Abstract：Obvious dust events had not occurred in China’s eastern Loess Plateau in 2012, so dustfall in this period main derived from non-duststorm. Extensive dustfall collections were carried out from January through December of 2012 in China’s eastern Loess Plateau. The results show that the annual mean dustfall was about 89.27t/(km2×a) for the study region. About 53.69%, 22.45%, 8.44%, and 15.42% for the dustfall was collected, respectively, in the spring (March to May), summer (June to August), autumn (September to November), and winter (January, February, and December). The variation in dustfall in a large spatial scale was controlled mostly by climate background, but in local area was influenced by local factors, such as geomorphology, hydrological condition, soil, and vegetation coverage; the seasonal variation in dustfall was influenced mostly by wind speed, but high precipitation and NDVI index have also reduced dustfall. In modern climatic background, the dustfall in each season all mainly came from local region in the study area, but dustfall contained comparatively more dust came from far sources. The dustfall in the Loess Plateau also suggested that modern climate may is in a relatively warm-wet period of interglacial stage, and the climate in penultimate and last glacial stage may be similar with which in March and April of modern western Loess Plateau, but the climate in penultimate and last interglacial stage may similar to the climate in May and June of modern eastern Loess Plateau.
