Abstract Based on the last 30 years’ research on the relationship between the susceptibility of loess-paleosol and climate, we tend to believe that the enhancement of paleosols susceptibility mainly results from the ultrafine grains of magnetite and maghemite developed by biological and chemical weathering during the course of pedogenesis. Moreover, susceptibility is influenced by other factors, such as: the background value of loess-paleosol’s susceptibility, eluviation, the magnetic minerals’ aging delayed by organic matter and its own susceptibility. Consequently, the susceptibility of loess-paleosol is influenced by multi-factors, mainly by climatic conditions.
