摘要:
采用SWAT模型，在GIS技术和流域基础信息数据库的支持下，对研究区径流和泥沙进行了模拟研究，利用2006—2009年的日径流和泥沙监测数据对模型进行了校准和验证，验证结果表明SWAT模型适用于研究区。结果表明：区内土壤侵蚀强度以微度为主，年均泥沙量为15.395万t；不同土地利用方式下的土壤侵蚀模数不同，耕地土壤侵蚀模数最大为475.84t/（km2·a），泥沙量占总量的94.4%，且季节性较强，在7月、8月的产沙量占全年总量的67.9%；年均入库水量和入库泥沙分别为10.899亿m3、8.265万t，其中浑河流域贡献率最大，其次为苏子河流域。本研究揭示了辽宁省主要城市供水水源的大伙房水库汇水区水土流失规律，为水土保持和面源污染防治提供了重要基础支持。
Abstract:
This study simulated the stream flow and sediment based on SWAT model in Dahuofang reservoir catchment,GIS technology and basic information database of watershed.The calibration and validation of streamflow and sediment were performed from 2006 to 2009,and the results showed that SWAT model could be applied to study area very well.The results of model evaluation showed that the annually amount of soil erosion was 1.539 5×105t,which was low-grade erosion in the category.Soil erosion rate was 475.84t/(km2·a) in cultivated lands,and the ratio of sediment yield which was brought to river from cultivated lands was 94.4%.Reservoir inflow was 1.089 9×109m3 and sediment flux into the reservoir was 8.265×104t,and the Hunhe River had the largest contribution,followed by Suzi River.Sediment yield was highly different all the year around,and the ratio of sediment yield was 67.9% in July and August out of the whole year.This research reveals the soil erosion regulation in catchment area of Dahuofang Reservoir serving as the water source of major cities in Liaoning Province,and provides important basic support for soil and water conservation and the prevention of non-point source pollution.
