摘　　要：AnnAGNPS是一个批处理、连续模拟流域尺度的分布式农业模型,其根据水文特征将流域划分成若干同质分室或集水单元,模拟流域内每个水文单元和流域整体输出的径流、泥沙、养分和农药的负荷.本文以三峡库区小江流域为例,介绍了构建该模型所需要的气象、地形、土地利用、土壤、作物、非作物、作物管理、施肥、农药、径流曲线等参数的方法.AnnAGNPS, as a distributed agricultural model of batch process and continuous simulation of the watershed-scales, is used to simulate quantities of runoff, sediment, nutrients, and pesticides in each individual hydrological cell and their subsequent travel through the watershed by subdividing studied wa- tershed into homogenous cells or subcatchments according to hydrologic characteristics. The present re- search introduces methods of constructing data set for AnnAGNPS in the case of Xiaojiang River watershed located in the Three Gorges Region. The data set mainly focuses on climate, topography, land use, soil, crop, non-crop, crop management, fertilizer, pesticide information and runoff curve number data.
