使用遥感数据制作土壤图时,作物的反射在提取土壤信息中起对立的干扰作用。本文就作物给土壤的反射特性带来的影响,建立了简单的光学模型,并由此提出了与作物反射无关的能提取土壤信息的土壤指标数(Soil Index)。为了进一步研究土壤指标数的可靠性,与适合于提取作物信息的其它频
When producing soil maps using remote sensing data, crop reflections play an opposite role in the extraction of soil information. In this paper, we have established a simple optical model of the effects of crops on soil reflectance, and proposed a Soil Index that can extract soil information unrelated to crop reflectivity. In order to further study the reliability of soil index, and other suitable for extracting crop information of the frequency
