摘　　要：荒漠光伏电站的建设通常会导致光伏面板下表层土壤温度降低1.5~4.1℃,土壤湿度增加3.8%~14.7%.站内土壤的pH、电导率、碱解氮、有效磷、速效钾、总氮、总磷等理化属性相较于站外土壤会出现下降、增加或不变的趋势,取决于光伏电站的位置和运营时间.光伏电站建成后,会通过直接或间接作用影响土壤微生物群落的结构和多样性,以及土壤生态环境功能的恢复.站内土壤相较于站外土壤的抗蚀性会增强,但强度取决于光伏面板阵列与风向的交会角.尽管光伏电站创造的低温条件有利于抑制板下土壤的呼吸,但土壤中的碳积累总量由土壤温度和湿度共同调节.光伏电站的建设会带来荒漠土壤的盐渍化、沙化和污染等次生环境问题.It was found that the construction of photovoltaic power stations in desert areas would significantly reduce the surface soil temperature under the plate by 1.5-4.1℃and increase soil moisture by 3.8%-14.7%.The physical and chemical properties of the soil in the station,such as pH,conductivity,available nitrogen,available phosphorus,available potassium,total nitrogen and total phosphorus,would decrease,increase or remain unchanged compared with the soil outside the station,depending on the location and operation time of the station.After a photovoltaic power station was completed,it would also affect the structure and diversity of soil microbial community through direct and indirect effects,affecting the restoration of soil ecological environment functions.Compared with the soil outside the station,the corrosion resistance of the soil inside it would be enhanced,but it depended on the intersection angle of the photovoltaic array and the wind direction.Although the low temperature conditions created by photovoltaic power stations seemed conducive to inhibiting soil respiration under the plate,the accumulation of total carbon in the soil should be regulated by soil temperature and humidity together.It should be noted that the construction of photovoltaic power stations would also bring secondary environmental problems such as salinization,desertification and pollution of desert soil.
