中文摘要	【目的】探究光伏电站环境内不同植被恢复措施下0~40 cm土壤有机碳质量分数和储量的变化特征,为干旱区光伏电站生态治理模式优化配置提供理论依据。【方法】在光伏电站内选取3种人工建植植被样地:樟子松Pinus sylvestris var. mongolica、黄芪Astragalus membranaceus var. mongholicus、苜蓿Medicago sativa,以未受电站建设干扰的天然植被样地作为对照。【结果】重新建植植被后,樟子松、黄芪和苜蓿样地的土壤有机碳质量分数和储量仍然显著低于对照(P<0.05),但在这3种植被中,樟子松样地的土壤有机碳质量分数相对于另外2种样地显著增加了4.99和6.80 g·kg~(-1),而有机碳储量则显著提高了14.52和19.37 t·hm~(-2)(P<0.05)。研究区土壤有机碳质量分数和储量整体上随土壤深度增加而显著降低(P<0.05)。植被类型和土壤深度及其交互作用显著影响研究区的土壤有机碳质量分数。此外,土壤pH和电导率也是影响土壤有机碳质量分数和储量的重要指标。【结论】随着电站内环境治理工作的推进,相比于草本植被,光伏电站内可以通过人工种植樟子松来提高土壤固碳作用,并尽量减少后期的人为干扰。
英文摘要	[Objective] This study aims to explore the change characteristics of soil organic carbon mass fraction and storage at 0-40 cm under different vegetation restoration measures in the environment of photovoltaic power station, so as to provide theoretical basis for the optimal allocation of ecological management mode of photovoltaic power station in arid area. [Method] Three artificial vegetation plots(Pinus sylvestris var. mongolica, Astragalus membranaceus var. mongholicus, Medicago sativa) in the photovoltaic power station were selected as the research objects, and the natural vegetation plots undisturbed by power station construction were used as the control. [Result] After replanting, the soil organic carbon mass fraction and storage of P. sylvestris var. mongolica, A. membranaceus var. mongholicus and M. sativa were still significantly lower than those of the control (P<0.05). However, compared with the other two plots, the soil organic carbon mass fraction of P. sylvestris var. mongolica sample plot increased significantly by 4.99 and 6.80 g·kg~(-1), while the organic carbon storage increased significantly by 14.52 and 19.37 t·hm~(-2) (P<0.05). The mass fraction and storage of soil organic carbon in the study area decreased significantly with the increase of soil depth (P<0.05). Vegetation type, soil depth and their interaction significantly affected the organic carbon mass fraction in the study area. In addition, soil pH and electrical conductivity were also important indicators affecting the mass fraction and storage of organic carbon. [Conclusion] With the advancement of environmental governance in the power station, compared with herbages, P. sylvestris var. mongolicacan can be artificially planted in the photovoltaic power station to improve soil carbon sequestration and minimize human interference in the later stage, which is of great significance to improve regional ecological benefits.
