摘　　要：以菜豆为试材,采用无土栽培浇灌不同配方营养液的方法,研究了不同重金属胁迫对植物叶片功能性状和高光谱指数的影响,以期为植物重金属胁迫的快速监测提供参考依据。结果表明:重金属胁迫对菜豆叶片功能性状指标和高光谱指数的影响程度不同。重金属胁迫显著影响叶片功能性状指标和叶绿素、胡萝卜素相关的高光谱指数,对花青素、水分相关的高光谱指数没有显著影响。锌、铜和镉对叶片功能性状和高光谱指数诸多指标均造成了显著影响,铅和镍主要影响高光谱指数,而铬则主要影响叶片功能性状指标。Taking Phaseolus vulgaris Linn.as test material,adopting the method of soil-free cultivation with different nutrient solution treatments,the effects of different heavy metal stresses on leaf functional traits and hyperspectral index were investigated,in order to provide reference for the rapid monitoring of heavy metal stresses in plants.The results showed that heavy metal stresses had different degrees of effects on the functional trait metrics and hyperspectral index of P.vulgaris leaves.Heavy metal stresses significantly affected leaf functional trait metrics and chlorophyll-related,carotene-related hyperspectral index,but had no significant effects on anthocyanin-related and water-related hyperspectral index.Zn,Cu and Cd caused significant effects on both leaf functional trait metrics and hyperspectral index,while Pb and Ni mainly affected hyperspectral index,and Cr mainly affected functional trait metrics.
