| 摘 要： | 应用地面高光谱仪测定古尔班通古特沙漠中梭梭和柽柳的冠层光谱,结合遥感影像分析比较了两种灌木树种的光谱响应曲线差异。结果表明:不论是沙土还是盐碱土,柽柳在近红外波段内反射率均高于梭梭,并根据这一规律性总结出了基于光谱特征的梭梭和柽柳的识别模型,最后对不同树种的光谱响应机制进行了探讨。 |
| 关 键 词： | 梭梭 柽柳 光谱特征 响应曲线 |

| Abstract: | Identification of tree species is importace in forestry investigation.Differences of spectral response curve between Haloxylon ammodendron and Tamarix spp.were investigated by combining ground spectral measurement with remote image analysis.The results showed that the reflectivity in near infrared of Tamarix spp.was higher than that of H.ammodendron both in sandlot or salina.The identification of the two species was established based on their spectral features.The mechanisms of spectrol response of differen... |
