura vegetal est? localizada nas Zonas de Prote??o Ambiental (ZPAs) da cidade e 83% dos fragmentos apresentam ?reas menores que 100 m?. Foi verificado que Natal apresenta um ?ndice de Cobertura Vegetal de 27,5% e 54,2 m? de cobertura vegetal para cada habitante. Em rela??o aos quatro bairros selecionados para an?lise da diversidade da cobertura vegetal, verificou-se que os bairros com tecido urbano cont?nuo, Cidade Alta e Petr?polis, possuem uma cobertura vegetal predominantemente antropizada e uma menor diversidade de classes de cobertura vegetal, 17 classes, enquanto que os bairros com tecido urbano descont?nuo, Pitimbu e Paju?ara, apresentaram maior percentual de cobertura vegetal natural e uma maior diversidade de tipos de cobertura vegetal, 40 classes. Conclui-se que Natal ainda apresenta uma cobertura vegetal significativa, por?m mal distribu?da sobre o territ?rio, mais concentrada e diversa nas ?reas perif?ricas, sobretudo nos bairros com presen?a de ZPAs, e mais fragmentada e antropizada nas ?reas centrais. / The vegetal cover offers several benefits to society, but historically it has been suppressed by anthropic occupation in urban areas. The analysis of its distribution, quantification and qualification offers subsidies for the evaluation of environmental quality. The studies about the vegetal cover of the municipality of Natal are scarce, but research about this theme is important, because they make it possible to diagnose the current situation of this coverage so that intervention plans are applied in a more sustainable way. The objective of the research was to analyze the vegetal cover of the municipality of Natal from its quantification, qualification and spatial distribution. The methodological procedures consisted in the quantification and mapping of the distribution of the vegetal cover for the municipality of Natal and mapping the diversity of vegetal cover by visual interpretation in four neighborhoods, always from the classification of images of Google Earth PRO. It was verified that Natal has 4,626 hectares of vegetal cover, distributed in 153.891 fragments. More than 60% of the vegetal cover area is located in the Environmental Protection Areas (ZPAs) of the city and 83% of the fragments have areas smaller than 100 m?. It was verified that Natal presents a Vegetal Cover Index of 27.5% and 54.2 m? of vegetal cover for each inhabitant. In relation to the four neighborhoods selected for analysis of the vegetal cover diversity, it was verified that the neighborhoods with continuous urban fabric, Cidade Alta and Petropolis, have a predominantly anthropic vegetal cover and a lower diversity of vegetal cover classes, 17 classes, while the neighborhoods with discontinuous urban fabric, Pitimbu and Paju?ara, presented a higher percentage of natural vegetal cover and a greater diversity of vegetal cover types, 40 classes. It is concluded that Natal still presents a significant vegetal cover, but poorly distributed over the territory, more concentrated and diverse in the peripheral areas, especially in neighborhoods with the presence of ZPAs, and more fragmented and anthropized in the central areas.
