Resumen
This study discusses the application of a phytostructural methodology to characterize the structure of the vegetation in the area of Vila Real (Northern Portugal). With this objective, eight different types of plant communities representative of the apparent states of the successional process present in this area were selected. The phytostructural methodology was elaborated from three types of structural basic matrices: diversity, abundance and cover. The data obtained were collected in a contingency matrix, which was the object of a statistical multivariate analysis. Three structural tendencies emerged from this analysis. With the aim of characterizing the stability of their respective structures, the results are discussed in terms of resistance and resilience, according to the Highest Expressive Amplitude (HEA) concept and using the intra and inter-communitary structural dynamic as the structural parameters.
