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（2012—2013年）日降雨量、实测径流和修正SCS—CN模型，率定集雨垄的径流模型参数CN、λ和α，然后利用后3年（2014—2016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，λ取值范围分别为0.045~0.071，0.251~0.327，0.189~0.213，α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SCS—CN模型参数CN、λ和α的影响不明显，不同覆盖材料之间的CN、λ和α差异远大于不同垄宽之间的CN、λ和α差异。修正SCS—CN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。

Abstract

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 SCS-CN model was used to estimate the runoff for ridges with 3 widths (30

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

and α in the modified SCS-CN model were calibrated according to the rainfall and runoff from 2012 to 2013

and the applicability of the modified SCS-CN 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 SCS-CN model ranged from 82.0 to 82.9

from 97.9 to 98.8

and from 98.3 to 99.9

respectively; The parameter of λ ranged from 0.045 to 0.071

from 0.251 to 0.327

and from 0.189 to 0.213

respectively; The parameter of α ranged 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 Nash-Sutcliffe 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

and α in the modified SCS-CN model. The difference of CN

and α between 3 different materials was greatly larger than that between 3 ridge widths. The Nash-Sutcliffe efficiency was higher than 0.95 and the relative error was lower than 10%. The results indicated that the modified SCS-CN 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.
