The soil macrofauna can be found in natural and anthropic environments, becoming one indicator of soil biodiversity and the intensity of biological activities. The objective of this study was to identify the main taxonomic groups of the soil macrofauna and his relation with seasonality in Cerrado soil use system environments. The research was carried out in the environments: Cerradão (CER), Mata dos Cocais (MDC), Cut and Burn (CAB), Eucalyptus (EUC) and Pasture (PAS) in Chapadinha, Brazil. Invertebrates were collected in the rainy season (RS) and in the dry season (DS), and identified the level order and / or family . Was found 1129 individuals in the rainy season, distributed in 14 taxonomic groups; and in the dry season, 1020 individuals in 11 taxonomic groups. Formicidae presented the largest number of individuals in two season. In the rainy season there was a greater number of taxonomic groups and individuals. The richness of organism did not vary significantly between environments and between sampling periods, and abundance showed differences between CER and EUC in both rainy and dry season. The number of taxon identified in the five environments was higher in MDC and EUC (rainy season), EUC and CAB (dry season). In relation the composition of the soil macrofauna, PERMANOVA indicated significance for the factors, environment and seasonality, as well as the interaction between both, showing different temporal variations in the sampled points. The non-metric multidimensional scaling of the environments in the seasonal periods for 'CAB-Dry' and 'MDC-Dry' showed differences in relation to the other environments. It is concluded that in the natural (CER and MDC) and anthropized (CAB, EUC and PAS) environments of the Cerrado biome, the soil macrofauna suffers alterations in the distribution of taxon influenced by the seasonality effect that contributes to the vegetation cover of the soil, increasing litterfall and creating new habitats for soil organisms. The Formicidae group was the most expressive in two seasonal periods, and its distribution was more representative in the dry season, because of being more tolerant to high temperatures.
