Abstract  The distribution characteristics of spring dustfall during 2001\_2002 at 28 sites are analyzed in the east part of Northern China. The results show that the spring dustfall occur mainly in March and April with the amount of 127.05 t·km-2, occupying about 50% of the whole year dustfall; Spring dustfall are mainly from local region source, so the spatial distribution of dustfall is controlled mainly by the character of local underlying surface; Except for medium sand, the total dustfall and the amount of different grain size decrease exponentially with distance, and their “half-attenuation distance” decrease with the increase of grain size; The loss rate of the loess on China Loess Plateau was about 1×108 t·a-1 in Pleistocene, today it is about 14.4×108 t·a-1, and the Loess Plateau would disappear after 66 000 to 132 000 years if at this erosion rate.
Key words:  amount of dustfall      spatial distribution      dust transportation      loess accumulation
