SWAT模型参数移植法缺资料地区非点源污染模拟研究

为了解决资料稀缺流域非点源污染研究中分布式物理模型无法直接应用的问题，基于SWAT（Soil and Water Assessment Tool）模型，采用参数移植法构建了无径流无泥沙资料的西充河流域（西充境内）非点源污染模拟方案。验证流域模拟结果良好（R2>0.8，NSE>0.5）表明SWAT模型径流泥沙参数可用于相似流域移植，研究区西阳寺断面TP（R2=0.52，NSE=0.69，Re=35%）水质模拟结果说明基于径流泥沙参数移植后的SWAT模型可用于进一步非点源污染模拟研究。

Non-point Source Pollution Simulation Study based on SWAT model Combined with Regionalization Method in Data Scarce Catchment

In order to solving the problem of the distributed non-point source pollution models difficultly applying in data scarce catchments, a case study was conducted in the XiChong river basin within XiChong County based on SWAT model combined with parameter transplant regionalization method. Verifying basin satisfactory results (R2 > 0.8, NSE > 0.5) showed runoff and sediment parameters transplantation had some applicability for SWAT. Results of study area indicated SWAT combined with runoff and sediment parameters transplantation can be used for further simulation of non-point source pollution.
