摘要:
以灞河上游罗李村子流域为研究区，基于子流域2001—2010年日尺度气象水文数据和流域地形、土壤和土地利用数据，构建了AnnAGNPS（Annualized Agricultural Non-point Source Pollution model）模型数据库，确定了最优子流域划分方案，模拟了流域年、月、日尺度径流变化。结果表明：（1）当临界源面积（CSA）取100 hm2，最小初始沟道长度（MSCL）取70 m时，模型将流域划分为1 030个分室，420个沟道，能较好地概化流域下垫面特征。（2）模型对年、月、日尺度径流模拟Ens均大于0.51，R2均大于0.55，Re小于10%，模型能够较好地反映罗李村子流域的径流过程，对流域水资源的合理利用具有指导作用。
Abstract:
Distributed hydrological model has become effective approach to simulate hydrologic process and soil erosion. The Luolicun subwatershed was located in the upper reaches of Bahe River in the northwest of China, and was selected as study area. Based on the daily meteorological hydrological data, topography, soil and land use data, the Annualized Agricultural Non-point Source Pollution model (AnnAGNPS) database was built. The best cell was analyzed, and the yearly-monthly-daily runoff of Luolicun subwatershed was simulated. The results showed that:(1) when the critical source area and minimum source channel length were 100 hm2 and 70 m, respectively, the subwatershed was divided into 1030 cells and 420 gullies, and the model can well describe the underlying surface in the watershed; (2) AnnAGNPS model can simulate the runoff process in the study area. The relative error of runoff is less than 10% (Ens=0.51,R2=0.55).
