大孔径闪烁仪观测地表水热通量研究进展
Research Progress of Surface Water and Heat Flux Observation with Large Aperture Scintillometer
中文摘要：
地表水热通量（感热通量和潜热通量）作为陆地表面热量平衡的重要组成部分，是气象、农业、水文和生态等领域的重要研究内容。20世纪末兴起的大孔径闪烁仪（LAS）可以观测复杂下垫面的平均水热通量。在介绍LAS原理的基础上，综述了LAS的可用性、研究观测的相关问题和实际应用三方面研究进展，为LAS的进一步研究提供帮助。

Abstract：
As important parts of land surface heat balance, surface fluxes of water and heat (sensible heat fluxes and latent heat fluxes) are crucial research subjects in meteorology, agriculture, hydrology and ecology. The large aperture scintillometer (LAS) developed at the end of the 20th century can obtain the average water and heat fluxes over complex surfaces. After introducing the principle of LAS, this paper reviewed the research progress of LAS in three aspects: the usability, the related problems in observation, and the practical application, so as to provide help for the further research of LAS.
