Spatial And Temporal Changes

The objective of this paper was to evaluate the degree of anthropic transformation of a river basin in the Amazon region. We used the digital data of the TerraClass Project to calculate the Anthropic Transformation Index - ATI. In order to verify spatial and temporal changes along a decade in the Gurupi river basin, we used the database of the years 2004 and 2014. The results showed an increase of anthropic changes in the basin over a decade, as a result of forest cover conversion into agricultural and pastures areas. Although the Gurupi river basin remains at a regular level of degradation after a decade, the intensification of land use and land cover change is a threat to the few rainforest remnants of the river basin, which can lead the region to the next level of degradation, if effective forest protection, conservation and restoration actions are not implemented in the region.

Landscape Types

Spatial and temporal changes of landscape pattern in Li River basin was analyzed based on Landsat TM and OLI data in 1991 and 2013. Maximum likelihood classification method was used to extract land use information in two periods. In FRAGSTATS platform, the characteristics of landscape types were quantitatively analyzed by selecting landscape index at class level and landscape level. Results showed: (1) the area of forest landscape increased significantly, while shrub and bare rock decreased obviously. (2) landscape types were characteristic of high inner homogeneity and low heterogeneity. (3) the evolution of landscape pattern was significantly affected by human activities and social factors.
