摘要：

Soil quality in alpine ecosystems requires regular monitoring to assess its dynamics under changes in climate and land use. Visible near-infrared (vis-NIR) spectroscopy could offer an option, as sampling and transporting large numbers of soil samples in the Qinghai-Tibet Plateau is extremely difficult. However, the potential for in situ vis-NIR spectra and the optimal algorithms need to be defined in this region. We have therefore evaluated the performance of a deep learning method, multilayer perceptron (MLP), for in situ spectral measurement ...
