摘　　要：为了解酸雨污染对草坪草生长的影响,以高羊茅和多年生黑麦草为材料,通过盆栽试验,研究不同pH酸雨条件下对草坪草生长和代谢的影响。分别测定生物量、叶绿素含量、超氧化物歧化酶、过氧化物酶、丙二醛和电导率等指标。结果表明,高羊茅和多年生黑麦草鲜重、叶绿素含量等在高酸度、长时间胁迫下整体呈降低趋势,氧化物歧化酶、过氧化物酶则先高后低,丙二醛和电导率则随酸雨pH减小而有增加趋势。For the sake of understanding acid rain influence of the pollution upon the turfgrass growth,With the material of Fescue arundinacea and Lolium perenne,this paper studied on the physiological characteristics of turf grass under different pH values of simulated acid rain.It measured indicators like fresh weight,chlorophyll content,SOD,POD,MDA and electric conductivity.The result indicated that,under conditions of high acidity and long period of time,the fresh weight of Fescue arundinacea and Lolium perenne,and chlorophyll content entirely showed a reduced trend,while the contents of SOD and POD first rose and then fell down.The pH value of acid rain decreased,there was an increasing trend of MDA and electric conductivity.
