摘要: In this study, ten best management practices (BMP) were implemented on agricultural areas in the Saginaw River Watershed using Soil and Water Assessment Tool model based four targeting methods (Load per Subbasin Area Index (LPSAI), Load Unit (LPUAI), Concentration Impact (CII), (LII)). The effective BMPs both for non-targeting pollutants contour farming (CF) (except total nitrogen reduction during phosphorus scenario), residue 1000 kg/ha 2000 kg/ha, strip cropping, recharge structures, terracing, native grass (NG). contrast, conservation tillage no did not reduce significant amount of any combination priority areas. regard to spatial correlation between methods, a strong relationship was found LPSAI LPUAI sediment scenarios. addition, similar result CII methods. Regarding spatiotemporal variability BMP implementation plan, distinct change area observed case NG by end second year; however, impact minimal CF due less pollutant efficiency compared NG.
