摘　　要：以山西北部某一风电场为研究对象,利用施工前、施工完毕以及植被恢复三年后3个时期的遥感影像,解译土地利用类型,同时借助与对照区的植被覆盖度变化率分析风电场建设对生态环境的影响。分析发现风电场建设改变了原有草灌生态系统的结构,加大了风场范围内生境破碎化程度;风电场的建设对草灌生态系统的影响范围达到两侧100 m范围。随着施工结束后采取植被恢复措施,项目周边生态环境得到不同程度的恢复,说明植被恢复对受影响区域有一定的补偿作用。Taking a wind farm in the north of Shanxi Province as the research object,the land use types were interpreted by using the remote sensing images of three periods:before construction,after construction and three years after vegetation restoration.Using change rate of vegetation coverage in comparison with control area,the influence scope and characteristics of wind farm construction on ecological environment are analyzed.The results show that the construction of wind farm directly changes the structure of the original grass shrub ecosystem,and increases the degree of habitat fragmentation.The impact of the construction of wind farm on the grass irrigation ecosystem can reach 100 m on both sides.With the vegetation restoration measures taken after the construction,the ecological environment around the project has been restored,indicating that the vegetation restoration has a certain compensation effect on the affected area.
