[Objective] To explore the wind and sand flow prevention and stabilization benefits of artificial Haloxylon ammodendron forests with different planting years, as well as to rapidly evaluate the wind and sand flow prevention and stabilization benefits, and to define the lower limit of the biomass-anti-sand flow prevention and stabilization benefits, so as to provide scientific basis for the restoration and reconstruction of desert vegetation. [Methods] In this study, the artificial Haloxylon ammodendron forests with different planting ages in the desertification area of Turpan City were used as the research object, and various indicators of wind and sand prevention and fixation benefits were monitored through the methods of field investigation, field observation and indoor analysis to compare the relationship between the indicators of wind and sand prevention and fixation benefits and the changes of biomass. [Results] (1) The windbreak effectiveness, surface roughness, surface erosion volume, and sand retention benefits of artificial Haloxylon ammodendron forests are gradually improved with the increase of the years of creation. (2) The wind speed profile in the region changed with the growth of the artificial Haloxylon ammodendron forests. The wind speed profile of the primary desert showed “L” type change characteristics, the wind speed profile of the 2-year old and 4-year old artificial Haloxylon ammodendron forests showed “I” type change characteristics, the wind speed profile of the 6a-year old and 8a-year old forests showed “J” type change characteristics. The wind speed contours of 6-year old, 8-year old and 10-year old planted Haloxylon ammodendron forests showed the opposite of “J” type changes. (3) The sand transport flux of the planted Haloxylon ammodendron forest showed a decreasing trend with the increase of the establishment period, and also showed a decreasing trend with the increase of the height. (4) In this study, the biomass-windbreak and sand fixation efficiency index model was constructed based on five kinds of Haloxylon ammodendron forests with different years of age, in which the best function model between the standing biomass index and the relationship between windbreak efficiency, soil erosion volume, surface roughness, sand transport flux, and sand blocking efficiency was the power function model, the idempotent function model, quadratic function, exponential function, and the logistic function model, and the R2 were respectively 0.651, 0.962, 0.790, 0.804, 0.925.(5) If we want to play a good windbreak and sand fixation benefit, the lower limit of standing wood biomass index of the artificial shuttle forest needs to reach 4.92kg/m2.[Conclusion] To play the role of windbreak and sand fixation of the windbreak and sand fixation forests, the planting years of the artificial Haloxylon ammodendron forest after 4 years, its windbreak and sand fixation benefit can reach a good state, and at the same time, using the At the same time, the corresponding model can be used to quickly estimate the regional indicators of windbreak and sand fixation benefits, and carry out the assessment of windbreak and sand fixation benefits. When the standing wood biomass index of the planted Haloxylon ammodendron forest reaches 4.92 kg/m2 and above, it will be able to realize its good sand-control and sand-fixation benefits.
