摘要：

草原地区大规模建设光伏电站会对当地自然环境造成影响，进而影响植物群落特征。本研究以土默特左旗羊草草原为对象，通过对光伏电板下各位置的植被进行调查取样，分析了物种多样性以及当地建群种羊草的生长状况。结果表明：（1）光伏电板下共发现7科13属14种植物，其中羊草广泛分布于光伏电板下方及周围各位置处。（2）光伏电板下物种Patrick丰富度指数、Shannon多样性指数、Pielou均匀度指数、Simpson优势度指数均表现为电板正下方显著高于电板前后檐。（3）电板下羊草的高度、盖度、密度和基径也均表现为电板正下方显著高于电板前后檐，对照组由南向北对应位置的相应指标均无较大变化。（4）电板正下方羊草的生物量显著高于电板前后檐，对照组由南向北的羊草生物量无显著差异。本研究可为草原地区光伏电站的生态恢复提供依据。

Abstract:

Large-scale construction of photovoltaic plants would affect environment and consequently plant community in steppe. In this study, we analyzed the effects of photovoltaic plants on species diversity and the growth status of Leymus chinensis in a steppe of Tumd Left Banner, through vegetation investigation and sampling at different locations under the photovoltaic panels. The results showed that: (1) A total of 14 plant species belonging to seven families and 13 genera were found under photovoltaic panels. L. chinensis was widely distributed at various locations under and around photovoltaic panels. (2) Patrick richness index, Shannon diversity index, Pielou evenness index and Simpson dominance index under the photovoltaic panels were significantly higher than those in the front and rear of the panels. (3) The height, coverage, density and basal stem diameter of L. chinensis under the panels were significantly higher than those in the front and rear of the panels. There was no significant difference in the corresponding indices from south to north in the control. (4) Biomass of L. chinensis under the panels was significantly higher than that in the front and rear of the panels. Moreover, there was no significant difference in the biomass of L. chinensis from south to north in the control group. Our results provide a scientific basis for ecological restoration of the photovoltaic plants in steppe areas.
