摘　　要：根系吸水对水循环起重要调控作用,开展根系吸水过程及参数方案研究,将加深对地表水文和生物地球化学过程的理解,对提高陆面过程模型乃至气候模式的模拟能力均起到促进作用。本文简述了植物根系吸水模型的发展进程,归纳了根分布、土壤水分对根阻影响函数及根系水分再分配作用参数方案的研究概况,指出现有陆面过程模型根系吸水参数方案存在的不足,提出未来发展方向,为相关研究提供参考。Root water uptake process controls water cycling. Researches on the root water uptake process and development of its parameterization scheme play an important role to understand surface hydrological and biogeochemical processes as well as to improve simulation performance of land surface and climate models. The paper resumed the root water uptake model progresses and induced parameterization schemes on root distribution, influence function of soil water content on root resistance and hydraulic redistribution and then pointed out shortcomings of root water uptake parameterization scheme in existing land surface models. Finally, we proposed the future development direction for similar studies as a reference.
