［Objective］ To explore the effects of different sand control measures on soil physicochemical properties and enzyme activity in sand blocking and stabilization zones, and their relationships, in order to provide technical support for measure selection and benefit evaluation. ［Methods］ Using mobile sand dunes and Haloxylon ammodendron(CK) as the control group, and ecological cushion sand barrier+Haloxylon ammodendron (ES), nylon mesh sand barrier+H. ammodendron (NS), woven bag sand barrier+H. ammodendron (WS), grass square grid sand barrier+H. ammodendron (GS), and clay sand barrier+H. ammodendron (CS) as the test groups, physical and chemical properties and enzyme activities of soil within 0~60 cm depth for six different sand control measures were analyzed. ［Results］ Compared with CK, there were significant changes in soil physicochemical properties and enzyme activities among the other five different sand control measures. 1) Within the depth range of 0~60 cm, there was no significant change in soil pH, but
