主要从坡面流流态对坡面流阻力的影响、坡面流阻力与雷诺数的关系、降雨对坡面流阻力的影响、坡面流阻力公式4个方面对前人关于坡面流阻力的研究成果进行了总结。结果表明：坡面流流态的不确定性导致了坡面流阻力变化更为复杂；坡面流阻力与雷诺数之间并无良好单一的相关关系；降雨对坡面流阻力有很大的影响作用但具体影响机理并未有明确的结论；坡面流阻力公式表征仍用明渠水流概念及表达方式，并且3个阻力系数n、f、C哪个更适合表征坡面流阻力尚无统一的结论。进而对目前存在的问题进行了分析，对今后的发展进行了展望，认为需在研究方法和实验设备及量测技术方面有所突破，才可以更好的对坡面流阻力进行全面系统的研究。

The predecessors'research results about the overland flow resistance are summarized from the fol-lowing four aspects that the influence of overland flow resistance on slope surface flow pattern, the relation-ship between overland flow resistance and Reynolds number, the influence of rainfall on slope surface flow resistance, and overland flow resistance formula characterization.The result indicated that the uncertainty of slope surface flow pattern led to the more complicated change of overland flow resistance;there is no single good correlation between the overland flow resistance and Reynolds number;rainfall has a great influence on slope surface flow resistance but the specific influence mechanism is not clear;open channel flow concept and expression are still used in characterization of overland flow resistance formula, and there is no unified conclusion that which is more suitable for characterization of overland flow resistance of three resistance co-efficients n、f、C.The paper analyzed the existing problems and prospect the future development as well.In order to study the overland flow resistance in a more comprehensive and systematic way, it is necessary for us to make a breakthrough in research method, experiment equipment and measurement technology.
