Desert regions are characterized by complex terrain, frequent wind-sand activities, and extreme environmental conditions making vegetation recovery after disturbances difficult. The construction of large-scale photovoltaic (PV) power stations presents a significant challenge in balancing with vegetation protection. This study focused on a large PV site in the Hobq Desert examining the growth characteristics of at different positions within fixed PV arrays. It also analyzed changes in chlorophyll (Chl), soluble sugar (SS), soluble protein (SP), enzyme activity, and other physiological indicators to evaluate the plant's adaptive mechanisms to the presence of PV panels. The results showed that near the PV panels exhibited significant growth advantages, with plant height, leaf length, and stem-leaf nutrient content greater than the those of the control (CK) showing an adaptive trend of elongation, thinning, and enlargement. During the growing season, located before, behind, and under the panels increased Chl with environmental changes. The plants also adjusted their SS, SP, and other internal substance levels depending on their location relative to the panels. Notably, superoxide dismutase (SOD) and peroxidase (POD) activities were higher in all treated plants compared to those of CK, effectively removing O and providing HO protection, thereby delaying plant senescence and demonstrating strong adaptability. Through membership function analysis, the plant's tolerance levels at various positions around the PV panels ranked under panels > before panels > behind panels > CK. In conclusion, demonstrated adaptability to environmental changes at PV power stations by modifying its growth characteristics and physiological traits. These findings provide scientific evidence for the ecological industrial use of PV power stations in desert regions and offer practical guidance for vegetation restoration and ecological construction around such stations.
沙漠地区地形复杂,风沙活动频繁,环境条件极端,干扰后植被恢复困难。大规模光伏电站的建设在与植被保护平衡方面带来了重大挑战。本研究聚焦于毛乌素沙漠的一个大型光伏场地,研究固定光伏阵列内不同位置的[植物名称]生长特征。还分析了叶绿素(Chl)、可溶性糖(SS)、可溶性蛋白(SP)、酶活性等生理指标的变化,以评估植物对光伏板存在的适应机制。结果表明,靠近光伏板的[植物名称]表现出显著的生长优势,株高、叶长和茎叶养分含量均高于对照(CK),呈现出伸长、变细和增大的适应趋势。在生长季节,位于光伏板前、后和下方的[植物名称]随着环境变化叶绿素含量增加。植物还根据其相对于光伏板的位置调整其可溶性糖、可溶性蛋白和其他内部物质水平。值得注意的是,与CK相比,所有处理植物中的超氧化物歧化酶(SOD)和过氧化物酶(POD)活性更高,有效去除O并提供对H₂O₂的保护,从而延缓植物衰老并表现出很强的适应性。通过隶属函数分析,光伏板周围不同位置的植物耐受水平排序为下方>前方>后方>CK。总之,[植物名称]通过改变其生长特征和生理特性表现出对光伏电站环境变化的适应性。这些发现为沙漠地区光伏电站的生态产业利用提供了科学依据,并为这类电站周围的植被恢复和生态建设提供了实践指导。
