Abstract:

Soil wind erosion activities have become increasingly frequent in Northeast China, posing serious threats to agricultural production and ecological security. To reveal the characteristics of aeolian sand activity intensity in Northeast China, fixed-point observations were carried out during the spring tillage period on bare land, stubble farmland, and grassland in a typical wind erosion region of Northeast China. The characteristics of sand-driving winds, drift potential, and wind erosion force were systematically analyzed. The results showed that: (1) During the observation period, the mean wind speed at a height of 2 m was 2.89 m·s-1, and wind speeds at different heights exhibited a fluctuating decreasing trend, with the prevailing wind direction being NW. (2) The mean sand-driving wind speeds on bare land, stubble farmland, and grassland were 6.33 m·s-1, 7.04 m·s-1, and 8.78 m·s-1, respectively, while the corresponding sand-driving wind frequencies were 19.15%, 12.94%, and 4.39%. The sand-driving wind directions were mainly concentrated between E and NW. (3) During the observation period, the study area was characterized by a low wind energy environment. All three land-use types exhibited moderate directional variability, corresponding to a blunt bimodal wind regime, and the resultant drift direction was NE. Both drift potential and wind erosion force followed the order: bare land > stubble farmland > grassland. These results provide a scientific basis for the implementation of wind erosion control projects and the protection and sustainable utilization of land resources.

Key words: Northeast China, aeolian sand activity intensity, sand-driving wind, drift potential, wind erosion force
