- 摘要:
- 为了探究光伏电站建设对植被、土壤的影响，通过样地调查和试验分析对靖边县光伏电站内光伏板未遮阴（NS）、遮阴（S）及电站周边区域（SA）的土壤理化性质、植被种类、α物种多样性和地上生物量进行了分析比较。结果表明：相对于SA，光伏电站内（NS，S）土壤含水量、有机质、速效磷、速效钾、植物种类、物种Patrick丰富度指数、Shannon-Wiener多样性指数、Pielou均匀度指数、Simpson优势度指数、地上生物量鲜重和干重均增加，土壤pH和电导率降低，S区域容重增加，NS降低；电站内相对于S区域，NS的土壤含水量、pH、电导率、养分、α物种多样性和地上生物量均增加，容重降低。综合来看，在干旱半干旱区域，光伏电站建设对土壤、植被生态系统的促进作用优于所带来的负面影响。
- Abstract:
- Based on experiment conducted in the sites unprocessed(NS), shaded by solar panels(S) and the surrounding(SA) in photovoltaic power in Jingbian County, soil physicochemical properties, plant species, α species diversity and aboveground biomass were analyzed and compared through investigation of sample plot and experimental analysis to explore the impact of photovoltaic power construction on vegetation and soil. The results shows that the soil moisture contents, organic matter, available phosphorus and potassium, plant species, α species diversity and fresh and dry weight of aboveground biomass in the area of photovoltaic power plant construction increased and soil pH and electrical conductivity were lower compared with those in the area of SA. Soil bulk density in S increased, soil bulk densities were lower in NS and SA. The soil moisture, pH, nutrient, α species diversity and aboveground biomass increased, and soil bulk density was lower in NS compared with these in S of photovoltaic power plant construction. According to the above results, in arid and semi-arid regions, the positive impact of photovoltaic power construction on soil and vegetation ecosystem outweighs the negative impact.
