英文摘要	Based on observational data of arid, semi-arid and semi-humid areas in Northwest China, the characteristics of surface-water heat transfer and land-surface parameters were compared and analyzed. The results show that the annual mean net radiation was largest in the semi-humid area, followed by the semi-arid area, and then the arid area: 77.72 W/m(2), 67.73 W/m(2), and 55.47 W/m(2), respectively. The annual mean sensible beat flux was largest in the arid area, followed by the semi-arid and semi-humid areas, while latent heat flux showed the reverse. The annual mean sensible heat flux in arid, semi-arid, and semi-humid areas was 85.7 W/m(2), 37.59 W/m(2), and 27.55 W/m(2), respectively. The annual mean latent heat flux was 0 W/m(2), 26.08 W/m(2), and 51.19 W/m(2), respectively. The annual mean soil-heat flux at the 5-cm soil layer in arid, semi-arid, and semi-humid areas was 1.00 W/m(2), 0.82 W/m(2), and -1.25 W/m(2), respectively. The annual mean surface albedo was largest in the arid area, followed by the semi-humid area; and the smallest was in the semi-arid area: 0.24, 0.21, and 0.18, respectively. The annual mean Bowen ratio in the semi-arid area was about 2.06, and that in semi-humid area was about -0.03. The annual mean soil thermal conductivity in the arid, semi-arid, and semi-humid areas was 0.26 W/(m.k), 1.15 W/(m.k), and 1.20 W/(m.k), respectively.
