          Abstract

          Relationship in soil physical and chemical properties of soil, floristic and phytosociological association of semi-deciduous riparian forest of the Paranapanema River (R) and Rosana Reservoir (Re) in the Caiuá Ecological Station were evaluated. Aerial photography and satellite image were used to determine the forest cover and to locate 15 transects 50 x 30m (1500m²),which were used to sample trees with diameters at breast height (DBH)>15 cm. R contained 1487 individuals from 33 families, 64 genders and 73 species. The Shannon-weaver index (H') was 3.318. Re contained 1146 individuals from 35 families, 72 genders and 85 species and the H' was 3.755. There was a statistically significant difference (P<0.05) between R and Re environments and statistically significant correlations (p<0.05) were detected between soil physical attributes and Importance Values (IV) using the Detrended Correspondence Analysis (DCA).

          Das análises das propriedades física e química dos solos, da florística e da fítossociológica da vegetação arbórea de fragmentos da floresta estacional semidecidual localizados às margens do Rio Paranapanema (R) e do Reservatório de Rosana (Re) na Estação Ecológica do Caiuá (22°41'S e 52°55'W), verificou-se as correlações vegetação x solo. Utilizou-se fotografias aéreas e imagens de satélite para determinar a similaridade da cobertura florestal e alocar 15 transectos de 50m x 30m (1500m²) cada, amostrou-se os indivíduos com perímetro a altura do peito (PAP) 15 cm. No R amostrou-se 1487 indivíduos, de 33 famílias, 64 gêneros e 73 espécies e índice de Shannon-weaver (H') de 3,318. No Re registrou-se 1146 indivíduos de 35 famílias, 72 gêneros e 85 espécies e H' de 3,755. Os resultados mostraram ambientes estatisticamente diferentes e efetiva correlação entre os atributos físicos do solo e os Valores de Importância (VI) ordenados pela Detrended Correspondence Analysis (DCA).
