摘要

采用SWAT模型研究淮河上游土地利用变化对产沙的影响。在模拟含沙量的基础上，分析了土地利用变化对土壤侵蚀模数和降雨产沙关系的影响。结果表明:在相同的降雨、土壤条件和坡度条件下，林地、水田和农田的产沙量均呈上升趋势;研究结果可为淮河上游的水土保持和河流健康保护提供参考。

Modeling the effects of land-use change on sediment yield in the upper Huaihe river basin, China

SWAT model was selected to investigate the effects of land-use change on sediment yield in the upper Huaihe river. On the basis of the simulated sediment concentration, the effects of land-use change on soil erosion modulus and rainfall-sediment yield relationship were analyzed. The results showed that under the similar rainfall, soil condition and slope, the sediment yields ascended with woodland, paddy field and farmland. The outputs could provide references for soil and water conservation and river health protection in the upper stream of Huaihe River.
