【摘要】 作物反射光谱特性是利用遥感信息进行生态监测的基础资料。为此,我们应用302型野外分光光度计对水稻反射光谱进行了测定。分析结果表明,水稻和主要旱田作物(如谷子、大豆等)的反射光谱虽然具有共同的特征,但由于种类不同,生态条件不同,其反射光谱仍存在差异。水稻在不同物侯期,不同生育状况条件下其反射光谱也有差异。均以近红外波段差异最显著,为图象解译提供了依据。更多还原

【Abstract】 The reflective spectral characteristics of crop lands are essential infor mations to monitor the ecological change for remote sensing. Reflective spectra of rice fields were determined with an outdoor spectrophotometer (Type 302) .These spectra are different from those ofotner lands of crops such as millet, soybean. And the spectra of the same rice field in growthstages are also different. The spectral variations are appeared near infrared band, which are Important informations for translating the images. (L)更多还原
