| Résumé : |
"A geoseries (or geosigmetum) is a catenal unit of vegetation series on an ecologically homogeneous phytotopographical unit of a given chorological sector. It includes the complete altitudinal sequence of zonal, extrazonal and intrazonal vegetation series. A geoseries can be divided into smaller sectors known as "geoseries individuals" on the basis of orography, hypsometry and aspect. Theoretically speaking, the geoseries individuals should be composed of the same number and type of series; however, in practice the number of sigmetamay vary for orographic, hypsometric and geological reasons. A geoseries is complete when it extends from sea level to an altitude of at least 3000 m (in the European mountains) and reduced if truncated at the top when the altitude range is less (lower massifs). Each geoseries is characterised by at least one vegetation series. A geoseries is bordered by geological, geomorphological and geographic limits (watershed line, watercourses, etc.). A geoseries can be mapped in three ways: 1) a single map unit including all the series and indicated with a single colour; 2) a map unit subdivided into series indicated with different colours; 3) a map unit divided into series indicated with different tones of the same colour. This method was used to produce a map (1:150,000) of the geoseries in the Val d'Adige (Central Alps) consisting of 6 climatophilous series and 3 edaphophilous series." (source : auteur) |
