【摘要】 为了探究风电场对草原植被的影响,进而影响土壤属性,本文以辉腾锡勒草原风电场为例,通过植被样地调查和土壤理化性质分析,研究风电场的建设对草原植被和土壤的影响。结果表明:风电场的建设降低了风电场内的植被生长各指标,相对于风电场外,风电场内的植被Patrick丰富度指数、Simpson优势度指数、Pielou均匀度指数、Shannon-Wiener多样性指数、地上生物量、植被株高均减少。相对于风电场外,风电场内土壤的有机质、碱解氮、速效磷、速效钾含量和电导率均减少。且风电场的建设对五花(杂草类)草甸的植被和土壤的上述消极影响比典型草原小。更多还原

【Abstract】 In order to explore the impact of wind farms on grassland vegetation,and thus affect soil properties,this paper takes the wind farm on the huitengxile prairie as an example and studies the influence of the construction and operation of the wind farm on the grassland vegetation and soil through the investigation of vegetation samples and the analysis of soil physical and chemical properties.The results show that:the construction of wind farms reduces the indicators of vegetation growth in wind farm interior.Compared with the outside wind farm,the vegetation Patrick richness index,Simpson dominance index,Pielou evenness index,Shannon-Wiener diversity index,aboveground biomass,and vegetation plant height in the wind farm interior are all reduced.And compared with the outside wind farm,soil organic matter,alkali nitrogen,available phosphorus,available potassium content and electrical conductivity in the wind farm interior are all reduced.Moreover,the negative effect of wind farm construction and operation on vegetation and soil of multifarious(weedy) meadows is smaller than that of typical grassland.更多还原
