Abstract:: The soil physicochemical properties in the sites where were covered and uncovered (control) by moss crusts under Artemisia ordosica, Salix cheilophila Schneid and Pinus sylvestris Linn. var. mongolica Litv. at 0—2, 2—5, 5—10 cm depths were analyzed respectively. The effects of moss crusts on the soil physicochemical properties and its relationship between the type of vegetation were discussed. The results are as follows: (1) the moss crusts under three types of vegetation are able to significantly increase the soil stabilization，increase the proportion of fine sand (0.02～0.2 mm) and decrease the proportion (0.02～0.2 mm) of coarse sand; (2) the moss crusts under Artemisia ordosica and Salix cheilophila Schneid. can significantly increase the contents of soil organic matter, total N, available K and total P. Meanwhile, it’s able to decrease the contents of total K and available P in 0—2, 2—5, 5—10 cm depths, respectively. The effects of moss crusts under Pinus sylvestris Linn. var. mongolica Litv. at 0—2 cm depths were similar with those of Artemisia ordosica and Salix cheilophila Schneid. The difference is the moss crusts under Pinus sylvestris Linn. var. mongolica Litv. can significantly decrease the content of soil organic matter and have no significant effects on the contents of total N, total K, total P and available P at 2—5 cm and 5—10 cm depths; (3) in the process of ecology restoration in desert, the improvement of moss crusts on soil hysicochemical properties mainly focuses on the shallow layer and the improvement degree has close relations with the type of vegetation.
