| Sumario: | The State Park of Turvo - PET is located in the northwest of the State of Rio Grande do Sul, in the municipality of Derrubadas, and is a Conservation Unit of Integral Protection, having great importance for representing the last remnant of considerable size of the seasonal deciduous forest in the south of Brazil (SEMA, 2005). The objective of the work is the geomorphological characterization and temporal dynamics of meteorological data for the PET, which are combined to analyze the phytosociological distribution of the seasonal deciduous forest present in the PET. For this purpose, phytosociological field surveys were conducted using the SRTM digital terrain model to calculate the geomorphology and meteorological data of precipitation and temperature of the GIOVANNI platform. Meteorological variables such as precipitation and temperature are directly related to the distribution of biomes and forest typologies. The topographic modeling of the PET made it possible to analyze the characteristicsof the relief. The data obtained with topographic modeling allowed us to conclude, through the study carried out of the declivity and altimetry and the slope orientation variables, that the relief of the PET is mostly flat to wavy. Through the orientation of slopes, it was possible to verify that there is no large predominance of orientation directions. The smaller altimetric classes are the areas closest to the edge of the park area, where the Uruguay River passes. Analyzing the phytosociological data measured in the field and the topographic modeling, it is concluded that among the species present on the plots, the most characteristic is the jerivá. In most sampled plots, the plant has been shown to adapt well, regardless of altitude and slope. |
