Abstract

Wind erosion and dust storms are common phenomena in the semi-arid Xilingele grassland (Inner Mongolia) and contribute considerably to matter balances. Based on wind erosion measurements in spring 2005 and 2006 the organic carbon and total nitrogen contents of dust were analyzed to determine the contribution of wind erosion processes on C- and N-ratios to the grasslands. The great range of dust emission and deposition at the different grazing intensities underlines the sensibility of the grassland. The 2 years of measurement show the high annual variability of dust storm processes. This variability shows that single very strong events can determine the net balance of a whole year
