摘要

运用人工模拟降雨研究了裸地及不同盖度沙打旺草地产流产沙过程。结果表明：裸地产流产沙过程可用指数函数ｙ＝ｅａ＋ｂｘ型式描述；不同盖度的沙打旺草地产流产沙过程均可用幂函数ｙ＝ａｘｂ来描述，且随着盖度由大向小变化，方程参数ａ值减小，ｂ值增大。

Abstract

The process of runoff and sediment yield in bareland and Astragulus adsurgens of different coverage were studied by means of artificial simulated rainfall. The results showed; the process of runoff and sediment yield were exponential (ｙ＝ｅａ＋ｂｘ) distribution in bareland

and were power (y=axb) distribution in Astragulus adsurgens grassland. When coverage varied from high to low

the parameter a decreasing

and b increasing.
