Abstract

Shelterbelts are of great significance to reducing wind and sand disasters and improving and restoring the ecological environment in arid areas. In order to optimize the configuration of shelterbelts in arid areas, this study used Pinus sylvestrwasvar. Mongolica and Haloxylon ammodendron as research objects, and designed two forest belt models of No. 1 and No. 2. through wind tunnel tests, analyze the sediment transport, wind erosion rate, and dust distribution characteristics of belts with different configurations. The results show: (1) both soil sediment transport and wind erosion rate increased with the increase of wind speed. Under low wind speeds, the No. 2 forest belt had the least amount of sediment; under high wind speeds, the 20-year-old forest belt of the No. 1 belt had the smallest amount of sediment; (2) Under the same wind speed, the 20-year-old forest belt had the lowest soil wind erosion rate, and the 5-year-old forest belt had the highest soil wind erosion rate. (3) The 20-year-old of No. 1 belt had a stronger ability to block sand, and the amount of dust fall at each point behind the belt was smaller than that of the bare ground. The research results can provide a theoretical basis for the optimization of the ecological environment in the arid area of the Mongolian Plateau.
