5. Conclusions SOC content, soil temperature, and soil moisture content were different at different slope positions. Soil temperature for 5 cm depth increased with altitude and soil moisture content for 5 cm depth declined with altitude. CO2 flux in eroded positions was greater than in depositional position in the initial 27 days after heavy rainfall events, but as the soil moisture content decreased with time, CO2 flux at depositional positions and eroded positions became nearly the same.In our study, of soil temperature and soil moisture content,changes in soil moisture content had the greatest contribution changes in CO2 flux in the initial 27 days where large changes in soil moisture occurred. However, as the soil moisture content decreased over time in the second measurement period, there was an apparent shift from moisture to temperature as the most important factor affecting the CO2 flux. The experimental results confirmed the original hypothesis that soil erosion affects CO2 flux via its effect on soil temperature and soil moisture at different slope positions.
