地球上大约50%的沙漠被石质表面覆盖，而不是沙丘。石质表面通常通过面积分数和粗糙度因素的影响阻挡或减少矿物粉尘气溶胶的排放。结合这些石材覆盖效应对气候和环境建模研究至关重要。在野外观测的基础上，利用两个回归公式和一些常量，将石料覆盖效应结合到东亚地区的沙尘模拟模型中。双回归方案假设石头的粗糙度密度可以从SoilGrids 2.0数据集的粗碎片分数中得到。从数据集来看，蒙古西部和准噶尔地区的石质覆盖度较高，中国戈壁沙漠和黄土高原的石质覆盖度较低。因此，该模型在高覆盖区域重现的粉尘气溶胶较少，而在低覆盖区域重现的粉尘气溶胶较多。这一模拟结果与世界气象组织目前的天气报告和卫星气溶胶观测结果一致。改进后的模型再现了土壤可蚀性的多样性，在性能统计上具有良好的平衡性。本研究是作者所知的第一次使用真实的石头覆盖图成功地研究了石头覆盖对沙尘暴模拟的影响。
Approximately 50% of the Earth's deserts are covered with stony surfaces, not dunes. The stony surfaces often block or diminish mineral dust aerosol emissions through area fraction and roughness element effects. Incorporating these stone coverage effects is crucial for climate and environmental modeling research. Based on our field observations, this study combined the stone coverage effects into a dust simulation model for East Asia using two regression formulas and some constants. The double regression scheme assumed that the stone roughness density could be derived from the coarse fragment fraction of the SoilGrids 2.0 data set. According to the data set, the stone coverage is higher in Western Mongolia and Dzungaria and lower in the Chinese Gobi Desert and the Loess Plateau. Consequently, the model reproduced fewer dust aerosols in the higher coverage areas and more in the lower coverage areas. This simulation result was consistent with the World Meteorological Organization's current weather reports and satellite aerosol observations. The improved model reproduced the diversity of soil erodibility and was well balanced in performance statistics. This study is the first successful investigation of stone coverage effects on dust storm simulation using a realistic stone coverage map to the authors' best knowledge.
