缺资料流域SWAT 适宜性模型校准新方法及应用
摘要: 基于SWAT 分布式水文模型, 以伊犁河上游流域为研究区域, 针对缺资料流域水资源评价关键问题,
发展了一套综合流域特征、多时间尺度、多变量和多站点的适宜性模型校准新方法, 应用中取得了较好的模
拟结果: 各站点在校准期和验证期均拟合较好, NSE 和r2均在0.6 以上, 最高达0.83, RE 均在8% 以内. 结果
表明模型在该校准方法下, 较好地再现了流域的水文过程, 其模拟结果可供流域水资源评价和管理参考.

A new suitable method for SWAT model calibration and its application in data-scarce basins
Abstract: The distributed hydrological model–SWAT– was applied to Yili river basin for tackling the important
problem of the water resources evaluation in data-scarce basin. A new suitable method for model calibration was
developed using multi-temporal scales, multi-variables and multi-sites incorporates characteristic of the basin.
Preferable simulation results were obtained: all the sites fit well in the period of calibration and validation, NSE
and r2were both above 0.6, with the highest being 0.83, and RE were all within 8%. The results indicate that in
this calibration method, the model represents the hydrological processes of the basin and the simulated results
can provide references for the evaluation and management of water resources of the basin.
