From September in 2013 to September in 2014, the temperature of brown soil in 0–100 cm (interval 10 cm) layer was measured in situ. Besides, fresh soil samples were collected in 0–100 cm (interval 10 cm) layer from a brown soil profile using soil drilling and then soil Eh, pH and moisture were measured. The results showed that: 1) From September in 2013 to November in 2013, soil Eh were stable in the range of 300–400 mV. But the soil Eh increased significantly and then decreased during freeze-thaw period from December to March in next year. During the alternation period of wetting and drying from April to June, soil Eh was in a fluctuating trend. Different from other years, there is little rainfall from July to August in 2014. Then Eh increased with the decrease of rainfall, but decreased with the increase in soil depth. In addition, surface soil Eh is smaller amplitude due to more organic matter. 2) From September to November in 2013 and from April to August in 2014, soil moisture content was negatively correlated with Eh (P<0.05). From December in 2013 to March in 2004, soil moisture was positively correlated with Eh significantly (P<0.05). 3) During freeze-thaw period, the soil pH was positively correlated with Eh significantly (P<0.05).
