Abstract
坡面侵蚀预报模型的研究可加深对土壤侵蚀过程及其机理的认识,为坡面水土保持措施配置提供科学支持。我国坡面侵蚀预报模型研究大体可分为三个阶段:(1)利用主要水蚀区径流小区观测资料,基于美国通用土壤流失方程USLE(UniversalSoilLossEquation)建立坡面侵蚀预报统计模型研究;(2)结合黄土高原侵蚀特点,考虑陡坡地浅沟侵蚀,建立坡面侵蚀预报经验模型研究;(3)基于物理成因的坡面侵蚀预报模型研究。根据我国坡面侵蚀产沙的特殊性及地形的复杂性,提出建立我国坡面侵蚀预报模型应加强的研究领域,即浅沟侵蚀过程及机理、坡面薄层水流、细沟水流以及浅沟水流的水流剥离方程、坡面水沙汇集传递关系和陡坡地侵蚀过程模拟等研究
