Abstract

Biological Soil Crusts (BSCs) are a critical part of the surface landscape in desert ecosystem, and play a key role in the recovery of desertified land and the fixation moving-dune. The physicochemical properties of BSCs and their respective subsoils in the revegetation area of the southeast margin in the Tengger desert were investigated, and the effects of BSCs on subsoil were analyzed. The results indicated that:the thickness, porosity, silt and clay content, field water holding capacity and the concentrations of organic carbon, inorganic carbon, total nitrogen, available nitrogen, available phosphorus, available potassium and electronic conductivity of crusts layer were moss crust > mixed crust > lichen crust > algae crust, while sand content and bulk density were moss crust < mixed crust < lichen crust < algae crust. The physicochemical properties of the 0-2 cm and 2-5 cm soil layers below crusts showed the same patterns. In general, the effects of moss crust and mixed crusts on their subsoil were greater than those of lichens and algae crusts; the influence of crusts on subsoils decreased with the increase of soil depth. Our results suggest that the colonization and development of BSCs are the key factors thataffect soil formation and soil quality in desert ecosystem.

Key words： biological soil crusts; topsoils; physicochemical properties; sand fixation vegetation area; Tengger Desert
