[Objective] This study aimed to reveal the soil texture difference and water-holding capacity change characteristics of four typical parts of blowout pits in the Hulunbuir grassland.[Methods] The blowout pits were divided into four parts: the edge area（A area）, the sand pit area（B area）, the severe sand accumulation area（C area）, and the mild sand coverage area（D area）. The natural grassland was used as the control（CK area）. Correlation analysis and PCA analysis of soil properties including soil particle size, bulk density, water-holding capacity, etc. in the 0-200 cm soil layer of each pit were carried out.[Results] 1) The soil in the 0-200 cm soil layer of blowout pits in the Hulunbuir grassland was mainly medium sand, there was no gravel, and the average particle size was B area（1.41Φ）＞A area（1.48Φ）＞C area（1.52Φ）＞D area（1.98Φ）＞CK area（2.45Φ）. 2) There were significant differences in soil particle size parameters of the four parts of the blowout pits. The sorting coefficient was generally poor, the peak value was sharp and narrow, the skewness was extremely positive, and the fractal dimension was generally distributed around 2.1-2.2. 3) The average particle size gradually decreased along the main wind（northwest wind）. The sorting effects of C and D were stronger, while the sorting effects of A and B were weaker. 4) Soil bulk density of wind erosion pits was between 1.55-1.70 g/cm³, soil water content was CK area（4.51%）＞A area（4.4%）＞D area（4.35%）＞B area＞（4.23%）＞C area（4.2%）, and field water-holding capacity was CK area（17.97%）＞D area（16.95%）＞A area（15.53%）＞B area（15.26%）＞C area（14.51%）. 5) Soil water content in different parts of blowout pits was positively correlated with clay, silt, fine sand, and very fine sand fractions, and negatively correlated with medium sand, coarse sand, and very coarse sand fractions.[Conclusion] The overall average particle size of blowout pits becomes finer along the main wind direction. Water-holding capacity is the weakest in the C area, and strongest in the D area. The findings provide a theoretical basis for the management of blowout pits.
