Abstract Arid and semi‐arid lands are exceptionally sensitive to climate change. However, the application of phytolith analysis these environments is hindered by potential for lateral migration phytoliths during wind erosion, which may affect reliability phytolith‐based paleoenvironmental reconstructions. Moreover, there a lack quantitative studies dispersion deposition erosion. Here we apply Sutton's equation theoretical models from field blown sand physics engineering quantify various morphotypes in surface soil dunes Horqin Sandy Land China. Phytolith concentrations were determined addition sedimentary organic matter content grain size. Combined with plant communities, measurements used morphotypes, results compared models. We found that decreased exponentially under an annual average speed distance source; specifically, large proportion occurred within ~3–5 m. There significant linear correlations between concentration other environmental factors. A comprehensive form was estimate relatively (8.35%) short‐cell migrate laterally on vulnerable deposited almost situ, limited wind‐transported occurs overall. Our provide model practice template sediments, especially as proxy past vegetation ecological change Land, areas affected Additionally, palaeoenvironmental contexts satisfy criteria necessary investigate extent frequent aeolian activity.
