The impact of vegetation on the stability of dispersive material forming biancane badlands in Val d'Orcia, Tuscany, Central Italy.

摘要: Abstract The landscape of the Val d'Orcia is characterized by biancane badlands that have begun to be overgrown with vegetation in recent years, thus causing a loss landscape's biodiversity and cultural significance. aim this paper examine role associated soil properties on erodibility stability badlands. We attempt identify factors clearly distinguish bare slope area, where erosion particularly strong, from vegetated area typical biancana d'Orcia. data indicate decreased percentages exchangeable Na+ resulting less dispersive character material comparison area. Furthermore, exhibits an increased organic matter content enhanced water infiltration. Changes are probably due presence continuous cover enhances accumulation, infiltration, sodium leaching subsequently development. It concluded plays crucial altering form more stable conditions.
