摘要:
SWAT模型是基于水文过程的、具有很强物理机制的流域分布式水文模型。基于AVSWAT2005模型灵敏性分析模块，在典型中尺度流域——北京密云县红门川流域应用与验证。通过灵敏性分析，得到影响该流域产流模拟结果精度的主要参数因子，SCS径流曲线系数（CN2）、土壤可利用水量（SOL_AWC）、基流α系数（ALPHA_BF）的影响是显著的，是最敏感因子。同时调整参数值，采用1991-2006年的实测月流量数据对模型进行了校准和验证，结果表明：模型对月流量模拟的相对误差在模型校准期和验证期均小于15%，决定系数R2大于0.8，Nash-Suttcliffe系数Ens高于0.7，SWAT模型对红门川流域产流的模拟结果良好。因此，SWAT模型中的灵敏性分析模块可以应用在面积较小的中尺度流域，具有一定的推广意义。
Abstract:
The soil and water assessment tool (SWAT) is a physically-based continuous event hydrologic model. This paper mainly introduces the sensitivity analysis model of the module AVSWAT 2005 principle, application and verified in Hongmenchuan watershed. Based on the sensitivity analysis, the main parameters affecting the simulated values in this watershed were determined, the CN2、the SOL_AWC and the SOL_K were the significant and sensitive parameters. Adjusting the parameters based on the analyzed results, using 1991 to 2006 continuous simulations on monthly runoff, satisfied simulation results were obtained with the relative error was under 15%, Nash-suttcliffes coefficient (Ens) more than 0.7, and correlation coefficients R2 exceeding 0.8, SWAT model of Yunzhou reservoir basin simulation result is good. Therefore, the application of sensitivity analysis module of SWAT model in soil-gravel area in middle-scale watershed of smaller area has improved the accuracy of simulation dramatically.
