摘    要:根据入渗、产流原理,分析了小流域土壤侵蚀正态模型试验中的产流与流域实际产注过程的差异,首次提出了模型产流畸变的概念。并根据实地人工降雨试验所计算的入渗、产流过程线,理论推导出不同比例尺正态模型畸变系数,同时随着模型相似比例尺的减小,产流畸变系数增大。产流畸变系数的提出,提高了土壤侵蚀正态模型试验的实际应用价值,也告诫人们用模型试验资料时,必须进行模型与原型的转换,否则会造成水保措施工程设计的浪费。

关 键 词:土壤侵蚀  正态模型  产流方式  畸变系数  水土保持  蓄满产流  超渗产流

Abstract:In this paper, according to principle of runoff formation and infiltration, the difference of runoff formation between the prototype and the normal mock-up of small drainage was analyzed, and the conception of runoff formation distortion in soil erosion experiment of the mock-up of small drainage was put forward for the first time. Again on the basis of process curve of runoff formation and infiltration obtained by the test of artificial simulation rainfall on typical slope in Liudao gully drainage, the runoff formation distortion coefficient of the normal mock-up of small drainage in various scale was calculated theoretically. It improved applicable value of test of soil erosion with normal mock-up of small drainage. And it exhorted people to transform mock-up to prototype by multipling runoff formation distortion coefficient and tested figures when tested data were applied. Otherwise, the wasting phenomenon of project design in soil and water conservation would be caused.
Keywords:Soil erosion  Normal mock-up  Runoff formation  Distortion coefficient
