摘要:
为模拟流域土壤侵蚀状况，分析土地利用方式对土壤侵蚀的影响，构建抚河流域SWAT模型。应用SWAT模型对研究区的径流、产沙状况进行了校准和验证，在此基础上分析了抚河流域土壤侵蚀强度特征，探讨了不同土地利用方式对产沙的影响。结果表明：4个测站月径流、月输沙量的校准期和验证期的决定系数（R2）均在0.7~0.93之间，Nash-Sutteliffe效率系数（NSE）在0.64~0.92之间，径流、泥沙模拟结果达到满意精度，模型在本区域具有良好的适用性；土壤侵蚀以微度侵蚀和轻度侵蚀为主，城乡及工矿用地的土壤侵蚀模数最大，而林地的产沙量绝对量最大。研究成果可为研究区水土保持提供参考。
Abstract:
In order to simulate the condition of soil erosion, and analyze the effect of land use on soil erosion, the SWAT (Soil and Water Assessment Tool) model has been built for the Fuhe watershed of Jiangxi Province. SWAT model was adopted to simulate the hydrologic and soil erosion processes of the Fuhe watershed. On this basis, the characteristics of the soil erosion modulus in the Fuhe watershed were analyzed, and the effect of land use type on the sediment yield was discussed. The results showed that the determination coefficient (R2) of the monthly flow and sediment loading for 4 observation station are between 0.7 and 0.93 in the calibration and validation period, and Nash-Sutteliffe efficiency (NSE) were between 0.64 and 0.92. The simulation precision was pretty well, and the results of the runoff and sediment simulation has higher reliability. SWAT model could be successfully used for simulation in this area. Slightly-erosion and light-erosion were the main soil erosion types. The soil erosion modulus of non-agricultural land was maximal, and the sediment yield of woodland was maximal. The research results can provide reference for soil and water conservation of study area.
