摘　　要：本文通过构建精细化的SWAT模型,对碧流河水库洪水期间流域营养盐的输出特征进行研究,并模拟不同管理措施削减流域营养盐输出的效果。结果表明,碧流河水库流域营养盐输出主要集中在洪水期间,营养盐负荷存在明显的空间分布差异,高负荷区域主要位于河流两岸的农田和居民用地。研究成果可为制定流域营养盐管理措施提供参考和依据。In this paper,a refined SWAT model was constructed to study the characteristics of nutrient output in Biliuhe Reservoir during flood,and the effect of different management measures to reduce nutrient output in the basin was simulated.The results showed that the nutrient output of Biliuhe reservoir was mainly concentrated during the flood period,and the spatial distribution difference of nutrient load was obvious.The high load area was mainly located in the farmland and residential land on both sides of the river.The research results can provide reference and basis for formulating nutrient salt management measures in river basin.
