Source of Sand for Aeolian Sand Migration

Aeolian sand migration is a complex natural phenomenon that affects the ecological environment and human activities in semi-arid regions worldwide. The availability of sand for aeolian sand migration is determined by multiple factors, including geology, climate, topography, vegetation, and human activities. These factors can affect the size, shape, and mineral composition of sand particles, which can influence their susceptibility to wind erosion and transport. Understanding the sources of sand for aeolian sand migration is essential for developing effective strategies for preventing or mitigating the negative impacts of aeolian sand migration. These strategies can include land management practices, such as soil conservation and vegetation restoration, as well as engineering interventions, such as sand barriers and windbreaks. By understanding the sources of sand for aeolian sand migration, we can work to protect the ecological environment and human activities in semi-arid regions and ensure their sustainable development.
