摘　　要：在3S技术和基础信息数据库的支撑下,应用SWAT模型对招苏台河流域径流和泥沙进行了模拟研究,利用2004—2009年的日径流量、输沙率等水文实测数据对模型进行校准和验证,评价参数满足要求。模拟结果表明:研究区年平均径流量和输沙量为1.64m3/s、6.90万t,土壤侵蚀模数为62.93t/(km2·a),侵蚀强度为微度侵蚀,耕地的土壤侵蚀模数最大,是该河泥沙的主要来源;径流量和输沙量在时间分布上具有季节性特点;根据研究区的水土流失特征,提出拟采取的水土保持措施,并模拟了河流两岸不同尺度植被缓冲带控制情景条件下的水文响应。该研究揭示了招苏台河流域径流和泥沙产生的规律和特征,为研究区水土保持和重污染河流的治理提供数据和管理决策支持。This research simulated runoff and sediment of Zhaosutai river basin based on SWAT model, 3S technology and basic database. The data of daily runoff and sediment transport rate from 2004 to 2009 were used to calibrate and validate the results of the model output. It proved that SWAT model was feasible for the research. Simulation results showed that average annual runoff was 1.64 m3/s and sediment discharge was 6.90× 104 t. Soil erosion modulus was 62.93 t/（km2 · a）, which was categorized as slightly erosion . Cultivated land was the main source of sediment generation in the research area. From the results of SWAT model, runoff and sediment discharge were ranged with season. According to the characteristics of the study area, the soil and water conservation measures were proposed, and hydrological response of scenarios of different control measures of vegetation buffer zone with different scales were simulated. This research reveals the characteristics of runoff and sediment in Zhaosutai river basin, and provides data and management decision support for soil and water conservation for the study area.
