摘　　要：本文综述了中国西北干旱区陆—气相互作用及其对气候影响研究的最近进展。文中不仅回顾了"中国西北干旱区陆—气相互作用观测试验"经过连续12年的观测和多次加强期观测所取得的干旱区陆面过程参数的分析以及边界层和陆—气相互作用特征等的分析和研究,而且综述了应用这些参数来优化有关陆面过程模式的参数化方案和改进有关陆面过程模式的研究;并且,本文还综述了关于中国西北干旱区感热输送特征以及西北干旱区陆—气相互作用对中国东部气候的影响及其机理,并揭示了中国西北干旱区春、夏季具有高感热输送特征,此高感热对中国东部夏季气候变异有重要影响。此外,本文还指出今后在此方面应进一步观测和深入研究的科学问题。We review the recent progress in studies of air-land interaction over the arid area of Northwest China and its impact on climate. The paper examines the analyses of the data observed continuously during the Field Experiment on Air-Land Interaction in the Arid Area of Northwest China （NWC-ALIEX） for 12 years and during many Intense Observation Periods of this project. The analyses of the land-surface parameters and studies of the characteristics of the boundary layer and air-land interaction in the arid area from continuous observations were reviewed as well as applications of these parameters to optimize the parameterization scheme in land surface models and to improve related land surface models. Moreover, we examined the characteristics of sensible heat transfer in the arid area of Northwest China and the impact of the air-land interaction in this area on climate variability in eastern China and its physical mechanism. We found a feature of high sensible heat transfer in spring and summer in the arid area of Northwest China, which has a strong impact on climate variability in eastern China. Finally, the issues that need further study and evaluation are also pointed out in this paper.
