| 摘 要： | 介绍了健康植物光谱特征及各波段反射率的影响因子,以及植物受到污染胁迫后其光谱特征的变化情况,如可见光、近红外波段光谱反射率升高或降低,红边漂移等,同时指出污染物质主要通过改变植物叶片的色素含量而对植物光谱产生影响。阐述了污染植物光谱信息提取方法,及植物光谱效应在环境污染遥感监测中的应用情况,提出了今后高光谱遥感在植物监测应用方面需要进一步解决的问题。

| Abstract: | Spectral characteristics on healthy vegetation and influence factor on spectral reflectivity at all bands were discussed as well as the change of spectral characteristics on contaminated vegetation including spectral reflectivity at visible light and near infrared band altered and red edge shifted. Results showed that contamination mainly affect vegetable spectrum through altering pigment contents of leaves. The drawing method of vegetation pollution information and application of vegetation spectral characteristics to remote sensing in environment pollution monitoring were described in details, and application of hyperspectral remote sensing in vegetation pollution monitoring need further study. |
