| 摘 要： | 采用人工模拟降雨方法,分设3种不同的降雨强度,研究了宁南山区人工草地和坡耕地的产流产沙特征。结果表明：人工草地与坡耕地的径流量最高分别为14.55、14.21 mm;侵蚀模数坡耕地最高为15.5 t/km^2,人工草地最高为10 t/km^2。人工草地和坡耕地的径流量、侵蚀模数均随降雨强度的增加而增加,并与降雨强度呈指数函数或幂函数。

| Abstract: | The characteristics of sediment and runoff yield on grassland and plowland were studied by adopting artifi-cial rainfall simulation With 3 different rainfall intensity in the Southern Ningxia region.The results showed that in the three artificial simulation of rainfall,the maximum runoffs of grassland and plowland were 15.55mm and 14.21mm re-spectively,and the maximum soil erosion of grassland and plowland were 15.5t/km 2 and 10 t/km 2.The grassland and plow-land runoff and soil erosion were increased with ... |
