Distribuição Diamétrica De Um Fragmento De Floresta Atlântica No Município De Santa Maria De Jetibá, Es

Abstract: Resumo. For the total population, the DBH distribution into 5 cm intervals formed 13 classes. The adjusted Meyer's equation reveals for this population a tendency to a J-inverse curve. The first three diameter classes from 5 to 20 cm concentrated 79% of the total population. Eight species had a population density with more than 40 trees per hectare. These trees were concentrated until the 40 cm distribution classes. The statistical analysis of the distributions curves reveals that these populations were distri… Show more

“…Meyer's exponential function was able to give an accurate estimation of the distribution of forest tree diameters, as noted in other studies related to tropical forests (Campbell et al, 1992;Imaña-Encinas et al, 2013;Lima et al, 2015;Lima et al, 2017) and temperate forests (Westphal et al, 2006;Kucbel et al, 2012). By assuming that a community in equilibrium must demonstrate a reverse J-shaped diameter distribution curve (Meyer, 1952), the study of this forest as a whole is balanced.…”

“…The diameter distribution can vary with site characteristics, such as aspect, slope, radiation, soil moisture, fertility (Felfi li, 1997;Imaña-Encinas et al, 2013;Orellana et al, 2014;Lima et al, 2015;Lima et al, 2017), and with forest management techniques (Vasconcelos et al, 2009). This information is important for the establishment of management plans for the even and uneven-aged forests, explaining age structure, regeneration strategies, wood harvesting methods, and others (Smith and Lamson, 1982;Campos et al, 1983;Campos and Leite, 2013;Souza and Soares, 2013).…”

“…A respeito da aplicação do modelo de distribuição diamétrica de Meyer, o alto valor observado para o R 2 assemelha-se aos bons indicadores de qualidade do ajuste equacional feito por Imaña-Encinas et al (2013). A densidade expressa pela equação ajustada apresentou uma subestimativa de 5,11% do total de plantas, superando os resultados de Orellana et al (2017).…”

“…Estes autores encontraram indicadores estatísticos consideravelmente menores para o R 2 , de modo que o modelo de Meyer não se ajustou satisfatoriamente à distribuição diamétrica observada por eles. O erro observado deve-se à variação da estimativa nas diferentes classes diamétricas, fenômeno também demonstrado por Imaña-Encinas et al (2013). Os parâmetros estatísticos permitem admitir que a equação obtida neste estudo é significativa para a população analisada.…”
