| 中文摘要: |
| 藤条江是南亚重要国际河流元江-红河的主要支流,流域地处高原山地,土壤侵蚀严重。利用分布式水文模型SWAT对藤条江流域的水文过程进行了模拟,采用2年的逐日观测数据对模型进行了率定和验证。径流模拟结果和实测数据相比,模型确定性系数和效率系数(纳什-克里夫系数)均高于0.75,表明SWAT模型对藤条江径流的模拟结果良好。使用率定好的模型,计算出流域年均土壤侵蚀量为94.39 ×104t,约47%的流域面积处于中度侵蚀状态,流域的水土流失关键区位于红河断裂带南缘,需优先实施水土保持措施的行政区域对应云南省金平县。 |

| Tengtiao River, a main tributary of Yuan River-Red River located in south-east part of Yunnan Province, which has been experiencing an intensification of agriculture and serious soil erosion. The SWAT ( Soil and Water Assessment Tool) model, a soil water , sediment , and nutrient transformation and simulator for agricultural watershed, was applied to this catchment of indentify the critical areas of soil erosion within the study area. The simulation efficiency ( Nash-Suttcliffe efficiency coefficient) of SWAT model in validation period is 0.75 , and based on the simulation results of the model, the average annual steam flow of Tengtiao River is 48.46 ×108 m3; the average annual soil loss is 94.39 ×104t and 47% area of the basin is in the moderate erosion. The results provided scientific basis for degigning measurement for ecosystem restoration and sound land management , which were especially useful for the researches on distributed hydrological model application in plateau mountainous watershed. |
