| 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750～770 nm光谱区内相关性较好,且在686 nm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。

| 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(R2=0.88), and then discuss the feasibility of exploring the rice chlorophyll concentration by way of hyperspectral remote sensing. |
