超渗产流是流域产流机制的一种基本模式,它符合我国北方干旱、半干旱地区的产流规律。陕北黄土高原沟壑区,长年干旱,夏季多暴雨,其历时短,强度大,下垫面黄土包气带厚达数十米,且植被较差,是超渗产流的典型地区之一。黄委会子洲径流实验站为这一地区积累了宝贵的径流实验资料。多年来,国内不少单位和学者,都曾依据上述资料,作过不少研究,提出不同的产流计算方法(见文献[1]至[6])。研究的侧
Ultra-seepage flow is a basic model of the river basin runoff mechanism, which accords with the law of runoff in the arid and semi-arid areas of northern China. In the gully area of Loess Plateau of northern Shaanxi, it has many years of drought and heavy rains in summer. Its lasted time is short and its intensity is large. The loess aeration zone on the underlying surface is several tens of meters thick with poor vegetation, which is one of the typical areas of ultra-seepage . The Yellow River Subproject Runoff Experimental Station has accumulated valuable runoff experimental data for this area. Over the years, quite a number of domestic units and scholars have made many studies based on the above information and proposed different methods for calculating runoff (see [1] to [6]).
