中文摘要作者运用100BXMTS野外光谱仪探测了小江支流蒋家沟新、老泥石流堆积物的光谱反射率,总结了新、老堆积物的反射光谱特征,进一步分析了影响泥石流堆积物反射光谱特性的因素(岩性、水分含量、植被覆盖),最后讨论了应用高空间分辨率遥感图像解译泥石流堆积物的可能性。
英文摘要 The authors detected the spect ral reflectance of debr is flow deposit by using field spectrometer 100BXMTS, made in U. S. , and sketches it s r eflect ance spect rum curve. Accoring to contrastive analyzing , the following conclusion are made:
( 1) The spectral reflectance of deposit relates to the deposit fo rmation time . The newer deposit is the higher reflectance,
the older depositis, the lower reflectance.
( 2) The spectral reflectance of deposit relates to the lit hological character of the solid particles in the deposit. Among the
deposits the a ut ho rs detected, the depo sit has the hig hest spectr al r eflectance, of which major solid ingredient is mylonit e,and the depo sit has the lowest spectr al reflectance, of which majo r so lid ing redient is metamor phics ever heavil metamorphosed.
( 3) The spectral reflectance of deposit relates to moistur econtent. The reflectance spectrum curve of the deposit with
the hig her mo istur e co ntent has obvious wave pattern, and the curve of the deposit with the lower moistur econtent has the flat one. With t he increm ent o f the deposit moistur econtent , the averager eflect anceappearsa trend of decrement -increment .
( 4) The spectral reflectance of deposit relates to the vegetation. The reflectance spectrum o f deposit with veg tation mainly reflects the spect rum of plant.
