Abstract


This paper aimed to show the potential use of GIS as an auxiliarytool in studies on phytosociology and dynamics of natural forests. A spatialdata model was made base on measured dendrometric features and the spaceposition of the trees carried out at an experimental area of the NationalForest of Irati, Paraná State, Brazil. The area has six hectars and is formed by Araucarian Forest in 24 experimental blocks of 0.25 hectars each. It waspossible to visualize the spacial distribution of different tree species of thisexperimental area, as well as to stablish relationship between different speciesand their atributes through spacial consulting, by logic or boolean expressionand by groups. The study showed that spatialization of a continuous largesampling area of this forest in a GIS facilitates interpretation of itsfisionomics and structural features. Elsewhere, allows detailed analysis thatturns phytosociological and dynamical interpretation easier.
