To understand the trend of the humidity evolution since 0.14Ma, the TOC and TOS have been determined and the pyrolysis of the organic matter is carried out by means of Rock-Eval for 235 samples (contained 113 loess and 122 paleosol samples)in 12.6m loess section of Weinan, Shanxi Province of China. The content of TOS is equal to or less than 0.008%, so it has not been discussed in this paper. The TOC content is 0.04%-0.64% in the section(0.04%-0.45% in the loess layer and 0.05%-0.64% in the paleosol layer). The TOC content is higher in paleosols than in the adjacent loess, especially in the intersurface between paleosol and loess layer. The main peak in Tmax frequency is distributed in 435-475℃ for paleosols and in 500-525℃ for loess. According to measurement results of a lot of nature and synthetic samples, the organic matter with Tmax of 435-450 is derived from bacteria or other lower organism and one with Tmax of 450-500℃ derived from higher plant or mixture of higher plant and lower organism, which is correlated to supergene water, including rain and other surface water and we called these pyrolysis hydrocarbon as pHC_(2-1) and pHC_(2-2) respectively. The organic matteer with Tmax of 500-600℃is mainly from inclusional organic matter in special secondary carbonate, which is correlated to evaporation and called as PHC_(2-3) The“specific humidity”concept from atmosphysics has been introduced, and the quaternary specific humidity fomula is that Q_q= (pHC_(2-1) +pHC_(2-2))/(pHC_(2-1)+PHC_(2-2) +PHC_(2-3)). According to the Q_qCalculation fomula, the variation of humidity is obtained, that is,60% in L2, 55%-75% in S_1,45%-61% in L_1 and 58%-73% in S_0 of the profile and now the evolution trend of the humidity is in more moist in loess area.
