摘　　要：地表固有的非均匀性影响近地层大气的垂直结构,甚至改变局地天气条件,亦使得大气数值模式大尺度网格面积水热通量的计算对其具有较强的敏感性。为了提高气候模式性能,非均匀陆面过程参数化已是当前大气边界层和陆面过程模式研究的热点和难点问题之一。本文在调研国内外大量文献的基础上,综述了近年来非均匀地表陆面过程参数化的研究现状,分析和比较了不同的参数化方法的优缺点以及数值模式模拟结果对它们的响应,提出了目前尚待继续探讨和解决的几个关键性问题。Land surface heterogeneity （LSH）, which is ubiquitous in nature, have an effect on the vertical structure of atmospheric surface layer, and even change the local weather condition. There is also a marked sensitivity of model grid sensible and latent heat fluxes calculated in large scale to the land surface sub-grid heterogeneity. So implemented the parameterization of LSH in the land surface model to enhance the accuracy of climate models forecast has become one of the key issues and difficulties of current research. Through looking up plenty of document information, this paper presented a review on process and advances in the parameterization of heterogeneous land surface. Compare and analysis among the different techniques that attempt to incorporate the effects of LSH in the mode over past several years is carried out. The response of numerical model simulation results to them is also discussed. Some key issues which are very unclear as yet and should be further investigated currently are point out at last.
