Résumé partiel
Badan Jilin desert has poor climate conditions,few rainfall,strong evaporation,less vegetation coverage and extremely fragile ecological environment.Therefore,it is of great significance to study the water migration in the gas bearing zone of Badan Jilin desert and reveal the mechanism of water migration in the gas bearing zone for exploring the source of groundwater in Badan Jilin desert and improving the local ecological environment.Based on the data of field experiment,the paper studies the water migration law of the gas-bearing zone in Badan Lake area of Badan Lake Desert in Badan Jilin desert by analyzing the data and combining with numerical simulation.In this paper,the desert vadose zone is studied by in-situ test,indoor test and numerical simulation.The influence of different groundwater level buried depth on water migration in the gas bearing zone is analyzed.The relationship between temperature and water migration law in the vadose zone is studied.The coupled model of water vapor and heat in the desert gas belt is constructed to reveal the law of infiltration and evaporation of atmospheric precipitation in desert area,which provides the basis for the evaluation of groundwater resources in desert area
