Effects of photovoltaic power plant construction on vegetation communities in typical habitats in the cen-tral arid zone of Ningxia
摘要
Abstract
[Objective]Explore the impact of photovoltaic power station construction on vegetation communities in typical habitats in the central arid zone of Ningxia.[Method]This study took four photovoltaic power stations(Huarun,Huqin,Guangyuan,and Guonei)in the arid belt of central Ningxia,as the research objects,investigating the vegetation community structure and diversity characteristics in different locations(including the area under photovol-taic panels(BX),the area between photovoltaic panels(BJ),and the grassland outside the fence of the power station(CK)).The chemical properties of soil were measured in different locations.[Result]1)In the four power stations,the plant cover in the BJ area was 1.30～1.50 times higher than that in CK,and the biomass was 1.21～2.60 times higher than that in CK.Meanwhile,the soil organic matter,available potassium,and pH value were 1.95～3.39 times,0.4～1.64 times,and 0.57～0.78 times higher than that in CK,respectively.In all power stations,the plant height was highest in the BX areas.2)The vegetation heterogeneity in the power stations was enhanced,accompa-nied by significant shifts in plant life forms.Among them,the importance value of perennial plants was highest in BX area,followed by BJ,and lowest in CK.The dominant plant species in the BJ area were displaced to a certain ex-tent.3)The Shannon-Wiener index and species number in all power stations were highest in BJ,but the Simpson in-dex and evenness index did not show significant differences among different locations.(4)Correlation analysis showed that soil nutrients were positively correlated with vegetation community quantitative characteristics and diver-sity indices(P<0.05),while soil organic carbon,available potassium,and conductivity were negatively correlated with species number(P<0.05).[Conclusion]To sum up,the construction of photovoltaic panels has improved the structure of the grassland vegetation community and enhanced its productivity in the arid belt to a certain extent.How-ever,the base landscape is constantly fragmented and the patch shapes have become irregular,which has also led to an increase in vegetation heterogeneity.关键词
