【摘要】 干旱区陆面过程和大气边界层不仅与气候、生态、水资源密切相关,而且影响我国气候格局和东亚大气环流,是一个十分重要的研究领域,近20多年已取得了比较系统的研究进展。从干旱区陆面热力和水分过程特征、干旱区大气边界层结构特征、干旱区陆面过程参数及其参数化公式、非均匀下垫面大气边界层理论、干旱城市大气边界层特征与污染机理等方面归纳总结了干旱区陆面过程和大气边界层领域取得的部分研究进展。并且,认为科学试验的代表性、复杂下垫面的影响、尺度转化、地表能量不平衡、极端天气过程的相互作用、水分过程的复杂性等问题是干旱区陆面过程和大气边界层研究领域的突出问题和未来研究重点。更多还原

【Abstract】 Land surface processes and atmospheric boundary layer in arid regions in China as a key physical process are not only closely related with the regional climate,ecology,water resource,but also have impact on the pattern of China climate and Eastern-Asian atmospheric circulation.In recent years,many researches about the issues have been done,and a lot of progresses have been obtained.In this paper,the several aspects of research progresses,including thermodynamic and hydrological characteristics of surface land processes in arid regions,structure of atmospheric boundary layer in arid regions,parameters and parameterization of surface land processes in arid regions,theory of atmospheric boundary layer of heterogeneous underlying surface,the characteristics of atmospheric boundary layer and pollutant mechanism of a arid valley city,etc.have been summarized and concluded.And the present scientific problems and the future important scientific points are discussed.更多还原
