摘要
Soluble salts on the surface ground in Guliya ice cap area change with climatic factors, especially with dry and wet conditions. pH and electric conductivity values of the Guliya ice core depend on soluble salts originated from surrounding arid or semi-arid regions, therefore the dry and wet changes can be approached by them. Results show that the approached dry and wet changes since the little ice age are consistent with that deduced from δ18O and accumulation rate.
