[Objective] The variation of temperature and water content in a quicksand surface layer under different protective measures and their influencing mechanisms were investigated in order to provide a theoretical basis for vegetation restoration in a desert area. [Methods] Field tests were carried out to examine five protective measures (single pipe protection, pipe coated with reflective film, pipe wall opening, pipe covered with straw, and double-pipe protection), three pipe diameters (75, 90, 110 mm), and three open field heights (10, 15, 20 cm). The unprotected quicksand surface was used as the control. The diurnal variation characteristics of surface soil temperature and water content were measured using a soil temperature and water content recorder in the quicksand surface layer. [Results] The five protective measures contributed significantly to the cooling effect, with double-tube protection showing the best cooling effect. Under the same protective measures, the surface layer temperature of the pipe inte
