Abstract
Arsenic produce toxic effects to plants,animals and the human body produce,so monitoring crop arsenic pollution is necessary. Through the study on arsenic contamination of rice spectral differences,by using the singular spectrum range,singular amplitude and singular index parameters such as the singularity of the rice,it showed that,in the early growth stage of rice,a small value in the 350~680 nm wavelength spectral was different,which changed in the range between 3.67%and 7.86%,and in the rice heading stage,the change range was between 7.83%and 16.19%,only weak information extraction of arsenic contaminated rice lagged behind the original use of measured spectra.Arsenic contamination of rice spectrum singular scope mainly concentrated in the 500~850 nm,singularity amplitude reached the maximum at the heading stage,and the singular index according to the rice growth period increased gradually.The singular spectrum could effectively monitor arsenic pollution in rice stress.关键词
