Influence du paysage sur la flore adventice en viticulture

Abstract : This research paper suscribes in thesis which identifies main variables influencing weed flora in vineyards. We focused here on landscape composition and structure identifiying as a potential filter. We investigated what radii has the most important influence on weed richness and how it was affected by the landscape surrounding each fields. We mapped landscape around 77 vineyards fields to get landscape composition and structure with GIS tools. Weed richness has been recorded in 2015. Weed richness is high in vineyards with 218 species identified. Vineyards prevailed on landscape surrounding sample (from 50% to 89% depending radii). Weed richness is best explained by 100m radius. It’s negatively influenced by vineyards rate and field size. Biodiversity increased with slope, woods and edges superficies. Thus, landscape heterogeneity increased weed biodiversity.
