摘要
本文研究了模拟酸雨对水稻叶片反射光谱特性的影响。结果表明：模拟酸雨会引起水稻叶片反射光谱的可见光区和中红外区的反射率升高，近红外区的反射率降低，相应的反射率比值也随之变化，一阶和二阶微分光谱蓝移，且上述变化的程度与酸雨的酸度、水稻的品种和生育期有关。这一结果也表明遥感技术监测酸雨污染作物是可行的。
The influences of simulated acid rain on the characteristics of reflectance spectra of rice leaves are described in this paper. The results show that acid rain could cause: increase of the reflectances in the visible and middle infrared waveband, decrease of the reflectances in the near infrared waveband, blue-shift of the first and second derivative spectra. There are relationships among the above changes and the pH-values of acid rain the vedeties and growth stages of rice. These results have proved it is possible to monitor the pollution of acid rain on crops using remote sensing.
