摘要
Based on the measurement and analysis of the carbonate contents,chloride ion contents and sulfate radical contents of the Miocene sediment in the Honggouzi section of the western Qaidam Basin, the climate changes in this area can be divided into the following four stages. The erosion rate of this area shows no obvious connection with climate,but is well consistent with tectonic activities,namely,the tectonic active period corresponds with the stages of the high erosion rate or the erosion rate increases dramatically. Thus, in Honggouzi area, the regional tectonic activity is the main factor to control the erosion rate.
