Abstract:: Study of soil particle size characteristics in desertification area can provide certain theory basis for the regional desertification control and ecological construction. Study on soil grain size characteristics in five different land use types (mobile sand dunes, grass square barrier, Haloxylon ammodendron, Nitraria tangutorum community, Artemisia ordosica community) and fractal dimension in the northeastern margin of Ulan Buh Desert through the field sampling and laboratory experiments was carried out. The results showed that: (1) the content of fine sand was greater than else size fraction sand in the pilot site which was fluctuated between 66.49%～81.54%, and the content of fine sand was the lowest in the five sample plots(0.58%～1.72%). The contents of different size particles decreased in the order: fine sand > middle sand > mighty fine sand > coarse sand>silt sand; (2) the fractal dimensions of five sampling plots were significantly different (p < 0.01), and the fractal dimensions decreased in the order: Artemisia ordosica community sample area(1.72) > Nitraria tangutorum community sample area(1.56) > Haloxylon ammodendron sample area(1.44) > mobile sand dunes(1.40) > grass square barrier(1.37); the fractal dimension was positively correlated with the percentages of silt sand and mighty fine sand (p < 0.01), was negatively correlated with percentage of fine sand (p < 0.05), was not significantly correlated with percentage of middle sand and coarse sand (p > 0.05); (3) The areas growing natural vegetation are characterized as the good vegetation coverage and soil granule is finer, as a result, we should increase the protection of natural vegetation in order to prevent the occurrence and development of the soil wind erosion in this area.
