摘要:AnnAGNPS3模型为针对农业非点源污染的非点源污染负荷估算模型,从方便该模型在中国应用的角度出发,
以辽河重要支流柴河上游流域为例建立了适合该流域的 AnnAGNPS 模型土壤数据库,并着重介绍了土壤数据库中土
壤质地的转换及相关参数的获取方法。基于建立的土壤数据库对 AnnAGNPS 模型在该流域的适用性进行了检验,结
果表明 AnnAGNPS 模型适合在该流域适用即表明建立的土壤数据库能够为 AnnAGNPS 模型在该地区使用。

Abstract: The AnnAGNPS model is a tool to predict the load of non-point source pollution from agriculture. In this paper a soil
database for AnnAGNPS was construction on the case of ChaiHe river’s upper reaches. The methods of soil texture
transforming were introduced as well as getting related parameters. Based on the established soil database the applicability of
AnnAGNPS in this area was examined. As the results show the AnnAGNPS can be used in this area which means the
established soil database was active.
