“…In this study, we performed in situ experiments with an orthogonal design to construct the mathematical model of wind erosion, from which the standardized regression coefficients of the main effects of the influencing factors on wind erosion were obtained in the following order: wind speed>vegetation coverage>soil moisture. The standardized regression coefficient of the main effect of wind speed was positive, while those of soil moisture and vegetation coverage were negative, indicating that increases in vegetation coverage and soil moisture can reduce wind erosion and that the greater the wind speed is, the more severe the wind erosion is (López et al, 2017). This finding also indicates that wind is a natural driving force of the formation and development of soil erosion, and wind speed initiates wind erosion.…”

The rapid desertification of grasslands in Inner Mongolia of China poses a significant ecological threaten to northern China. The combined effects of anthropogenic disturbances (e.g., overgrazing) and biophysical processes (e.g., soil erosion) have led to vegetation degradation and the consequent acceleration of regional desertification. Thus, mitigating the accelerated wind erosion, a cause and effect of grassland desertification, is critical for the sustainable management of grasslands. Here, a combination of mobile wind tunnel experiments and wind erosion model was used to explore the effects of different levels of vegetation coverage, soil moisture and wind speed on wind erosion at different positions of a slope inside an enclosed desert steppe in the Xilamuren grassland of Inner Mongolia. The results indicated a significant spatial difference in wind erosion intensities depending on the vegetation coverage, with a strong decreasing trend from the top to the base of the slope. Increasing vegetation coverage resulted in a rapid decrease in wind erosion as explained by a power function correlation. Vegetation coverage was found to be a dominant control on wind erosion by increasing the surface roughness and by lowering the threshold wind velocity for erosion. The critical vegetation coverage required for effectively controlling wind erosion was found to be higher than 60%. Further, the wind erosion rates were negatively correlated with surface soil moisture and the mass flux in aeolian sand transport increased with increasing wind speed. We developed a mathematical model of wind erosion based on the results of an orthogonal array design. The results from the model simulation indicated that the standardized regression coefficients of the main effects of the three factors (vegetation coverage, soil moisture and wind speed) on the mass flux in aeolian sand transport were in the following order: wind speed>vegetation coverage>soil moisture. These three factors had different levels of interactive effects on the mass flux in aeolian sand transport. Our results will improve the understanding of the interactive effects of wind speed, vegetation coverage and soil moisture in controlling wind erosion in desert steppes, and will be helpful for the design of desertification control programs in future.

“…Orchard land use will convert to the abandoned orchard if no management strategy implements to control wind erosion and movement of sand dunes to this land use. There are some practical options for preventing or reducing wind erosion, and some options for treating already eroding surfaces, where establishing and maintaining permanent vegetative cover (Musick & Gillette, ) and creating windbreaks (López, Valera, Molina‐Aiz, Lozano, & Asensio, ) work well in most areas affected by wind erosion. Few years ago, converting parts of the orchard land to the abandoned orchard also led to a significant decreasing in annual production of pistachio.…”

A geographic information system‐based land use impact model to map areas with risk for land degradation: Wind erosion as an example

Wind erosion modeling is hampered by the complexity of the relationships between factors involved in this process and the absence of comprehensive empirical data. In this study, we developed a geographic information system-based Land Use Impact Model and investigated its potential use for assessing the wind erosion risk in different land uses and wind geomorphic units. The obtained results were validated by field measurements and observations using a wind erosion simulator. Comparing the measured wind erosion intensities by the wind erosion simulator with those from the likelihood map obtained from the model revealed the high potency of the developed model for assessing land degradation due to wind erosion in our data scarce arid studied regions. Almost 90% of the mapping units in the likelihood map had similar wind erosion classes to the measured values. Furthermore, there was a high wind erosion occurrence risk in most parts of the studied regions (i.e., about 64% of the study area), and no mapping units in the study area were classified as 'very low' risk class. In addition, only about 9% of the surveyed mapping units were classified as a 'low' risk class, indicating an undesirable situation of the study area with regard to wind erosion.

“…In terms of ventilation, other works in the literature [35,36] have focused on the development of discharge coefficient models to explain the ventilation capacity of screened windows, as well as heat and mass transfer in the ventilation process. These discharge coefficients rely on the pressure drop coefficient, which requires to know beforehand the pore-related properties of the screen [37,38,39].…”
