摘要
Based on airproof plastic greenhouse which built on the top of Mogao Grottoes and was used to monitor condensation water and air temperature and humidity, the moisture interaction between soil and atmosphere under the condition of classic extreme dry climate in extreme dry area was discussed. The measuring result of condensation water and air temperature and humidity in greenhouse showed that the groundwater was transferred to atmosphere under the influence of thermal power, and the main reason was the alternation of decomposition of bound water and adsorption of soil salinity under the action of temperature. The study on moisture interaction between soil and atmosphere in extreme dry area could provide some references for the protection of rare cultural relics in Mogao Grottoes.
