Floating dust is one of the weather phenomena, a kind of air compositions with stable chemical property, and provides a good object for researching the regional and global ari movement and environment change. It, however, results in the climatic effects and deterioration of natural environment, and has been a serious atmospheric and environmental problem. It is of significance to research the properties, composition, sources and movement routes of floating dust as well as its impacts on the geochemical circle of the elements in biosphere, Quaternary terrigenous sediment and air pollution. Based on lots of references, this paper sums up the main achievements and progresses in the research on floating dust at home and abroad since recent 20years, which mainly include 7 aspects: a. The characteristics, classification, monitoring, prediction and impacts of floating dust; b. The temporal and spatial distribution characteristics and change laws of floating dust; c. The formation causes of dust fall and climatic features; d. The sources and transport of floating dust; e. The physical and chemical properties of floating dust; f. Floating dust and loess; and g. Floating dust and soil.
