Abstract:: The photovoltaic power station in Mu Us Sandy Land was selected as the site. The vegetation growth condition, soil water content change and soil erosion and deposition depth variation outside the project area and under the solar panel were and observed to discuss the growth status of three plant measures and its ecological functions. The results were as follows. (1) Sedum aizoon L. grew better outside the project area, and Pennisetum alopecuroides (L.) Spreng. grew better under the solar panel. (2) The soil water content under the solar panel was lower than that of outside the project area in March and October. The soil water content under the solar panel was higher than that of outside the project area except Pennisetum alopecuroides (L.) Spreng. growing area in June. (3) The annual wind erosion of Sedum aizoon L. control effect was best outside the project area, and its soil erosion and deposition depth of one year were significantly lower than those in the other two vegetation growing areas (p < 0.05). The wind erosion control effect of Sedum aizoon L. was best in the vegetation dormant period and the wind erosion control effect of Pennisetum alopecuroides (L.) Spreng. was best in the vegetation growing period under the solar panel, but its soil erosion and deposition depth of one year under the solar panel were no significant difference (p > 0.05). It can be seen that we should plant Pennisetum alopecuroides (L.) Spreng. under the solar panel, and plant Sedum aizoon L. outside the station area.
