中文摘要利用人工模拟降雨试验,通过观测作物不同生长阶段、不同坡度径流量和土壤流失量的动态变化过程,研究作物和坡度对坡面土壤侵蚀的共同影响。结果表明:作物和坡度均对坡面径流的形成、发展产生较大的影响。与裸地相比,种植玉米条件下,坡面地表径流量平均减少23.80%,土壤流失量平均减少44.25%,玉米对坡面产流产沙的抑制作用随玉米生长逐渐增强,坡面产流产沙量均随坡度的增加而增大。作物幼苗期的坡面径流量和土壤流失量主要受坡度的增强作用控制,至作物生长旺盛期,作物种植对坡面产流产沙的抑制作用成为主导因素。作物的存在可在一定程度上削弱坡度对产流产沙的增加作用,有效降低坡面的水土流失量。
英文摘要Abstract:In order to investigate the interaction of crop cover and slope gradient on runoff and sediment yield,
this study observed the dynamics of runoff and sediment losses at different growth stages with different slope
gradients by simulated rainfall.The results showed that both crop cover and slope gradient had considerable
effects on formation and development of runoff.Compared to bare soil,the average runoff amount and
sediment yield reduced by 23.80%and 44.25%,respectively in corn field.The inhibition effects of corn on
runoff and sediment yield gradually increased as corn grew.Under crop cover,both runoff and sediment yield
increased with increasing slope gradients.At the seedling stage of corn,slope gradients had significant
effects on amount of runoff and sediment yield.Crop cover became the dominant factor which affected runoff
and sediment yield till the full growth stage.Crop cover could reduce the increment of runoff and sediment
yield in a certain degree and soil and water losses.
