摘　　要：文中归纳总结了公益性行业(气象)科研专项项目"藏东南地区复杂下垫面地气交换观测研究(GYHY201206041)"的主要研究成果。本项目观测试验、理论研究与模型模拟相结合,开展了藏东南地区复杂下垫面地气交换特征研究,揭示了复杂下垫面上地气交换的非均匀性;开展了数值模式地气交换参数化方案在藏东南地区的适应性评估,为数值模式适应能力的改进提供了思路;开展了卫星遥感反演技术及产品在藏东南地区的检验订正研究,探索了利用多点观测值综合描述复杂下垫面上地气交换特征的转化方法。研究成果有利于深入了解藏东南地气交换特征并可为复杂下垫面地区地气交换观测试验设计提供技术参考。With the help of the special fund for meteorological research in the public interest project ＂ Experiment study of the surface-to-air exchange on the complicated underlying surfaces over the Southeast Tibet（ GYHY201206041） ＂,combining of observation experiment,theoretical research and numerical simulation,the characteristics of the surface-to-air exchanges over the Southeast Tibet was analyzed. Firstly,there were inhomogeneous surface-to-air exchange because of the inhomogeneous land cover over the Southeast Tibet. Secondly,according to the observation data,the adaptability of multiple parameterization schemes was tested by using the Weather Research Forecast（ WRF） model,which may provide some suggestions to improve the parameterization scheme of surface-to-air exchange for the WRF model. Thirdly,satellite remote sensing retrieval methods and the products of satellite remote sensing are validated and tested based on the observation data,which is beneficial to the promotion and application of remote sensing techniques in the Southeast Tibet. Above all,the research could provide technical and methodological reference for the scheme design of surface-to-air exchange field observation experiment,variability analysis of surface-to-air exchange,improvement of the parameterization schemes of surface-to-air exchange and product correction of remote sensing products on the complicated underlying surfaces.
