2017年8月东北地区土壤室内测量反射率数据集

在东北地区采集具有代表性的土样标本，在室内测量反射率，所有仪器为ASD Fieldspec 3和ASD Fieldspec 4 Hi-Res光谱仪（波长范围均为350nm-2500nm），土壤类别包括风沙土，白浆土，淋溶土，冲积土，黑土，沼泽土，棕壤，栗钙土，黑钙土，褐土，暗棕壤，潮土，草甸土，草甸盐土，水稻土，泥炭土，盐碱土等。数据内容包括光谱反射率、测量时间、经纬度、测量次数、测量人、预处理人、审核人。数据集共132条记录。

Representative soil samples were collected in Northeast China, and their reflectance was measured indoors. All measurements were conducted using ASD Fieldspec 3 and ASD Fieldspec 4 Hi-Res spectrometers, both with a wavelength range of 350 nm to 2500 nm. Soil categories included in this dataset are aeolian sandy soil, bleached albic soil, eluvial soil, alluvial soil, black soil, bog soil, brown earth, chestnut soil, chernozem, cinnamon soil, dark brown earth, fluvo-aquic soil, meadow soil, meadow salinized soil, paddy soil, peat soil, saline-alkali soil, and others. The dataset contains spectral reflectance, measurement time, longitude and latitude, number of measurements, operator, preprocessor, and reviewer. This dataset has a total of 132 records.
