- W48250951 abstract "La zone centre-ouest du Senegal couvrant les regions administratives de Kaolack, de Fatick, de Kaffrine et une partie de la region de Tambacounda est marquee par un gradient pluviometrique croissant qui part de Kaolack (Ouest) vers l’Est de la region de Kaffrine (Koungheul). L’etude qui a eu lieu au niveau de la region de Kaffrine a ete faite en utilisant deux transects qui illustrent le zonage pedoclimatique et dans lesquels la caracterisation de la vegetation herbacee par la methode phytosociologique sigmatiste de Braun-Blanquet est effectuee dans quatre sites (Ngambou, Pete, Haffe Lour et Darou Miname). Des observations, sondages et profils pedologiques ont ete effectues tout le long des transects. Nous notons que la region de Kaffrine qui est une zone a vocation agro-sylvo-pastorale renferme une flore de 63 especes herbacees reparties dans 50 genres et 20 familles. La connaissance de cette strate herbacee est importante car elle constiue l’essentiel du fourrage, et aide a l’amenagement des parcours du betail. Les herbacees rencontrees dans la region donnent par analyse factorielle de correspondance quatre groupements vegetaux: le groupement a Tephrosia pedicellata a Haffe Lour qui a un sol a texture dominee par la fraction argilo-limoneuse et a fort taux de bases echangeables; le groupement a Ipomoea (I. pes-tigridis et I.vagans) a Ngambou sur des sols a fraction sableuse plus importante et a fort taux de bases echangeables; le groupement a Hyptis suaveolens a Pete sur des sols a texture sablo-argilo-limoneuse et a capacite d’echange cationique faible et le groupement a Panicum tenellum sur des sols sablo-argilo-limoneux a forte capacite d’echange cationique (CEC) de Darou Miname. Mots cles : Flore herbacee - groupements vegetaux - AFC - zonage pedoclimatique – phytosociologie The west central area of Senegal covering the administrative regions of Kaolack, Fatick, Kaffrine and a part of the Tambacounda region is marked by an increasing rainfall gradient. The area goes from Kaolack (West) to the east of Kaffrine region (Koungheul). This study is carried out at Kaffrine using two transects, showing pedoclimatic zoning, and in each one the characterization of the herbaceous vegetation by the phytosociological method is made in four sample of area (Ngambou, Pete, Haffe Lour and Darou Miname). Pedological studies have been conducted in each of these areas. The result shows that Kaffrine region, which is an agriculture, forestry and pastoral area, contains a flora of 63 herbaceous species distributed in 50 genera and 20 families. The herbaceous species met in the region give, by factorial correspondence analysis, four plants groups: the group of Tephrosia pedicellata at Haffe Lour, which soil texture is dominated by the clay-muddy fraction and with a high rate of exchangeable base. We found the group of Ipomoea (I. pestigridis and I. Vagans) at Ngambou, with an important sandy fraction soils and a high rate of exchangeable base, the group of Hyptis suaveolens at Pete with sandy-clay-muddy texture soils and a weak cationic exchange capacity. We found the group of Panicum tenellum at Darou Miname on sandy-clay-muddy soils and a strong cationic exchange capacity (CEC).
