光伏电板对草甸草原植物功能群数量特征的影响

Effects of photovoltaic panels on quantitative characteristics of plant functional groups in meadow steppee

【目的】研究光伏电板对草甸草原植物功能群的影响。【方法】试验采用样方法对国家光伏、储能实证实验平台(大庆基地)草甸草原进行监测,测定了植物高度、盖度、多度、频度和地上生物量。【结果】光伏电板间多年生丛生禾草功能群和多年生根茎禾草功能群的高度、盖度、多度、频度和地上生物量相较于光伏电板下均有增加;莎草功能群光伏电板间的盖度、多度、频度和地上生物量均显著高于板下;对于多年生杂类草功能群和一、二年生植物功能群植物,光伏电板下的高度、盖度、多度和地上生物量均高于电板间。【结论】综合来看,光伏电板的架设会对草甸草原不同的植物功能群产生不同影响。

【Objective】The aim of the study was to investigate the influence of photovoltaic panels on plant func⁃tional groups in meadow steppe.【Method】Sample method was adopted to monitor meadow steppe of National pho⁃tovoltaic and energy storage Empirical Experimental platform(Daqing Base).Plant height,coverage,abundance,fre⁃quency and aboveground biomass were measured.【Result】The results showed that the height,coverage,abundance,frequency and above⁃ground biomass of the functional groups of perennial bunchgrasses and perennial rhizome grasses between the photovoltaic panels were increased compared with those under the photovoltaic panels.The interpanel coverage,abundance,frequency and above⁃ground biomass of sedge functional groups were significantly higher than those below the panel.The height,coverage,abundance and aboveground biomass of the perennial grass functional group and the biennial plant functional group were higher under the photovoltaic panel than between the panels.【Conclusion】In summary,the erection of photovoltaic panel have different effects on different plant functional groups in meadow grassland.
