Measurement of condensation water was carried out on five different underlying surfaces around an artificial oasis in the arid region of China,from July to October in 2004.In this paper,not only the formation process of condensation is analyzed in detail,but also the main effect factors concerning the amount of condensation water are discussed.The results indicate that hygroscopic condensation is the dominate one in the desert oasis,which begins at 16:00~18:00 and ends at 7:00~8:00.Sand water content is the key factor determining whether condensation occurs,but the process of condensation is controlled chiefly by relative humidity and air temperature.Moreover,the daily range of temperature can also affect the condensation amount partly.In the artificial forest,artificial grassland,plain sand without vegetation,up-dune and inter-dune,the monthly mean condensation water is 5.1 mm,4.0 mm,3.1 mm,1.8 mm and 1.0 mm,respectively.
