综述了陆—气相互作用在观测、机制和模型方面的最新进展，指出现有陆—气相互作用观 测研究还没有同时考虑陆面生理生态与大气边界层变化对陆—气通量影响，制约着陆面过程参数 化或参数的卫星遥感反演以及陆面过程模式的业务应用。从全面认识陆—气相互作用与陆面过 程模式发展出发，指出未来需进一步强化陆面生理生态与大气边界层变化对陆—气相互作用的影 响研究以及陆面过程模式的业务应用研究，并提出了拟关注的重点任务：①陆—气相互作用的跨 界面立体观测；②多源数据在跨界面陆—气相互作用中的应用；③陆面过程模式发展与业务应用。

The paper summarizes recent progress in the observation, mechanism and model of landatmosphere interaction, and pointed out that the existing observational studies have not taken into account the effects of both the changes of terrestrial ecophysiology and atmospheric boundary layer on land-atmosphere fluxes. As a result, they restrict the parameterization of land surface process, parameter inversion from satellite remote sensing, and the operational application of land surface process model. In order to realize comprehensive understanding of land-atmosphere interaction and the development of land surface process models, it is pointed out that the studies on the effects of changes in terrestrial ecophysiology and atmospheric boundary layer on landatmosphere interactions and the operational application of land-surface process models are needed to be emphasized in the future, the main tasks to be concerned include: (1) three-dimensional observation of the landatmosphere interaction across the boundary layer, (2) application of multi-source data in the land-atmosphere interaction across the boundary layer, (3) development and operational application of land surface process model.
