摘要
[目的]探寻准确、有效的方法研究蚂蚁河流域土壤侵蚀状况。[方法]利用WEPP模型对蚂蚁河流域的侵蚀状况进行定量研究,得到近30年来蚂蚁河流域的土壤侵蚀分布状况,并结合模型参数进行分析。[结果]该流域土壤侵蚀较严重的区域位于东南部和北部,侵蚀量总体由中间向四周先逐渐降低后又升高。对所得到的侵蚀量进行换算,结果显示,该研究区的平均侵蚀模数范围为0~1 020t/（km2·a）,属于微度和轻度侵蚀。[结论]WEPP模型的应用为东北黑土区土壤侵蚀预报提供一种可行方案,也为水土保持规划提供依据。
[Objective] The aim was to find an accurate and effective method for study soil erosion status in the Ant River basin. [Method]WEPP model was used for quantitative research on the erosion of the Ant River region to get soil erosion distribution results in the nearly 30 years and combined with the model parameters for analysis. [Result] The soil erosion serious area in the basin was located in the southeast and the north,and the total amount of erosion was gradually decreased and then increased from the central to the surrounding area. The obtained erosion amount was converted. The results showed that the average erosion modulus of study area was 0- 1 020 t /（ km2·a）,which belongs to the micro degree and slight erosion.[Conclusion]The application of WEPP model provides a feasible scheme for the northeast black soil area to predict soil erosion and the basis for soil and water conservation.
