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.
