【摘要】：采用室內(nèi)人工模擬降雨試驗(yàn),研究了黃土質(zhì)地對(duì)坡面侵蝕的影響,并探討了降雨、地形(坡度和坡長(zhǎng))及黃土土質(zhì)對(duì)坡面侵蝕的綜合作用。試驗(yàn)設(shè)計(jì)包括3種質(zhì)地黃土(黃綿土、黑壚土和X土)、4個(gè)坡度(10°,15°,20°和25°)、2個(gè)坡長(zhǎng)(5m和10m)和2個(gè)總降雨量相同的降雨強(qiáng)度(90,120mm/h)。結(jié)果表明:在相同降雨條件下,X土降雨過(guò)程中入滲緩慢,產(chǎn)流時(shí)間快于黑壚土與黃綿土,X土坡面的徑流總量高于黑壚土和黃綿土坡面。坡度對(duì)單寬產(chǎn)流率無(wú)影響。各因子按對(duì)單寬產(chǎn)流率影響程度從大到小依次為坡長(zhǎng)、雨強(qiáng)、粘粒含量和有機(jī)質(zhì);各因子按對(duì)單寬產(chǎn)沙量按影響程度從大到小依次為坡長(zhǎng)、土壤顆粒幾何平均直徑、雨強(qiáng)、有機(jī)質(zhì)含量和坡度。
[Abstract]:The effects of loess texture on slope erosion were studied by artificial rainfall simulation in laboratory, and the comprehensive effects of rainfall, topography (slope degree and slope length) and loess soil quality on slope erosion were discussed. The experimental design includes three types of loess (loess soil, black loessial soil and X soil), four slopes of 10 擄, 15 擄, 20 擄and 25 擄, two slopes of 5 m and 10 m) and two rainfall intensities of 90120 mm / h with the same total rainfall. The results showed that under the same rainfall conditions, the infiltration rate was slow and the runoff production time was faster than that on the slope surface of black loessial soil and yellow loessial soil, which was higher than that of black loessial soil and yellow loessial soil. The slope has no effect on the rate of single width runoff. The influencing degree of each factor is slope length, rain intensity, clay content and organic matter, and slope length, geometric average diameter of soil particle, rain intensity according to the influence degree of single width sediment yield from large to small, each factor is the length of slope, the geometric average diameter of soil particle, and the rain intensity, according to the influence degree of single width sediment yield. Organic matter content and slope.
