Dynamic-zonal phytosociology as landscape science
The first strict geomorphological interpretation of the landscape and its apparent homogeneity are ideas which were rapidly abandoned by phytosociologists and substituted by dynamic and topographic conceptions of the landscape. The attempt to relate and order the phytocoenotic diversity of the landscape with topographic and successional criteria has produced new phytosociological disciplines influenced by these dynamic and zonal concepts (symphytocoenology or symphytosociology), which nowadays represent one of the most attractive challenges of vegetation science. For that reason, each generation of phytosociologists tries to contribute their experiences and criteria to the development of such an important subject (Braun-Blanquet 1928; Tüxen 1956, 1973, 1978, 1979; Schmithüsen 1959, 1968; Bolós 1963; Béguin & Hegg 1975; Géhu 1976; Rivas-Martínez 1976, 1977, 1987; Géhu & Rivas-Martínez 1981; Béguin & Theurillat 1984; Foucault 1986; Schwabe 1990; Ansseau & Grandtner 1991; etc.).
