【摘要】 结合田间小区实验,获取了水稻生育期9组叶片叶绿素浓度和相应的光谱反射率数据,进行了相关分析研究,结果表明:水稻叶片叶绿素浓度与其光谱反射率之间具有相关性,在450～686nm和750～770nm光谱区内相关性较好,且在686nm处两者达到最高的相关性;水稻叶片的"红边"拐点波长位置与其叶绿素浓度之间具有很强的相关性,复相关系数为0.88,并由此进一步讨论了高光谱遥感定量探测水稻叶绿素浓度的可行性。更多还原

【Abstract】 By the field experiment,we achieve the chlorophyll concentration and reflectance of nine groups of rice leaves and investigate the quantitative relationships between them by correlation analysisThe results reveal that they have good relationship in the range of 450～686 nm and 750～770 nm, and the peak of the correlation is at the wavelength of 686nmMeanwhile, we find strong correlation between the wavelength of the Red edge inflection point and the chlorophyll concentration of the rice leaves(R\+2=088), and then discuss the feasibility of exploring the rice chlorophyll concentration by way of hyperspectral remote sensing.更多还原
