主 题:Acid sulphate soil Hyperspectral sensing HyloggerTM Subsurface
摘 要:Acid sulphate soil(ASS) is a kind of soil which is harmful to the *** is hard to efficiently assess efficiently in the subsurface,although it is detectable on the surface by remote *** paper aims to explore a new way to rapidly assess ASS in the subsurface by introducing a proximal hyperspectral instrument,namely the HyloggerTMsystem which can rapidly scan soil cores and provide high resolution hyperspectral *** minerals in ASS,which usually act as indicators of the severity of ASS,such as iron oxides,hydroxides,and sulphates,as well as some clay minerals,such as kaolinite,have diagnostic spectral absorption features in the reflectance spectral range(400-2500 nm).Soil cores were collected from a study area and hyperspectral data were acquired by *** main minerals related to ASS were characterized spectrally,and were subsequently identified and mapped in the soil cores based on their reflectance spectral *** X-ray diffraction(XRD) and scanning electron microscope(SEM) were also applied to verify the results of the mineral *** main results of this study include the spectral characterisation of ASS and its main compositional minerals,as well as the distribution of these relevant minerals in different depth of cores.
