摘    要:本文回顾了近年来中国科学院大气物理研究所在陆面水文过程的观测、模式发展以及陆气相互作用研究等方面所取得的重要研究成果。首先概述了近年来在中国区域所开展的陆气相互作用野外观测试验,通过资料分析揭示了国际上现有陆面模式对干旱/半干旱地区陆气相互作用模拟的偏差,指出典型干旱/半干旱区陆面过程参数修正的必要性;随后重点描述了陆面过程模式中积雪覆盖度和冻土参数化方案的发展,中国区域土壤湿度的时空分布特征及其对区域气候的影响,以及中国区域大尺度水文模式的研制和应用等;最后给出了陆面水文过程研究的趋势和发展方向的展望。

关 键 词:陆面过程  水文模式  陆气相互作用  土壤湿度  地下水

Abstract:This paper reviews recent advances in the field observation of land-atmosphere interaction,the development of land-surface and hydrological model,and the impact of land surface processes on the regional climate variations at the Institute of Atmospheric Physics,Chinese Academy of Sciences.Firstly,the field campaigns over different characteristic land surfaces have been briefly summarized,and the discrepancies of current land surface models in the simulation of land-atmosphere interaction over arid and semi-arid regions have been revealed by using the field observation data,and the necessity of the parameter calibration for the land surface model has been pointed out;then,the development of land surface model have been introduced,with focus on the parameterization of fractional snow cover and permafrost processes;the spatial-temporal distribution of soil moisture and its importance in the weather forecast and seasonal climate simulation and prediction have also been introduced in this paper,together with the development of large-scale distributed hydrological model system and its applications over China.Finally,the prospects for studies of the land-surface and hydrological processes are briefly discussed.
Keywords:land-surface process  hydrological model  land-atmosphere interaction  soil moisture  ground water
