Abstract:
Hyper-spectral technology is a revolution in remote sensing. Now hyper-spectral technology is being used well in vegetation remote sensing. Hyper-spectral characteristics of vegetation and the analysis methods are discussed. This paper emphasizes the spectrum responses of changed plant chlorophyll content caused by nutrient stresses, indicates the application dominance of vegetation indexes and derivative spectrum to extract vegetation information. The situation of internal heavy metal pollution, especially plumbum, in the soil and the mechanism of heavy metals' effect on plants are summed up. Based on the hyper-spectral characteristics of polluted vegetation brought by heavy metals in the soil, this paper puts forward that the ground hyper-spectral remote sensing can be used as a method of new style to monitor the pollution situation of heavy metals in the soil. Finally the current situation, as well as the prospects of its application in supporting and verifying hyper-spectral data upper air, is discussed.
Keywords:vegetation  hyper-spectrum  remote sensing  plumbum pollution  monitoring
