Blue clayey paddy (BP) soil and red paddy soil (RP) were selected as a case study of differences in hyper-spectral and soil organic matter (SOM) spectral-parameter-models of paddy soils derived from different parent material.The results show that the reflectance of BP derived from the sediments is higher than that of RP derived from the Quaternary red earth within the studied bands as a whole, and the absorption characteristics of RP is more evident than that of BP within the absorption bands related to iron oxide.The variation of the first derivatives of reflectance of responsibility, on the whole, also tends to be more vigorous than that of BP, and it is more significant at the bands related to iron oxide and 2 200 nm especially.The number and wavelength of bands included in SOM content spectral-parameter-models differ drastically between BP and RP.The SOM content spectral-parameter-models of the paddy soils are shown to have unique characteristics related to the parent materials.
