Abstract: Phosphorus (P) is one of limiting nutrient elements in sandy land ecosystems of arid and semiarid areas, and the soil P cycling on sandy lands is of  great significance in maintaining  ecosystem productivity of sandy land, being paid more and more attention by the people. In this paper, the latest research advances at home and abroad on the sandy land soil P sources, P pools, and P cycling pathways, and the factors affecting the P cycling were summarized, with the following further research aspects suggested: 1) the action mechanisms of the factors affecting the P cycling, 2) the P budget fluxes in different P cycling pathways, and 3) the status of soil P balance and the sustainability of soil productivity under different land use. The above research aspects would give references to the maintenance of sandy land ecosystem productivity and the mitigation of the contradictions between human beings and natural resources and environment.
