摘　　要：青藏高原中部地区地面蒸发过程主要发生于５－１０月，７月蒸发最为剧烈。与其它因子相比较，地面蒸发量与水面蒸发量相关关系最好，与潜在蒸发量相关关系次之。下垫面条件对地面蒸发量影响很大，冻结与非冻结地表面蒸发量可相差２－３倍。与更为干旱的高原西部的天山地区的研究成果相比，该区衡量蒸发能力的指标和实际蒸发量均要高出许多。In centre of the Tibetan Plateau, the process of evaporation mainly occures during theperiod from May to October, and peaks in July. It is well influenced by frozen degree ofground surface. We also found that the soil evaporation is closely linked to the water evapo-ration. And the largest amount of possible evaporation and real evaporation over the TibetanPlateau is the most striking feature in comparison with that in Tianshan areas.
