摘　　要：地处高原平台的若尔盖地区下垫面的变化影响地气界面的热质传递。多种数据表明,若尔盖高原的水汽输送情况直接影响中国北部地区的干旱情况。本文采用多种蒸发公式计算若尔盖不同下垫面蒸发量的差异,分析了若尔盖高原盆地中下垫面的状况对蒸发量的影响,讨论了不同下垫面对若尔盖地区水汽输送、土壤沙化退化影响机制。The changes of underlying surfaces in Zoige Plateau Basin influenced heat and moisture transmission between Ground and Air surfaces. Many kinds of data indicated that the drought in northern China arid zones was directly influenced by the water vapor transmission in Zoige Plateau Basin. This research utilized a variety of evaporation formula to calculate the evaporation differences in Zoige Plateau Basin and investigated the influence of the state of Zoige Plateau Basin on evaporation. It also gives advanced and feasible advices on dealing with water vapor transfer and desertification in Zoige by focusing on different underlying surfaces.
