中文摘要:

以新安江上游屯溪流域为研究区域，建立了SWAT模型的气象、土壤、土地利用和农作物管理等数据库，并利用2000-2010年逐月实测的径流、泥沙及非点源溶解态氮负荷数据进行了多参数、多站点的率定和验证，使用多目标（纳氏系数、线性相关系数和相对误差）对模型适用性进行了评价。结果表明：径流模拟效果非常好，泥沙和营养盐模拟结果令人满意，SWAT模型在屯溪流域适用性较好，可以模拟分析该地区的非点源污染问题，研究所构建的数据库和率定的参数可为进一步研究新安江流域的水环境管理提供科学依据和决策支持。

英文摘要:

Taking Tunxi watershed in the upper of Xin'an river as study area,the paper built the database of SWAT model about weather, soil, land use and crop management.Based on the monthly observed runoff, sediment loads and dissolved nitrogen load data from 2000 to 2010, it carried out calibration and validation of multi-parameters, and multi-site .It evaluated the applicability and reliability of SWAT model in Tunxi watershed basin by use of multi-objective, Nash-Suttclife efficiency, linearly dependent coefficient and relative error. The results showed that the simulation of runoff is very good. The simulation results on sediment and nutrients salt are desirable. The model has good adaptability and may analyzed the non-point pollution problems in Xin'an river basin.The constructed database and calibrated parameters can provide a reliable scientific basis and decision support for the further water environmental management in the basin.
