摘要: Abstract The results of an experiment to evaluate the effect rainfall characteristics on organic carbon (OC) losses and type particles mobilised by erosion under natural different land uses (non-disturbed forested area, a non-irrigated olive cropland) at plot scale are presented. Labile (particulate carbon, POC) stable (mineral associated MOC) pools were measured in soil sediments. Based product total I30 (mm mmh−1), as measure erosivity, events divided into three classes (from low high erosivity). A positive correlation between P*I30 OC concentration (r = 0.54, p
