中文摘要	利用中国科学院寒区旱区环境与工程研究所那曲高寒气候环境观测研究站2007年7-8月的观测数据，同时借助于中尺度模式WRF模拟了藏北地区的地表通量，并通过4组敏感性试验（即改变土壤湿度和植被覆盖度）分析了该地区辐射收支和热量交换特征。结果表明, WRF模式能较好地再现青藏高原复杂下垫面的地表热通量日变化特征。当模式初始场的土壤湿度和植被覆盖度增大到与观测事实一致时，得到的模式模拟结果较好, 尤其是感热, 潜热通量变化的模拟结果与观测值接近。
英文摘要	Based on the observation data from July to August in 2007 derived from Nagqu station of Plateau Climate and Environment, Cold and Arid Regions Environmental and Engineering Research Institute and WRF model, the characteristics of land surface heat flux, land surface radiation and energy flux exchange were analyzed in the northern Qinghai-Xizang Plateau. The four groups of sensitive experiments which changed soil moisture and vegetation coverage in initial model input field were designed. The simulated radiation and energy exchange analyzed in the north Qinghai-Xizang Plateau. WRF model can reappear the daily variation of land surface fluxes in the Qinghai-Xizang Plateau. When the initial values of soil moisture and vegetation coverage were changed to close to in-situ data, the modeling results show good outcome. Although WRF model can simulate well land surface heat fluxes in the Qinghai-Xizang Plateau, but it still exist error and shortage for land surface heat fluxes. All of these facts which land surface heat fluxes were changed clearly will provide strong evidence for the study of energy and water cycle in the Qinghai-Xizang Plateau. It is the most obvious that the simulated results of changes of sensible and latent heat fluxes, are very closed to the observation data.
