中文摘要	为了探寻半干旱区垄沟集雨种植控制水土流失和增产的机理,利用前2年(20122013年)日降雨量、实测径流和修正SCSCN模型,率定集雨垄的径流模型参数CN、lambda和alpha,然后利用后3年(20142016年)日降雨量和实测径流资料检验该模型有效性,预测不同覆盖材料(土壤结皮、生物可降解地膜和塑料地膜)和不同垄宽(30,45,60 cm)集雨垄的径流量。结果表明,土壤结皮覆盖集雨垄、生物可降解膜覆盖集雨垄和塑料地膜覆盖集雨垄的CN取值范围分别为82.0~82.9,97.9~98.8,98.3~99.9,lambda取值范围分别为0.045~0.071,0.251~0.327,0.189~0.213,alpha取值范围分别为2.35~2.89,4.21~4.82,3.32~3.99。通过对模型有效性进行评价,土壤结皮覆盖集雨垄、生物可降解膜覆盖集雨垄和塑料地膜覆盖集雨垄的平均相对误差取值范围分别为1.36%~3.41%,1.21%~3.42%,2.48%~5.42%,纳什效率取值范围分别为0.97~0.98,0.97~0.98,0.96~0.98。日降雨量等级对修正SCSCN模型参数CN、lambda和alpha的影响不明显,不同覆盖材料之间的CN、lambda和alpha差异远大于不同垄宽之间的CN、lambda和alpha差异。修正SCSCN模型集雨垄径流预测的相对误差满足要求(≤20%),可信度较高(纳什效率≥0.95),可以用于半干旱区集雨垄的径流预测,为控制水土流失和提高降水利用效率提供科学方法。
英文摘要	In order to find the mechanism of soil erosion control and crop yield increase in ridge-furrow rainwater harvesting production in semi-arid regions of China,a modified SCSCN model was used to estimate the runoff for ridges with 3 widths(30,45,and 60 cm)and 3 different materials(soil crust,biodegradable film,and plastic film)based on the rainfall and runoff from 2012 to 2016.The parameters of CN,lambda,andalphain the modified SCS-CN model were calibrated according to the rainfall and runoff from 2012 to 2013,and the applicability of the modified SCSCN model to rainwater harvesting ridges was evaluated using rainfall and runoff from 2014 to 2016.The results indicated that for ridges mulched with soil crust,biodegradable film,and plastic film,CN in the modified SCSCN model ranged from 82.0 to 82.9,from 97.9 to 98.8,and from 98.3 to 99.9,respectively;The parameter oflambdaranged from 0.045 to 0.071,from 0.251 to 0.327,and from 0.189 to 0.213,respectively;The parameter ofalpharanged from 2.35 to 2.89,from 4.21 to 4.82,and from 3.32 to 3.99,respectively;Mean relative error ranged from 1.36%to 3.41%,from 1.21%to 3.42%,and from 2.48%to 5.42%,respectively;the NashSutcliffe efficiency ranged from 0.97 to 0.98,from 0.97 to 0.98,and from 0.96 to 0.98,respectively.Effects of classification of daily rainfall were not obvious on the parameters of CN,lambda,andalphain the modified SCSCN model.The difference of CN,lambda,and alphabetween 3 different materials was greatly larger than that between 3 ridge widths.The NashSutcliffe efficiency was higher than 0.95 and the relative error was lower than 10%.The results indicated that the modified SCSCN model was applicable to runoff estimation for rainwater harvesting ridges and the model performance was acceptable.These findings may be helpful in controlling soil erosion and increasing rainwater use efficiency.
