Obtention avec ordinateur de cartogrammes de parametres de fertilité édaphique de quelques régions calcarieres du bassin

Abstract

Des èchantillons de sols des provinces de Salamanca et Valladolid ont été analysés afin d´obtenir des paramètres de fertilité édaphique. La représentation graphique spatiale des résultats a été matérialisée de deux manières. -Dans le cas de prise d´echantillons représentatifs de facon systématique dans chaque région (un échantillon pour 400 ha), les cartogrammes pour chaque paramètre ont été réalisés avec un programme d´ordinateur, assignant à chaque graticule du cartogramme la valeur du paramètre. Dans le cas d´existence d´une banque de données aléatoires dans une région on a obtenu la moyenne des valeurs assignées a chaque graticule lorsqu´il y avait plusieures valeurs: ou dans le cas contraire, on a assigné une valeur par interpolation, lorsqu´il n´y avait pas de valeur dans le graticule. en les cartogrammes pour chaque paramètre ont été réalisés.
