AQUATIC VEGETATION CANOPY SPECTRAL CHARACTERISTICS UNDER DIFFERENT COVERAGE PERCENTAGES
Abstract
The Japanese roof iris, Iris tectorum Maxim., is used as the research object, and we analyze the spectral characteristics of the aquatic vegetation in outdoor mesocosms under different coverage percentages. A field spectrometer was used to measure the irises’ vegetation canopy spectral reflectance. Experimental results showed that decreases in the iris coverage led to corresponding decreases in the canopy spectral reflectance. Differences in the iris canopy spectral reflectance under different coverage percentages were most pronounced in the 740-1350 and 1450-1800 nm band ranges. Linear relation models were constructed for the coverage and reflectance data at selected wavelengths, and high correlation coefficients were obtained. The results of the study are intended to provide model support for the monitoring of wetland aquatic vegetation using spectroscopy and are combine with remote sensing technology to aid in image interpretation and classification.
