摘要：为了研究光伏电厂对高寒荒漠草原区植被与土壤的影响,以共和盆地塔拉滩倍翔光伏产业园区为研究对象,采用样地调查法选取围封区(WF)、围封+光伏区(WG)和自然生长区(DZ)内3块10m×10m典型样地,调查了各类型区植被群落结构和土壤理化性状特征,并结合各指标间的差异评价了光伏电厂对其植被和土壤的作用效果。结果表明:围封和光伏电厂对植被与土壤具有显著影响,与2013年相比,2015年围封+光伏区(WG)植被群落的植物种数、盖度、地上生物量、丰富度指数、土壤含水量、有机质和全氮依次升高了116.7%,83.9%,68.7%,119.2%,88.6%,83.0%和81.8%,呈现显著变化(P<0.05)。光伏发电板可改善高寒荒漠草原植物生长所需的环境因子,增加土壤水分,起到保育脆弱生态系统和防风固沙的作用,促使荒漠草原朝着正向演替发展。
In order to find out the impact of the construction of photovoltaic power plants on vegetation and soil in alpine desert steppe,this study selected the Beixiang photovoltaic industry park of Tara Beach in Gonghe Basin as the research object,and conducted consecutive monitoring plots in August of 2013—2015.By choosing 3typical plots of 10m×10mwithin fenced area,PV＋fenced area and natural growth zone,and through using quadrats,this study surveyed vegetation structure characteristics and analyzed soil properties in laboratory.Finally,different indicators that evaluated the effects of photovoltaic plant were combined.The results showed that：Fenced and photovoltaic plants had a significant impacts on the vegetation and soils.Compared with the data which surveyed in 2013,the photovoltaic fenced area data of plant species numbers,vegetation coverage,aboveground biomass,richness index,soils water content,organic matter content and nitrogen content respectively increased by 116.7%,83.9%,68.7%,119.2%,88.6%,83.0%and 81.8%in 2015,which showed significant change（P〈0.05）.Voltaic panels improved environmental factors of plant growth in alpine desert steppe,especially increased soil water content,which could protect fragile ecosystems and showed sand-fixing effect,promoting the succession development of desert grassland.
