摘　　要：为了选取适合于紫色土流域的机理模型,同时为控制紫色土丘陵区的农业非点源污染,以及为三峡库区内非点源污染物输出与控制提供科学依据,本文将2种机理参数模型AnnAGNPS与SWAT运用到不同土地利用方式下的紫色土小流域,对地表径流和非点源污染物的输出模拟进行研究。通过适用性研究发现:2种模型对紫色土流域的径流量模拟效果最为理想,平均误差为-7.5%和2.9%;而模型对流域的泥沙模拟效果均不理想,误差较大;对于养分迁移的模拟,AnnAGNPS模型的模拟效果要好于SWAT模型,平均误差控制在10%左右。因此,AnnAGNPS模型更适合在紫色土典型流域进行模拟运用,可获得可信度较高的模拟结果。In order to select the right model for the watershed of purple soil, and provide scientific basis for eontrolling the export of non-point source pollutant from the hilly area of purple soil and establish the monitoring model for Three Gorge Reservoir Area further, the research applied two water quality models： AnnAGNPS and SWAT to typical watershed of purple soil under different land using, and simulated surface runoff and non-point source pollutant export. Results showed that the effect that simulated surface runoff by two models was best, and the average relative error were -7.5% and 2.9%; the effect that simulated sediment was not ideal, error was rather big; the result simulating nutrient transport was that AnnAGNPS model was better than SWAT model, and the average error was about 10%. So AnnAGNPS was more suitable for applying to typical watershed of purple soil, and could gain higher reliability about simulated results.
