Assessing drought severity for the purposes of ecological studies and forest management using bioclimatic indices
Appréhender le niveau de sécheresse dans le cadre des études stationnelles et de la gestion forestière à partir d'indices bioclimatiques
Résumé
This article presents the different sources of climatological data available for the forester. A summary of the bioclimatic indices useful for ecological studies and forest management are presented as well as three simple equations for calculating potential evapotranspiration (PET): Thornthwaite, Turc, Hargreaves. Mean annual potential evapotranspiration values for the period 1961-1990 was calculated using GIS, mapped and compared for the whole of France
