摘要:
针对2013年6—9月份安塞县马家沟多级梯田遭受暴雨侵蚀严重等问题，运用新一代水蚀预报模型WEPP模型对马家沟多级梯田在暴雨条件下的侵蚀情况进行模拟，并将WEPP模型模拟的结果与实测资料进行了对比。结果表明：WEPP 模型能够较好地模拟黄土丘陵区多级梯田在暴雨条件下的径流量以及土壤侵蚀量，随着梯田级数的增加，WEPP模型对径流量与侵蚀量的模拟精度逐渐降低。由于受该区地下水的影响，模拟径流量总体小于采用径流系数法算得的径流量，由于梯田田埂的防蚀作用，模拟土壤侵蚀量总体大于实测侵蚀量。研究为黄土丘陵区梯田防蚀以及梯田修筑提供科学依据及有效方法，为黄土丘陵区多级梯田的暴雨侵蚀预测提供了合理化建议。
Abstract:
With respect to the prob lem of serious rainstorm erosion of multi-level terraces in Majiagou river basin from June to September in 2013, this article used the WEPP model to simulate the soil erosion of rainstorm of multi-level terraces, and then compared the result of simulation with the observed data. The results show that WEPP model can well simulate the runoff and soil loss of multi-level terraces under rainstorm in Loess Hilly and Gully Region. With the increase of terrace level the precision of WEPP model of the simulation on runoff and soil loss reduced; simulation of runoff is less than the result calculated by runoff coefficient method due to the influence of the groundwater. Simulation of soil erosion is greater than the measured erosion as a whole because of the prevention erosion of the terrace ridge. This research result provided scientific basis and effective method for the terrace anticorrosive and terraces buildup and provided scientific basis for the forecast of multi-level terrace erosion under rainstorm in the loess hilly region.
